**** BEGIN LOGGING AT Mon Apr 03 03:00:02 2017 Apr 03 04:14:55 Hi Apr 03 04:16:01 I get a problem with my beaglebone black which my LED 2 will solid on after connect to the computer. also, the usb drive does not show up. Apr 03 04:17:46 I got a problem with my beaglebone black which my LED 2 will solid on after connecting to the computer and also the usb drive does not show up in my computer.. Apr 03 04:22:01 Guest94742: sounds like it stalls in the bootloader Apr 03 04:22:24 Guest94742: do you have the debug UART wired up? Apr 03 04:23:12 I am so sorry since I am new to BeagleBone Black, I have no idea what is UART Apr 03 04:24:13 Basically I was trying to flash my beaglebone black and I didn't manage to do it and I did pressed the power button. Does it matter Apr 03 04:28:34 sounds like somethin went wrong in that context Apr 03 04:28:57 try removing the card and not pressing the button and see if it boots Apr 03 04:30:22 so right now when connecting to the power, after the default blinking, only the user LED2 solid on.( without SD card) Apr 03 04:30:59 ok, then you need to reflash Apr 03 04:31:34 With the SD card, after i plug in, only the LED 0 keep blinking like heart beat Apr 03 04:32:09 and nothing else, I thought it supposed to blink in sequence like 012321012321....... Apr 03 05:01:45 then the sd card has simply booted. you'll have to refer to the documentation on how to make it go into flashing mode Apr 03 05:15:08 best to download a flasher image .. if you still can .. Apr 03 05:15:28 I think they exist .. but not so widely published. Check the page on elinux/Debian .. Apr 03 05:16:01 then power-up the board, with uSD card in, whilst holding the BOOT button next to the uSD card slot .. until you see LEDs blinking Apr 03 05:16:09 iirc ^_^ Apr 03 05:16:45 i did download it and write the image into the sd card Apr 03 05:17:43 but after all the LEDs blinking, only the LED 0 keep bliking like heartbeat eventually Apr 03 05:19:01 I have no idea whether it is in progress since I had been told that all the LEDs supposed to blink in sequence when it is flashing Apr 03 05:22:08 you didn't download a flasher Apr 03 05:22:15 it's now simply running from SD card Apr 03 05:22:17 not flashing Apr 03 05:23:30 Thanks for the reply, i downloaded "bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img" and did write it on my SD card Apr 03 05:23:46 which is not a flasher Apr 03 05:24:21 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian see table of contents there Apr 03 05:24:34 you find "Flasher: (lxqt-4gb) (All BeagleBone Variants with a 4GB eMMC)" if you want a GUI Apr 03 05:24:55 "Flasher: (iot) (All BeagleBone Variants)" if you don't need/want a GUI Apr 03 05:26:00 I did edit /boot/uEnv.txt, and remove the "#" Apr 03 05:26:14 is this the crucial step? Apr 03 05:26:17 well it doesn't sound like it worked Apr 03 05:26:22 since it's not flashing Apr 03 05:28:11 other than this problem, when I plug my Beaglebone black in without the SD card, after the default blinking for a while, only the LED 2 solid on. Apr 03 05:28:51 difficult to diagnose, but sounds like it might be a kernel panic Apr 03 05:28:58 My computer is unable to detect the usb drive right now, does it matter and related? Apr 03 05:29:35 your computer can only detect it as a usb device if it's started up properly and still running Apr 03 05:30:10 I am so sorry since I am really new to this. I need help bacause everything went wrong. Can I get some idea of what should i do now? Apr 03 05:30:18 reflash it Apr 03 05:30:33 I just told you where you can find flasher images Apr 03 05:34:10 so meaning it supposed to be "BBB-blank-debian-8.7-lxqt-4gb-armhf-2017-03-26-4gb.img.xz" instead of "bone-debian-8.7-lxqt-4gb-armhf-2017-03-26-4gb.img.xz" Apr 03 05:34:13 ? Apr 03 05:38:09 yes Apr 03 05:39:11 zmatt: I thought they were named 'flasher' too .. Apr 03 05:39:28 or has rcn changed the builds again lol Apr 03 05:40:12 they're listed as "flasher" on the wiki page, but this is what the image name has looked like for at least quite a while Apr 03 05:40:15 for some reason Apr 03 05:40:22 okies Apr 03 05:44:49 so i should do the same thing which is writing the image into the SD card and press the S2 button of beaglebone before power on, am i right? Apr 03 05:51:04 the S2 button is usually not even necessary Apr 03 06:17:09 I am new to beaglebone black. The problem that i am facing: my computer doesn't show up the usb drive even if i plug my BBB, Apr 03 06:18:57 2. I tried to flash my beaglebone (insert the SD card with the image written), and LED 0 and 1 blinking at first, after that only LED 0 keep blinking and nothing happen Apr 03 06:22:28 I managed to flash "BBB-blank-debian-8.7-lxqt-4gb-armhf-2017-03-26-4gb.img.xz" but now when I use putty to connect root@192.168.7.2, it required a password, can anyone helps? Thanks in advance Apr 03 06:48:39 Guest44081: try username debian and password temppwd Apr 03 06:50:45 it works, but i supposed to log in by using root as last time when i used Apr 03 06:51:04 but it requires password Apr 03 07:11:26 try 'root' Apr 03 07:11:36 Guest44081: log in as user debian and use sudo Apr 03 07:11:51 ver|laptop: he's trying ssh, probably root login is disabled there Apr 03 07:14:50 oh shoot yeah it would. Apr 03 07:14:54 default openssh opts Apr 03 07:16:39 ?? Apr 03 07:16:49 sorry that I am new to beagle bone Apr 03 07:16:58 and new to linux?! Apr 03 07:17:12 not really Apr 03 07:17:22 but I was trying to flash my beaglebone Apr 03 07:17:53 and still i am not able to do it