**** BEGIN LOGGING AT Wed Oct 17 03:00:01 2012 Oct 17 03:02:17 Is there any reason why flash-kernel doesn't allow flashing an older kernel? I.e in the flash-kernel main function, it usees linux-version to obtain the latest kernel version, and will ignore the version given on the command-line if its not the newest... Oct 17 03:03:33 No biggy, I can hack around locally for a quick way to flash an older kernel, but stil... Oct 17 10:47:37 ogra_, did you test the quantal ac100 image recently? I just installed yestsrday's image and have no wifi. Had the same issue previously too Oct 17 10:47:40 so maybe hw issue Oct 17 10:49:18 my install yesterday worked fine Oct 17 11:25:37 ogra_, means my ac100's antenna or something is getting old Oct 17 11:25:53 heh Oct 17 11:30:19 I am trying to compile u-boot with the ubuntu arm toolchain and get the error arm-linux-gnueabi-ld: BFD (GNU Binutils for Ubuntu) 2.22 assertion fail ../../bfd/elf32-arm.c:7498 Oct 17 11:30:24 I guess this is a bug Oct 17 11:36:06 janimo: my wifi and my 3g also died out of the blue Oct 17 11:38:05 marvin24, mine used to have weaker signal than other devices in the same location, but now nothing at all Oct 17 11:38:19 janimo: did you tried the hw mod? Oct 17 11:38:24 no Oct 17 11:38:28 e.g. cutting of some of the alu foil? Oct 17 11:38:30 I don't even know what that is Oct 17 11:38:34 ah Oct 17 11:38:46 no, did not tweak the machine in any way Oct 17 11:39:07 * marvin24 looks for the link Oct 17 11:39:28 janimo: http://www.lins.me/ac100/fixing_wifi.html Oct 17 11:39:35 looks more complicated than it is Oct 17 11:39:49 about feeled 10% of ac100s have this problem Oct 17 11:40:08 problems show up in time? Oct 17 11:40:23 marvin24, thanks for the link Oct 17 11:40:34 don't know, at least you should try it Oct 17 11:40:43 is the wifi device still listed in usb? Oct 17 11:40:49 (or lsusb) Oct 17 11:42:14 * janimo goes to check Oct 17 11:48:58 marvin24, I have a realtek entry there Oct 17 11:49:06 0bda:58f2 Oct 17 11:49:12 janimo: yes, that the camera ;-) Oct 17 11:49:23 wifi is microstar int. Oct 17 11:49:40 (with a realtek chip) Oct 17 11:50:13 mahmoh, then0db0:a871 Oct 17 11:50:21 that's the microstar Oct 17 11:50:49 ok, so forward to hw mod Oct 17 11:50:59 * janimo shudders Oct 17 11:51:06 don't panic Oct 17 11:51:12 the mod itself isnt that hard Oct 17 11:51:20 not today thoug, I needed a tegra quick but if it means so much extra work I'll postpone Oct 17 11:51:21 opening the frame without breaking it is though Oct 17 11:51:29 ogra_, marvin24 ok I may try it Oct 17 11:51:32 sometime Oct 17 11:51:47 I use this device very little though Oct 17 11:51:50 janimo, dont you have a USB wlan NIC ? Oct 17 11:52:02 no Oct 17 11:52:03 might be the quickest way Oct 17 11:52:09 ah, k Oct 17 11:52:17 I used to, bu did not use it in 5 years Oct 17 11:52:20 probably lost already Oct 17 11:52:29 heh Oct 17 13:32:52 XavB: http://live.debian.net/manual/html/live-manual.en.html#440 Oct 17 13:35:56 XavB: or --apt-secure false Oct 17 13:43:24 fabo: thx, I will check that Oct 17 16:23:37 ogra_: hey Oct 17 16:23:59 I have just seen a boot.script file in /boot/ on a pandaboard having ubuntu on it... Oct 17 16:24:09 is that fine? I mean people usually use menu.lst. Oct 17 16:24:21 menu.lst ? Oct 17 16:24:26 just wondering because the kernel dump does not seem to come to the debug poirt... Oct 17 16:24:29 port* Oct 17 16:24:31 yes, definitely. Oct 17 16:24:36 for grub, that. Oct 17 16:24:43 which panda image uses menu-lst ? Oct 17 16:24:49 or which arm image Oct 17 16:24:51 show me one Oct 17 16:25:14 again Oct 17 16:25:27 the kernel dump goes to the debug port on my own pandaboard with stock ubuntu stuff Oct 17 16:25:31 it does not seem to work here. Oct 17 16:25:37 I bet this is due to the boot.script file. Oct 17 16:25:41 otherwise I just cannot imagine. Oct 17 16:25:50 I have just tried terraterm and hyperterminal on my host ... Oct 17 16:25:59 115200 baudrate, proper COM port etc.. Oct 17 16:27:59 ogra_: ^ Oct 17 16:28:37 did you google for "serial port panda ubuntu" yet ? Oct 17 16:28:56 djszapi: Not sure what you are trying to do, but first off, no arm images that I am aware of have ever used grub or menu.lst. Oct 17 