**** BEGIN LOGGING AT Tue Jan 05 02:59:58 2016 Jan 05 03:04:47 Is there a range of supply voltage or is it just 5V? Jan 05 03:20:06 3.3Vdc is more common today for digital... also 2.4 and 1.8 are used a lot Jan 05 03:20:35 Usually, 5Vdc is dead except among hobbyists and vintage restorations. Jan 05 03:20:53 3.3V is the new 5V Jan 05 03:21:13 Dispite Arduino owner opinions Jan 05 03:59:26 Despite Jan 05 04:25:33 zmatt: ? Jan 05 04:43:03 when i try to disassemble at 402f0400, i get this nasty-sounding message from CCS V6.1.2: http://ur1.ca/ods5l -> http://paste.fedoraproject.org/307192/45196893 Jan 05 04:43:27 any idea why? Jan 05 04:43:57 i'm also using an XDS100V2 debugger, if it's relevent. Jan 05 04:44:19 this is sram - it should always be available, right? Jan 05 04:44:37 internal sram, i.e. Jan 05 12:12:19 argh, yates _really_ needs to leave his irc connected so I can actually answer his questions Jan 05 12:22:18 or answer them and we'll point him at the logs later :) Jan 05 12:23:44 ohh, good one, although it'll feel odd to address someone who isn't here XD Jan 05 12:24:16 yates: 0x208D0 is internal ROM, not internal SRAM, if you tried to write to it then a bus error will indeed ensue Jan 05 12:25:15 yates: CCS makes _every_ error sound dire, pick a few random possible underlying causes (generally none of which the actual one) and things to try to fix the problem (none of which will help) Jan 05 12:26:04 yates: so basically an error from CCS should be interpreted as "Something wrong!! I don't understand!! Halp!!!" regardless of the error message Jan 05 12:29:25 yates: the initial vector table (and hence the reset vector) is at adddress 0, which is aliased to 0x40000000 which is where the 176 KB of internal ROM resides Jan 05 12:30:19 the first 128 KB is accessible by secure world only, the 48 KB of public ROM starts at 0x20000 (== 0x40020000) Jan 05 12:31:26 this is also the entrypoint of public ROM, and if you try to attach to the Cortex-A8 during reset then this is where it will halt, since you do not have permission to halt it while executing in secure world Jan 05 12:34:16 for more details on the memory map, check my spreadsheet https://goo.gl/UHF2Fy ... the HASS tab shows the local routes within the cortex-A8 subsystem Jan 05 12:39:25 when trying to disassemble your program at 0x402f0400, make sure it's actually been loaded by public ROM by setting a hardware breakpoint there Jan 05 12:39:43 and load symbols (Debug -> Load -> Load symbols, point to your ELF file) Jan 05 12:40:44 also, if CCS has not been given a memory map, it may try to access addresses below 0x402f0400 and get a bus error on that Jan 05 12:43:49 znc ftw .. or there are other irc bouncers out there. He's not a web irc user, thankfully. Although there is another option for synchronisation. Jan 05 12:44:19 screen + irssi or some other text-mode client? :P Jan 05 12:45:04 yates: the memory map is normally supplied by the GEL file btw Jan 05 12:48:47 yates: it can load ELF files just fine btw, it just expects the .out suffix but you can change that in the popup to list *.* and it'll take an elf file with any suffix Jan 05 12:50:02 yates: I recommend letting public ROM load your executable however, since otherwise you may need to do more initialization and disable the watchdog, things which public ROM normally does for you Jan 05 12:52:29 yates: a _hardware_ breakpoint can be used to catch the jump from pubrom to your code, and you can load symbols either before or after Jan 05 12:53:41 without symbols CCS does not know whether to disassemble in ARM or Thumb mode (it is incapable of using the Thumb-bit of CPSR as a hint for disassembling code at PC...) Jan 05 13:00:28 if you do