after so long Apr 03 07:18:43 can anyone helps? will be really appreciate. Apr 03 08:26:17 Hi, after flashing the Beaglebone black, it requires password for root. how can i solve it? Apr 03 08:30:00 after flashing beaglebone black, it requires a password when login as root. neither blank nor root is the password Apr 03 08:30:06 can anyone help? Apr 03 08:51:12 zene: try logging in as the default user and then use sudo Apr 03 08:52:20 you can set the password with 'sudo passwd root' Apr 03 08:58:54 tbr: I guess he's trying to log in via ssh Apr 03 08:59:02 tbr: and there, root login is likely disabled Apr 03 08:59:51 thinkfat: yes, hence my recommendation to log on as default user (debian?) and then use sudo Apr 03 09:00:11 I think we might be talking to a bot .. LOL Apr 03 09:00:34 Default user: debian pass: temppwd Apr 03 09:00:55 likely closed the page long ago Apr 03 09:17:05 sorry Apr 03 09:17:28 i am wondering why do i have to login as debian Apr 03 09:17:48 is it the same with root? since i used to login as root without password Apr 03 09:37:15 sounds like you were running some really really old image or some third party image Apr 03 09:38:11 you can probably achieve that too, but need to go through deliberate steps. (Which was probably the intention, given how horribly insecure it becomes) Apr 03 09:38:39 reconfigure /etc/ssh/sshd_config to accept root login and with empty password too Apr 03 09:38:51 reset root password to be empty Apr 03 09:41:07 i have no idea what happen now as in I tried to reflash it again Apr 03 09:41:37 and when i didnt insert the SD card, i get all the four LED lit solid Apr 03 09:41:49 and my compute cant detect the beaglebone Apr 03 09:41:54 computer* Apr 03 09:42:17 if i do insert the sd card, it remains the same and require password Apr 03 11:14:28 zene: you tried to reflash the board, right? Did you connect a power supply or did you connect it only via usb? Apr 03 12:07:18 hello Apr 03 12:09:16 hi all, what do i need to do in terms on linux changes in order to support 1GB ethernet with beaglebone black Apr 03 12:13:48 harel_: um, afaics you need a different phy on the bbb Apr 03 12:14:05 harel_: i.e. nothing in linux, but you need to modify the board Apr 03 12:15:44 how can that be? how does the linux "knows" that now it is working diffrently??? Apr 03 12:22:30 I suspect, given that 100M only needs 2 pairs it's not even wired up Apr 03 12:25:28 So do I need to change the linux package? or not? Apr 03 12:25:53 you can not fix it in software Apr 03 12:26:34 Yeah I understand I need to add the propery PHY, but do I need to change the linux device tree or anything else? Apr 03 12:29:40 That probably depends on which PHY you use Apr 03 12:32:59 Is there any guide for various PHY types? Apr 03 12:33:15 harel_: who's going to do the modification? Apr 03 12:33:36 What do you mean who? I should do this... Apr 03 12:33:54 you're confident with surface-mount rework?! Apr 03 12:34:08 I suspect it needs a PCB respin :> Apr 03 12:34:31 you have to remove modules from the board, and replace them .. and as I recall, the extra signals aren't brought out from the am335x processor to use it .. Apr 03 12:34:35 Ofcourse, we are building our own board, it is just based on the beaglebone black board. Apr 03 12:34:41 you're better off getting a different BB* board Apr 03 12:35:19 if you google the PHY on the BBB, there are some alternatives by the same supplier .. for example Apr 03 12:36:55 and with some splicing of the am335x TRM/Guide and the AppNotes from the PHY .. you should be able to work out what to do .. or you can 'borrow' the designs from one of the other beaglebone boards .. although the one I'm thinking of, not sure they published the schematics for the BB-Enhanced, which I know has Gb Eth on it Apr 03 12:41:55 So can i just "copy" the device tree section related to the Gb Ethernet from the BB-Enhanced and it should work? Apr 03 12:55:43 hello. We're planning to build a sort of LCD CAPE for a BBB, but with a lot more buttons (a keyboard with about 30 keys). The BBB will run a "kiosk" app to show production data obtained by RS232 (it will be a smooth, animated, nice visualization) . I'd like to ask what's the best method (for this purpose) to handle that keys.... we're evaluating if using a multiplexer connected via normal BBB GPIO, or using i2c to poll our "cape" keyb Apr 03 13:24:22 harel_: Who is responsible for the Linux BSP part (u-boot/device tree/kernel) of your own board? That person should already know such things. Apr 03 13:53:08 hey Apr 03 17:01:13 tbr: ver|laptop: just fyi, it needs a different phy + magnetics + connector, all required signals from the am335x are there (rgmii uses a subset of the mii pins), and SYSBOOT 6 and 7 need to be changed from pulldown to pullup Apr 03 17:02:26 zmatt: OK, good that I try to not get too much into the hw side and IF, then I actually go and read the fine datashites Apr 03 17:06:14 and you want a phy with "internal delay" since the am335x does not support this, otherwise you end up having to splice two feet of wire into the clock connection to realign it properly Apr 03 17:08:58 :D Apr 03 17:10:21 of course only a crazy person would do such a thing Apr 03 17:10:25 * zmatt points at ds2 Apr 03 17:10:27 ;) Apr 03 17:11:13 heh, yeah, the local crazies are well known ;) Apr 03 18:21:44 zmatt: I do recall -someone- trying it .. LOL Apr 03 18:21:53 but if you're doin a board spin .. its no big deal. **** BEGIN LOGGING AT Mon Apr 03 18:41:26 2017 **** ENDING LOGGING AT Tue Apr 04 03:00:01 2017