16:29:16 GrueMaster: that is pointless. Oct 17 16:29:22 I told what I am trying to do. Oct 17 16:29:31 They mostly use uboot, an it uses boot.scr which is a crc signed boot script. Oct 17 16:29:36 17:25 < djszapi> the kernel dump goes to the debug port on my own pandaboard with stock ubuntu stuff Oct 17 16:29:40 17:25 < djszapi> it does not seem to work here. Oct 17 16:30:09 djszapi, seriously, thats a beginner task you are trying to do, that has been documented 100 times out there Oct 17 16:30:12 just goodle it Oct 17 16:30:15 *google Oct 17 16:30:26 and I have used thousand times... Oct 17 16:30:30 and the same stuff does not work... Oct 17 16:30:36 not sure what to google about that one. Oct 17 16:30:41 where I can find any result. Oct 17 16:30:53 17:25 < djszapi> I have just tried terraterm and hyperterminal on my host ... Oct 17 16:30:59 17:25 < djszapi> 115200 baudrate, proper COM port etc.. Oct 17 16:31:09 should be the matter of baud rate speed and COM port nothing else... Oct 17 16:31:38 if it is a beginner task, why does nobody know here? Oct 17 16:32:14 djszapi: You need to enable the serial console in the boot.scr. Try ggogling for that. Oct 17 16:33:12 GrueMaster: that should be enabled by default. Oct 17 16:33:16 after flashing. Oct 17 16:33:16 no Oct 17 16:33:27 it is enabled by default in the server images only Oct 17 16:33:27 yes, it worked previously by default after flashing. Oct 17 16:33:31 as documented Oct 17 16:33:38 never in ubuntu Oct 17 16:33:38 No, it shouldn't. Not for desktop. Oct 17 16:33:54 except that is it not desktop. Oct 17 16:33:57 it * Oct 17 16:34:34 well, did you edit boot.script ? Oct 17 16:34:37 no Oct 17 16:34:49 and does it have a console= entry Oct 17 16:35:30 in any case all server images up to 12.04 default to console Oct 17 16:35:47 and desktop images never has serial Oct 17 16:35:54 *had Oct 17 16:45:39 ogra_: yes, I have. Oct 17 16:45:56 console=tty02,115200n8 Oct 17 16:46:21 so that should put out kernel images to serial Oct 17 16:46:28 I tried to modify that a bit Oct 17 16:46:36 but the kernel does not seem to boot anymore... Oct 17 16:46:51 it is stuck at the ubuntu and progress stuff screen... Oct 17 16:46:58 any ways I can get it back to life? Oct 17 16:47:13 how did you modify ? Oct 17 16:47:13 without reflashing? Oct 17 16:47:30 console had a different value there. Oct 17 16:47:36 and I modified to that value above. Oct 17 16:47:37 as that was on the wikipage. Oct 17 16:47:43 the proper wy is edit /boot/boot.script and run sudo flash-kernel Oct 17 16:47:55 on the running installation Oct 17 16:47:58 I just edited, and then sudo reboot. Oct 17 16:48:10 that wouldnt have changed anything Oct 17 16:48:16 which makes it nonbootable, frank... Oct 17 16:48:26 flash-kernel (like update-grub) is the thing that applies the changes to the bootloader Oct 17 16:48:49 so if you only edited /boot/boot.script you didnt make any changes at all to the bootloader Oct 17 16:49:24 ergo, your breakage is cause ny something else Oct 17 16:49:46 maybe. Oct 17 16:52:58 ogra_: does not still work after flash-kernel Oct 17 16:53:03 still nothing on the debug port. Oct 17 16:53:36 setenv bootargs rw vram=32M fixrtc mem=1G@0x80000000 root=/dev/mmcblk0p2 console=ttyO2,115200n8 rootwait Oct 17 16:53:46 the file is using uuid here, and most likely mmcblk0p1 Oct 17 16:53:56 should the console then be tty01? Oct 17 16:54:09 is it an 'O' character or '0' number as zero? Oct 17 16:54:23 I guessed the digit stuff. Oct 17 16:54:25 OHH, not ZERO. Oct 17 16:55:23 You can also add "ealryprintk=ttyO2,115200n8" for kernel boot messages prior to initrd. Oct 17 16:55:55 Are you able to log into the booted system? Oct 17 16:56:10 I do not need kernel stuff printed. Oct 17 16:56:16 also, the wiki seems to need some improvement... Oct 17 16:56:28 Which wiki? Oct 17 16:56:30 to mention it is actually not a digit in there, but the character... Oct 17 16:56:36 http://www.omappedia.com/wiki/OMAP_Ubuntu_Core Oct 17 16:57:04 Ubuntu does not control that wiki. Oct 17 16:57:12 not that ttyO2 would work though Oct 17 16:57:19 like I asked, should it be ttyO1? Oct 17 16:57:36 since the mmcblk0p2 stuff is also mmcblk0p1 in the reality. Oct 17 16:57:53 it does