intend to try to upload a program via JTAG, beware that CCS by default sets PC to 'main' rather than the entrypoint of the ELF file, you need to change that in the debug settings... but in any case it is incapable of using the entrypoint stated in the ELF header, you need to specify a symbol (e.g. _start) or an address Jan 05 13:03:34 tbr: that should do for now :) Jan 05 13:03:39 :) Jan 05 13:04:26 I might just dig up some preconfigured CCS project since that's easier than explaining all the things that need to be configured right to be make CCS behave in a moderately sane way Jan 05 15:08:13 I am experiencing a power issue with all 3 of my BeagleBone Blacks. When I connect the usb power cable and when I press the power button, the power LED flashes on but will not remain on. Does anybody have any experience with this? Thanks Jan 05 15:14:34 you shuoldn't need to press the power button at all .. soon as the board is connected via usb (the mini-B port, NOT the A) it should boot Jan 05 15:14:42 needhelp596, ^^ Jan 05 15:18:00 I am very new to this board, so please bear with me. I attempted to follow the getting started guide but was unable to use chrome to browse the device nor was I able to get the power to remain on. Jan 05 15:19:05 I was using a usb to mini-usb cable to power the board from my laptop Jan 05 15:35:11 i suggest trying a different usb port although i doubt a laptop usb port would be that limited in current although i have hear of it Jan 05 15:35:13 I have had the same problem getting the board to boot off of usb, DC connector boots up fine so i didnt worry about it. only seemed to happen after flashing a new image on the emmc. Jan 05 15:45:55 DC barrel is recommended, as is RJ45 ethernet. Jan 05 15:46:12 the USB 'magic' is fine when it works .. but its quite temperamental Jan 05 18:09:33 hello guys i have just plugged in my beaglebine black, power led is shining but there is no image in my monitors??? Jan 05 18:09:51 are the other lights doing anything? Jan 05 18:10:16 only power led Jan 05 18:10:32 thats not good. Does it have enough power Jan 05 18:10:43 just plugged in 5V DC Jan 05 18:10:50 check the amps Jan 05 18:11:00 though really that should be okay... Jan 05 18:11:22 sorry what is amps meaning? Jan 05 18:11:44 amps are the flow of power (current) Jan 05 18:12:07 Volts = amps * resistance Jan 05 18:12:17 the charger should say Jan 05 18:12:43 sometimes the bbb wont start and you just have to try a reboot Jan 05 18:12:59 so should i push the reboot button Jan 05 18:13:00 ? Jan 05 18:13:10 Try, or just unplug replug Jan 05 18:13:38 both not working Jan 05 18:13:53 try it without anything else plugged in Jan 05 18:13:56 the problem is i just worked with bbb 2 hours before Jan 05 18:14:07 did you flash it? Jan 05 18:14:28 wanted do to but not yet Jan 05 18:14:39 does the sd have an image on it? Jan 05 18:15:01 on my sd card there is ubuntu image but i didnt insert it yet Jan 05 18:16:07 could it be that i just have written a command and thatwhy i am not getting any siganl on my monitor# Jan 05 18:16:23 well, lets try doing that. You may have to hold the boot button Jan 05 18:16:50 ok for couple of seconds? and inserd sd or noT? Jan 05 18:17:19 *insert Jan 05 18:19:35 sry dude Jan 05 18:19:47 but afterwards i have to do what? Jan 05 18:20:21 I think you may have to hold the boot button to boot from the sd. Not too sure though Jan 05 18:20:30 I have to shower though. Gl mate Jan 05 18:32:41 mates could you help me? Jan 05 18:33:46 anyone know why beaglebone is giving no image? Jan 05 18:34:10 plugged 5VDC and hdmi cable Jan 05 18:34:11 ? Jan 05 19:12:13 rcn-ee: managed to get bbx15 enabled in debian's experimental kernel Jan 05 19:12:23 