not matter who controls that Oct 17 16:58:00 the wiki has to be improved to avoid frustrations like this. Oct 17 16:58:07 No. Two entirely different things. Oct 17 16:58:28 mmcblk0p1 cant be used for a rootfs Oct 17 16:58:36 it holds the bootloader data Oct 17 16:58:38 And I had proper instructions on the ubuntu wiki. That is supported by the ubuntu arm team. Oct 17 16:59:01 which page? Oct 17 16:59:05 it does not work anyways Oct 17 16:59:08 even with ttyO2 Oct 17 16:59:11 further ideas? Oct 17 16:59:24 can confirm it with hyperterminal and terraterm as well Oct 17 16:59:41 is it really this hard to get a darn debug port up on a desktop image ?:O Oct 17 16:59:51 shouldn't there be a ui action for this all Oct 17 17:00:14 it should not be this painy. Oct 17 17:00:45 well, it isnt ... Oct 17 17:00:48 use a server image Oct 17 17:01:00 it is out of my authority to reinstall anything Oct 17 17:01:05 and to be honest, I would not do that for fun... Oct 17 17:01:23 well, then stop complaining Oct 17 17:01:26 why is this hard to enable the damn kernel dump? Oct 17 17:01:37 should be a checkbox in the settings, and everything done magically. Oct 17 17:01:41 it is enabled by default if you use the right image Oct 17 17:02:35 Wait, are you trying to enable a serial console port for post-boot debugging? Oct 17 17:02:46 no Oct 17 17:02:57 I am trying to enable the damn prompt and so forth Oct 17 17:03:11 to get a reasonable development environment where I do not have to switch the damn keyboard and mouse forth and back. Oct 17 17:03:21 between the board and my computer since that is just stupid. Oct 17 17:03:59 aka. to actually develop on the board. Oct 17 17:04:06 Do you need the desktop environment on the panda? If not, then use the server image. If so, hook up a keyboard and mouse and develop on it like a normal desktop. Oct 17 17:04:08 looks super painy so far... Oct 17 17:04:23 like I said several times, it is not my scope to change anything in the system. Oct 17 17:04:29 This is not an embeded environment. Oct 17 17:04:41 and surely, we would not like to get such a risk in a commercial project by any mean before the deadline. Oct 17 17:05:17 I do not know what you are talking about :D Oct 17 17:05:22 the world is not black and white. Oct 17 17:05:32 yes, there are embedded environment with UI without being desktop or server... Oct 17 17:05:46 Not in Ubuntu. Oct 17 17:05:49 environments* Oct 17 17:05:56 THis is not an embedded distro. Oct 17 17:06:00 it is not Ubuntu specific Oct 17 17:06:06 it is a generic requirement. Oct 17 17:06:16 and no, server install will have other pains with ui... Oct 17 17:06:24 so it is a quite unreasonable choice it would be. Oct 17 17:06:46 so ubuntu arm is not recommended for embedded? Oct 17 17:06:49 shall I take it so? Oct 17 17:07:02 how so? use server image, install ubuntu-desktop, done. Oct 17 17:07:09 HAHAHA Oct 17 17:07:14 server and install desktop :D Oct 17 17:07:15 hard to consider pandaboard as embedded Oct 17 17:07:21 reasonable thingie instead of desktop install directly :D Oct 17 17:07:22 And no, ubuntu-arm was not designed for the embedded environment. Oct 17 17:07:53 hrw: then your imagination is weak :D Oct 17 17:08:01 djszapi: grab debootstrap, create minimal rootfs. add kernel to it, boot pandaboard Oct 17 17:08:05 just look around, android, touch screen devices, etc Oct 17 17:08:05 Not entirely unreasonable. When I did QA on ubuntu, I would test this all the time. Oct 17 17:08:08 full of embedded stuff Oct 17 17:08:20 djszapi: for me arm926 is embedded Oct 17 17:08:37 to be honest, I do not care about any flamewar what is embedded or not. Oct 17 17:08:42 djszapi: I started using linux on ARM in 2004 on strongarm Oct 17 17:08:49 and like I said several times by now, why on earth arguing about something I cannot do? Oct 17 17:08:55 why not just get the damn serial port work? Oct 17 17:09:04 everything else is hijack and unproductive. Oct 17 17:09:30 hrw: I started around 2000 Oct 17 17:09:56 anyway, this does not still work and I ran out of the ideas... Oct 17 17:10:07 djszapi: edit /boot/boot.* to set console=ttyO2, edit /etc/inittab to enable getty - or rather go to /etc/init/ and make copy of tty1.conf as ttyO2.conf and adapt it Oct 17 17:10:13 If you want boot logging for the serial port, you have the boot.script modifications. If you want a serial log in, you need to create an /etc/init/ttyO2.conf with the proper settings. Simple. Oct 17 17:10:39 GrueMaster: where is that even documented? Oct 17 17:10:43 djszapi: so 12 years in embedded linux and you have such silly problems? Oct 17 17:11:06 djszapi: aren't you from management not development teams? Oct 17 17:11:22 hrw: please stay civil. Oct 17 17:13:26 djszapi: Please understand, it is very difficult to help when you really haven't stated what you are trying to do. If you are trying to do remote gdb with the serial port, google it (using ttyO2 instead of ttyS0 in the instructions). It isn't rocket science. Oct 17 17:14:09 I honestly do not know how I can say more clearly I wanna have a development environment instead of switching my keyboard and mouse just like I said above. Oct 17 17:14:14 what is unclear about this? Oct 17 17:14:24 Panda uses ttyO2 for the 9 pin serial port. YOu don't need a null modem cable, just a 9 pin serial cable from your desktop system. A usb to 9 pin will just plug in and work. Oct 17 17:14:27 Everybody knows doing that, and editing files directly on a board, is just super painy. Oct 17 17:14:59 Why not use vnc or ssh? Faster than serial port anyways? Oct 17 17:15:27 yeah and a publicly usable network will be born here off-hand... Oct 17 17:15:31 out of the thin air... Oct 17 17:16:04 Take a network cable, plug one end into your panda, the other into your desktop/laptop. Simple. Oct 17 17:16:15 Basic network 101. Oct 17 17:16:36 yeah, how glorius to lose the network on my host PC in the meantime... Oct 17 17:16:44 genius "Basic network 101" idea... Oct 17 17:17:13 So, plug in a network switch. Duh. Oct 17 17:17:38 ah yes, getting simpler! Oct 17 17:17:42 more and more factors, please! Oct 17 17:17:48 instead of a simple usb-serial dongle... Oct 17 17:18:02 The Ubuntu Desktop image for arm is exactly that, a desktop image. If you want to develop on it, you do it the same as you would an x86 desktop. Oct 17 17:18:30 And I already told you how to use the serial console. Oct 17 17:20:06 djszapi: please. explain 'a development environment' Oct 17 17:20:22 djszapi: you got info how to connect and use serial console Oct 17 17:20:34 djszapi: how to connect ethernet network Oct 17 17:21:03 djszapi: you can even boot panda over nfs, nbd, aoe, iscsi Oct 17 17:21:05 no, I did not get unvague information so far. Oct 17 17:21:18 djszapi: please. explain 'a development environment' then. in simple 20 words Oct 17 17:21:19 none that would make sense to me so far. Oct 17 17:21:31 actually I asked for documentation where it is described and I got ignored for that question. Oct 17 17:21:33 and then we can continue discussion. Oct 17 17:21:46 and no, there is no /etc/init/ttyO1.conf so nothing to adapt... Oct 17 17:21:51 djszapi: consider most people here as desktop users ok? Oct 17 17:21:54 so that suggestions was actually incorrect... Oct 17 17:22:28 suggestion* Oct 17 17:22:29 djszapi: mv /etc/init/tty1.conf /etc/init/ttyO2.conf and edit? Oct 17 17:22:35 eeek Oct 17 17:22:40 dont mv :) Oct 17 17:22:45 ops, cp ;D Oct 17 17:22:48 cp please :) Oct 17 17:23:05 ogra_: for headless it does not matter anyway Oct 17 17:23:17 djszapi: please. explain 'a development environment' then. in simple 20 words. Oct 17 17:23:27 hrw: read above. Oct 17 17:23:51 thats like ten pages :P Oct 17 17:23:55 he said 20 words Oct 17 17:23:55 djszapi: your discussion is over 10 pages Oct 17 17:24:11 djszapi: if you are unable to tell what you need in 20 words then it is useless discussion Oct 17 17:24:57 "I want to boot Ubuntu on pandaboard, have serial connection and a way to alter rootfs while it is running" - 20 words for one usecase Oct 17 17:25:13 honestly, I do not know what makes you doubt. Oct 17 17:25:36 djszapi: I would like to help but reading 10 pages of discussion is waste of time Oct 17 17:25:38 I would like to develop a software on my host machine while being on the board. Oct 17 17:25:42 what is so hard to imagine about it? Oct 17 17:25:58 like I said, switching keyboard and mouse is not fun. Oct 17 17:25:58 