vagrantc, nice! Jan 05 19:12:56 rcn-ee: though eSATA and USB weren't working, last i tried ... not sure if i'm missing some config options, or if there are some patches needing mainline support Jan 05 19:13:24 also, haven't tested since 4.4-rc6, maybe -rc8 has magically fixed things Jan 05 19:13:25 eSata is powered via usb.. Jan 05 19:13:31 usb needs extcon... Jan 05 19:13:58 yeah, i suspected it was a chain of options that might not have been enabled Jan 05 19:14:45 it's DWC3... Jan 05 19:15:23 * vagrantc feared the "only works as a built-in" Jan 05 19:15:30 but i didn't get around to testing that Jan 05 19:15:39 it should work as a module... Jan 05 19:16:07 yeah, just with the BBB that was a problem for a while, and i just encountered it on the orangepiplus2 Jan 05 19:16:23 so it's my first hunch :) Jan 05 19:18:32 you guys enabled: CONFIG_PCI_DRA7XX=y (the module option is going to be removed. ;) ) Jan 05 19:19:06 i think all the PCI features are =y Jan 05 19:20:02 have you tried modprobign: CONFIG_USB_DWC3_OMAP=m Jan 05 19:20:02 looks like the config ended up with: CONFIG_USB_DWC3=m Jan 05 19:20:03 CONFIG_USB_DWC3_HOST=y Jan 05 19:20:03 CONFIG_USB_DWC3_OMAP=m Jan 05 19:20:03 CONFIG_USB_DWC3_EXYNOS=m Jan 05 19:20:21 you can also enable: CONFIG_USB_DWC3_DUAL_ROLE Jan 05 19:20:55 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/am57xx-beagle-x15.dts?id=refs/tags/v4.4-rc8#n711 Jan 05 19:22:07 there it is: # CONFIG_EXTCON_USB_GPIO is not set Jan 05 19:22:09 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/am57xx-beagle-x15.dts?id=refs/tags/v4.4-rc8#n103 Jan 05 19:22:16 http://lxr.free-electrons.com/source/drivers/extcon/Kconfig#L113 Jan 05 19:22:30 so.. + CONFIG_USB_DWC3_DUAL_ROLE + CONFIG_EXTCON_USB_GPIO ;) Jan 05 19:23:23 looks like i'll be compiling kernels again :) Jan 05 19:26:58 just two more modules. ;) Jan 05 19:27:35 i don't see anything else that really sticks out. ;) Jan 05 19:27:54 oops set CONFIG_SENSORS_GPIO_FAN Jan 05 19:28:18 you have tmp102 enabled, but we need gpio_fan to trigger the "gpio" for fan-on.. Jan 05 19:28:24 so 3 modues. ;) Jan 05 19:28:59 that's for the on-board powered fan? Jan 05 19:29:37 i've been running it in an unheated space, but it gets warm to the touch even idling Jan 05 19:29:51 yeah connector "j1" allows a fan hookup.. Jan 05 19:30:10 but i think before i start adding it to the compile farm, i'll probably want a fan Jan 05 19:30:21 it's not populated by default.. but it's nice to have.. (it'll thermal down-clock on it's own).. Jan 05 19:32:18 vagrantc, i'm using : https://www.digikey.com/product-search/en?keywords=%20COPAL%20F251R-05LB (or you can find it on old video cards) we should have a "kit" with the connector at soem point.. Jan 05 19:33:24 kit would be nice :) Jan 05 19:33:57 although i have a few old video cards i could probably scavenge :) Jan 05 19:46:19 given how long it took the bbx15 to come it, it sure is a shame it didn't come with 4GB of ram Jan 05 19:55:03 rcn-ee: ok, building a kernel with those options enabled, and they actually took this time Jan 05 19:55:54 i think i tried enabling some or all of those at some point past, but there were probably missing dependencies, or boolean-only and i tried to enable as modules Jan 05 19:56:22 back in the day, it would silently change =m to =y if it was a boolean... not it just seems to disable them :/ Jan 05 19:56:27 now Jan 05 19:56:44 yeah, eveything is so interdependent now. ;) Jan 05 19:59:02 vagrantc, last month, i had a lot of fun when you guys moved usb to m.. my delta is based off your config, so i had to re-figure out how to force usb to built-in .;) Jan 05 20:02:06 i know it's maybe a pipe-dream, but hope to someday see a delta