nwhy would that need serial ? Oct 17 17:26:07 because I can have a prompt? Oct 17 17:26:15 so install ubuntu on board, use cross compiler on desktop and scp/ftp/nfs/whatever files between them? Oct 17 17:26:26 *sigh* Oct 17 17:26:26 So, buy another mouse/keyboard. THey're cheap. Oct 17 17:26:32 djszapi: and 'ssh pandaboard.local' is so hard? Oct 17 17:26:39 I wonder if people kid with me here. Oct 17 17:26:45 like "So, buy another mouse/keyboard. THey're cheap. Oct 17 17:26:46 " Oct 17 17:27:03 No. No one is kidding. We're just getting frustrated. Oct 17 17:27:06 and one would still need to switch the hmi and monitor anyways. Oct 17 17:27:13 so that is just a big no go by its nature. Oct 17 17:27:20 We have given you all the solutions. Oct 17 17:27:27 hrw: ssh with thin air? Oct 17 17:27:29 it can go through? Oct 17 17:27:34 sudo apt-get install openssh-server Oct 17 17:27:39 GrueMaster: no, there was none given Oct 17 17:27:41 djszapi: ethernet is too expensive? Oct 17 17:27:43 ssh into your board and be happy Oct 17 17:27:45 Why can't you put it on your network? Oct 17 17:27:46 I asked for a documentation twice and both were ignored. Oct 17 17:27:53 hrw: ethernet without a networjk? Oct 17 17:27:55 network* Oct 17 17:28:12 djszapi: sorry, I did not know that your development costs have to be under 1€ Oct 17 17:28:15 Panda has both wifi and ethernet. Oct 17 17:28:26 hrw: huh? Oct 17 17:28:32 * djszapi thinks people got into kidding Oct 17 17:28:44 djszapi: ever heard of usbnet? just microusb cable needed and a bit of configuration Oct 17 17:28:57 or miniusb - I do not remember panda connector for otg Oct 17 17:29:06 hrw: how on earth is that simpler than a proven serial port connection with usb-serial dongle? Oct 17 17:29:09 especially if that is at hand... Oct 17 17:29:24 it does not use microusb Oct 17 17:29:28 well, or just enable serial Oct 17 17:29:30 djszapi: so connect that FUCKING adapter, edit one FUCKING file and live with it! Oct 17 17:29:32 and no, the phone cables are not good for this, like N9 Oct 17 17:29:38 hrw, ! Oct 17 17:29:43 jesus. Oct 17 17:29:44 so no, i tis a big no go without a cable right now, especially when I have serial-usb dongle. Oct 17 17:30:01 djszapi: YOu will need to create an /etc/init/ttyO2.conf file then. Sorry for the inconveinience, but this is easily done with a keyboard/mouse/monitor. Oct 17 17:30:03 fourth time: documentation? Oct 17 17:30:09 my 4.5y daughter would understand how to develop linux kernel drivers in shorter time Oct 17 17:30:11 * djszapi will get ignored again most likely Oct 17 17:30:18 yes Oct 17 17:30:23 Fifth time. GOOGLE. Oct 17 17:30:25 the way you behave isnt pleasant Oct 17 17:30:35 so people arent likely to help you Oct 17 17:30:51 * hrw -> moleman 2 movie. demoscene is more interesting Oct 17 17:30:54 isn't pleasant to reject ethernet when it is impossible to use? Oct 17 17:31:00 is pleasant* Oct 17 17:31:05 yes, that is very unpleasant. Oct 17 17:31:12 sorry, cannot do anything about it, I am afraid. Oct 17 17:31:50 djszapi: How do you normally do desktop development on a remote system? Apply the same principles here. Oct 17 17:32:30 djszapi: pandaboard has: serial (very easy to get login on it and we told that atleast 3 times), otg usb port (easy to get usb networking over it with simple mini/microusb cable), ethernet (with second network card in pc or switch it works), wifi (with accesspoint or hostap on laptop/desktop it works) - each of them can get running in <10 minutes Oct 17 17:32:54 most of them with information which was on this channel during last hour Oct 17 17:32:57 to be fair, even this documentation I linked previously had no information: http://www.omappedia.com/wiki/OMAP_Ubuntu_Core Oct 17 17:33:01 that is about google .... Oct 17 17:33:36 1) I did not get documentation, no. Oct 17 17:33:38 On your panda, to enable a serial login prompt, you need to create a /etc/init/ttyO2.conf (easiest is to copy an existing one) and have "exec /sbin/getty -8 115200 ttyO2" in it. Then reboot. Oct 17 17:33:45 2) I do not have miniusb cable here now, but I have serial-usb dongle Oct 17 17:33:53 3) I do not have hostap at all on the host. Oct 17 17:34:26 See my above instructions. If you don't care to follow them, I CAN"T HELP YOU. Oct 17 17:34:27 I provided the google result, so then again: what documentation if even the OMAP Ubuntu ARM documentation is untrustworthy regard to this? Oct 17 17:34:41 Shall I say again, it could have a room for improvement? Oct 17 17:34:44 even http://www.omappedia.com/wiki/OMAP_Ubuntu_Core describes how to get panda running with ubuntu. a bit overworked way but easy one Oct 17 17:35:06 the task is NOT to get panda running with ubuntu Oct 17 17:35:07 just follow steps. do not think, follow Oct 17 17:35:13 the task is to get a login prompt over the serial port. Oct 17 17:35:21 djszapi: this page describes that as well Oct 17 17:35:25 and no, that is not documented there as "suggested" above. Oct 17 17:35:30 http://www.omappedia.com/wiki/OMAP_Ubuntu_Core#Getting_a_Terminal_on_the_same_serial_port_as_for_the_console Oct 17 17:35:47 18:35 < djszapi> and no, that is not documented there as "suggested" above. Oct 17 17:35:56 that writes an entirely different thing Oct 17 17:36:04 no /etc/init/tty02.conf mentioned there. Oct 17 17:36:09 but perhaps my ctrl-f lies. Oct 17 17:36:20 djszapi: it uses other way for it ok? more complicated one Oct 17 17:36:36 that is what I was saying... Oct 17 17:36:36 from the beginning... Oct 17 17:36:44 * hrw -> movie Oct 17 17:36:48 and that is why I asked the damn documentation about the "not so complicated one"... Oct 17 17:36:49 have a nice weekend djszapi Oct 17 17:37:00 it is not any close to weekend yet :D Oct 17 17:37:35 * GrueMaster goes back to day job. Oct 17 17:38:28 http://omappedia.org/wiki/PandaBoard_Ubuntu_How-tos#How_to:_set_up_a_console -> this should have linked an hour ago Oct 17 17:38:43 and not still convincing do the "more complicated one". Oct 17 17:39:10 this is not really helpful for novices. Oct 17 17:39:51 What is wrong with the instructions I just gave you? If you are a developer, surely you know how to edit a text file. Oct 17 17:41:45 edit to what? Oct 17 17:41:53 I am a mind reader how it works on ubuntu arm for pandaboard? Oct 17 17:42:17 am I a wrong person if I would like to ask for a documentation that novices have to go through? Oct 17 17:42:38 perhaps in this channel, yes. Oct 17 17:42:43 [10:33:35] On your panda, to enable a serial login prompt, you need to create a /etc/init/ttyO2.conf (easiest is to copy an existing one) and have "exec /sbin/getty -8 115200 ttyO2" in it. Then reboot. Oct 17 17:43:12 Do I need to do a presentation with slides? Oct 17 17:44:50 is this the ubuntu arm way for user feedback? Oct 17 17:45:01 if something is unclear I should not tell that? Oct 17 17:45:14 and then you have to ask questions like "huh, n00b, do I have to make a presentation with slides"? Oct 17 17:45:19 what is unclear from my instructions? Oct 17 17:45:27 the whole Oct 17 17:45:45 I would like to see a documentation what a person can check about the /full content/ of the file without coming to IRC. Oct 17 17:45:50 but I posted that anyway Oct 17 17:45:59 it may just have been more time for me than an experienced person here. Oct 17 17:46:07 feel free to write documentation if you are missing any Oct 17 17:46:54 not to mention, it does not still work anyways. Oct 17 17:47:02 empty hyperterminal and terraterm in the end Oct 17 17:47:09 works fine here Oct 17 17:47:40 using a server image Oct 17 17:47:41 so I would still need help as I have no more clue... Oct 17 17:47:54 And on my 5 pandas I have running at home. I can remotely log into my home network, and see every single one one from my serial console server. Oct 17 17:47:55 and guess what, it also works on the desktop image where i enabled it manually Oct 17 17:48:31 I think the problem you are having is that you don't have your Windows system setup correctly. Oct 17 17:48:43 means? Oct 17 17:48:47 (since you are using hypertermial). Oct 17 17:49:01 do nto know what you mean. Oct 17 17:49:14 Try installing putty for Windows. It has better serial console support. Oct 17 17:49:26 GrueMaster, well, i guess his problem is that he doesnt use a proper ubuntu image Oct 17 17:49:43 What are you running on your desktop image? Oct 17 17:49:57 better: how did that get installed ? Oct 17 17:50:18 GrueMaster: UI