of 0 lines. Jan 05 20:03:11 it's getting closer.. but then i'm also dealing with "capemanager" bugs/hacks... (some will work as modules, some need to be built-in..) Jan 05 20:04:03 but dra7 enable with pull a chunk of that out. ;) Jan 05 21:37:10 I wonder why they still define iosets, I'd expect that with iodelay you could align any bunch of signals Jan 05 22:44:59 rcn-ee: well, that got USB working, but eSATA is still having issues Jan 05 22:46:04 ahci 4a140000.sata: couldn't get PHY in node sata: -517 Jan 05 22:46:54 i'm thinking ... CONFIG_TI_PIPE3 Jan 05 22:47:00 (obvious name) Jan 05 22:47:23 lsmod | grep -i pipe3 Jan 05 22:47:23 phy_ti_pipe3 5641 2 Jan 05 22:47:23 phy_omap_control 4217 2 phy_ti_pipe3,phy_omap_usb2 Jan 05 22:47:44 okay that's good then.. Jan 05 22:47:47 i'm going to try without the USB disk conncected Jan 05 22:48:02 to make sure the errors i'm seeing are only relevent for that disk Jan 05 22:49:25 the ssd claims to require 1amp ... but i've never observed it using that much Jan 05 22:50:18 [ 58.899241] ata1: limiting SATA link speed to 1.5 Gbps Jan 05 22:50:19 [ 58.899251] ata1: hard resetting link Jan 05 22:50:19 [ 63.902112] ata1: softreset failed (1st FIS failed) Jan 05 22:50:27 that sounds like it could be power constraints Jan 05 22:51:33 might be... do you have another ssd? (which model are you trying right now) Jan 05 22:52:01 yeah, i'm trying the one recognized via usb, which claims to only be .5 amp Jan 05 22:52:13 rcn-ee: el-cheapo "faspeed" Jan 05 22:52:30 rcn-ee: and el-cheapo "kingfast" is the .5amp Jan 05 22:52:50 the lower amperage one seems to behave the same Jan 05 22:53:06 * vagrantc wonders about external power Jan 05 22:54:12 unfortunately, don't have the right adapters to try external power at the moment Jan 05 22:54:32 well, working USB is huge progress Jan 05 22:56:42 i guess i could try a third ssd Jan 05 22:56:55 although this one claims to require 1.5amp Jan 05 22:57:10 * vagrantc wonders what these SSDs are doing with all those amps Jan 05 22:57:41 when i've monitored ower consumption, none of them have come close to more than .3amp Jan 05 22:59:23 i guess it could be a bad cable Jan 05 22:59:32 well, no, works fine with rcn-ee's kernel Jan 05 23:00:27 same difference Jan 05 23:00:48 i also have a lot more built-in... it could be a hidden dependicy... Jan 05 23:01:07 * vagrantc nods Jan 05 23:01:17 and maybe sata isn't fixed on mainline yet.. i think we had some external patches in 4.1.x-ti.. Jan 05 23:01:25 (although mainline sata works on omap5_uevm) Jan 05 23:05:36 well, step by step, will get it enabled in stretch eventually Jan 05 23:08:48 and by the time the board get's released.. ;) it'll work out of the box. ;) Jan 05 23:09:47 rcn-ee: by then, you could be living on a boat ;) Jan 05 23:10:22 as long as it's bigger than the box ds2. ;) Jan 05 23:11:28 but you could washed down to NO Jan 05 23:11:41 aren't you guys getting part of that massive deludge? Jan 05 23:14:28 ds2, thanks to el nino, we've have a very warm and no snow winter so far... (could almost say a drought.) Jan 05 23:14:52 * vagrantc has been covered in snow and ice for the last couple days Jan 05 23:14:53 the stuff we did get, we got about 3 weeks ago.. Jan 05 23:15:09 which is rare for the pacific northwest at this altitude Jan 05 23:15:53 all that stuff is heading south of us... ;) Jan 05 23:22:36 it was a warm balmy 15 F out today. or -10 for C people.

Jan 06 00:30:14 Anyone know where on earth I can get hold of a Roseapple Pi to ship to US/Europe? Jan 06 00:31:05 All the asian sites are either in Chinese/Singaporean etc and none seem to ship, but guys on YT have somehow gotten hold of them...I'm well stumped Jan 06 00:32:10 ?