applications, but that is pointless now. Oct 17 17:50:24 I mean I have to get it work Oct 17 17:50:29 so far it is more than an hour to get it work with help. Oct 17 17:50:30 Or what OS is on your desktop (better question). Oct 17 17:50:36 any other ideas why it does not work _now_? Oct 17 17:50:55 Windows XP Professional 2002. Oct 17 17:51:02 if we knew how exactly you did set that system up probably Oct 17 17:51:11 (the panda not the win) Oct 17 17:51:12 AHA! Finally progress. Oct 17 17:51:23 Now, Download putty and install it on your XP system. Oct 17 17:51:27 why? Oct 17 17:51:38 ogra_: Problem is on Windows. Oct 17 17:51:39 I would like to use hyperterminal or terraterm. Oct 17 17:51:48 GrueMaster, ah, k Oct 17 17:51:54 Ok, fine. Oct 17 17:52:15 GrueMaster, but he doesnt want to get help Oct 17 17:52:22 Make sure you have hyperterminal configured for the usb serial port then. Oct 17 17:52:30 * ogra_ guesses djszapi just wants to troll and goes back to do actual work Oct 17 17:52:34 * GrueMaster ignores ogra for the moment. Oct 17 17:52:36 GrueMaster: heh, do you seriously think I did not? :D Oct 17 17:52:43 I have even checked in the device manager in the very beginning. Oct 17 17:52:59 ogra_: yeah, sure I would not like to solve it ... Oct 17 17:53:02 friendly guess... Oct 17 17:53:02 GrueMaster, liek djszapi is ignoring my questions you mean ? :P Oct 17 17:53:10 djszapi: Do you see anything in hyperterminal when you boot your panda? Oct 17 17:53:13 anyway, back to work Oct 17 17:53:18 GrueMaster: nope Oct 17 17:53:34 THen you don't have it configured properly. Oct 17 17:53:39 PLain and simple. Oct 17 17:53:55 how do you *really* know it is not a panda issue? Oct 17 17:53:57 YOu should at least see uboot messages when you power on the panda. Oct 17 17:54:20 I can verify this at least with two different terminal programs: hyperterminal and terraterm. Oct 17 17:54:36 so I think it is rather a panda issue than windows terminals. Oct 17 17:54:42 because it happens in both applications. Oct 17 17:54:47 Because I used to do the QA for Ubuntu since '09 on arm systems. I also have 5 panda platforms, 2 Beagles, and a box of other systems. Oct 17 17:54:53 which kinda makes me think, it is not the fault of one or the other. Oct 17 17:55:25 And I now work at Intel and have setup multiple serial consoles to Intel server platforms. Oct 17 17:55:39 So, I have plenty of experience in this. Oct 17 17:55:44 so...? Oct 17 17:55:47 you know everything? Oct 17 17:55:51 every esoteric use cases? Oct 17 17:55:57 either way, usb-serial port is COM3 Oct 17 17:56:06 adn that is what I have setup up in the beginning as well anyways Oct 17 17:56:07 No, only the realistic ones. Oct 17 17:56:12 along with baud 115200 Oct 17 17:56:22 I do nto think I should set up more than that. Oct 17 17:56:30 I do not even know what can go wrong with those two setups. Oct 17 17:56:37 I mean I set those, and done. Oct 17 17:56:42 Do you have anything plugged in between the usb serial cable and the panda? Oct 17 17:56:42 that should be done on the Windows side. Oct 17 17:56:55 nope Oct 17 17:57:19 Do you have anything else you can plug into the serial port to verify it works? Oct 17 17:57:30 nope Oct 17 17:57:53 but presumably I can make a short circuit for the TX/RX on the panda side.. Oct 17 17:57:57 Note that I have seen a few bad serial cables in my time. Oct 17 17:58:12 Why? THat won't solve anything. Oct 17 17:58:54 it will Oct 17 17:59:00 I will see if the cable works in the terminal Oct 17 17:59:21 so IMHO it is a good verification for the cable. Oct 17 17:59:47 2-3 pins. Oct 17 17:59:53 With the possibility of blowing out the serial controller on the panda. Oct 17 18:00:08 huh? Oct 17 18:00:19 it would not be connected to the panda that is the whole point... Oct 17 18:00:20 Which Ubuntu image are you using on the panda? Oct 17 18:00:23 to just test the cable... Oct 17 18:00:38 Oh, then that may work. Oct 17 18:02:30 weird nothing. Oct 17 18:02:36 I should see what I type. Oct 17 18:02:47 So...maybe bad cable? Oct 17 18:02:58 it is a usb-serial dongle, but with two serials on that end. Oct 17 18:03:08 and then there is a Reset A and Reset B button. Oct 17 18:03:20 have not used such a cable so far. Oct 17 18:03:26 What is the make/model of that cable? Oct 17 18:03:29 but presumably it should just work if one serial is plugged. Oct 17 18:03:31 no clue Oct 17 18:03:50 according to the device manager it uses FTDI at least. Oct 17 18:04:23 2 9-pin connectors on one end? THen it should show up as two serial ports in device manager. Oct 17 18:04:31 usb to dual serial converter Oct 17 18:04:37 that is what is on the box. Oct 17 18:04:53 right. I have a 4-port usb-serial cable at home. Oct 17 18:05:20 Multi-Serial Station. Oct 17 18:05:51 So try the other port, or change the port in hyperterminal. Oct 17 18:06:31 I will take a screenshot :D Oct 17 18:06:36 sorry, picture with my phone. Oct 17 18:08:26 http://imagebin.org/232295 Oct 17 18:08:41 http://imagebin.org/232296 Oct 17 18:11:03 Like I said, it should show up as two ports in Windows (com3 & com4 likely). Oct 17 18:11:16 that is not the problem Oct 17 18:11:20 the problem is that it does not seem to work. Oct 17 18:11:23 So if one doesn't work, try the other. Oct 17 18:11:26 even for short circuit with my house key. Oct 17 18:11:28 Are you sure? Oct 17 18:11:41 yes Oct 17 18:11:42 Can't help with that. Oct 17 18:11:59 I should see what I type, but I do not. Oct 17 18:12:15 ok now it works. Oct 17 18:12:53 Good, now plug it into the panda and reboot the panda. Oct 17 18:13:13 one of the ports seems to be broken... Oct 17 18:13:18 If you don't see uboot messages, then something else is wrong. Oct 17 18:14:11 I do not understand. Oct 17 18:14:13 it works randomly :D Oct 17 18:14:45 I would suggest getting a different serial-usb cable. Oct 17 18:15:15 everybody knows that is the last thing one does in a company. Oct 17 18:16:05 Not everyone. I always check everything before blindly blaming (and flaming) one group. Oct 17 18:16:35 Eliminate all variables. Basic developer skill. Oct 17 18:16:57 cable is the last thing to blame... Oct 17 18:17:02 (and not just software/hardware development). Oct 17 18:17:13 especially when it is a hassle to get a new one like here and at other many places... Oct 17 18:17:58 Well, I don't know where "here" is for you, but amazon has good cables and fast delivery. Oct 17 18:18:08 yeah, the panda is still broken Oct 17 18:18:13 short circuit works just fine. Oct 17 18:18:27 we do not have time for delivery. Oct 17 18:18:29 that is the point. Oct 17 18:19:04 not that poor devs would manage the ordering at a big company anyways Oct 17 18:19:10 it has a bunch of communication chain anyways Oct 17 18:19:17 which you really wanna avoid in a big company Oct 17 18:19:19 lot of communication Oct 17 18:19:31 either way: short circuit works, panda does not. Oct 17 18:19:40 I work at Intel. It doesn't get much bigger. Oct 17 18:20:10 it does, a supervisor has to escalate. Oct 17 18:20:14 and someone has to approve that Oct 17 18:20:16 And unless you can hook that serial cable up to another device and get it working, I am not rulling out the panda. Oct 17 18:20:20 so it is at least a communication between three. Oct 17 18:20:27 For a $10 cable? Oct 17 18:20:36 anyways, the cable is not the artefact just like I thought. Oct 17 18:20:50 for any cost, yes. Oct 17 18:20:54 it is not the kindergarden :D Oct 17 18:20:59 people do random stuff around as they wish. Oct 17 18:21:08 You can rule it out because it works with your house key? Oct 17 18:21:12 it has proper organization and unified processes to follow. Oct 17 18:21:27 yes, I can rule out of course because it works fine for short circuit. Oct 17 18:21:36 I can very confidentally rule that out. Oct 17 18:22:08 I can very confidently not rule it out. Oct 17 18:22:15 blaming a cable is easy even it poor cable has nothing to do with buggy software, os, etc. Oct 17 18:23:09 You know what, I have tried to be more than patient here. I can't help you any more. Oct 17 18:26:58 I think I got work finally. Oct 17 18:27:08 it* Oct 17 18:27:44 thank you for the help Oct 17 18:29:15 djszapi: but you have sd card with MLO and u-boot.bin on it in pandaboard's slot? Oct 17 18:30:14 cause pandaboard lacks any flash on board so without SD it is just dead on serial Oct 17 18:32:36 I have sd card, yes. **** ENDING LOGGING AT Thu Oct 18 03:00:01 2012
