**** BEGIN LOGGING AT Sun May 08 02:59:58 2016 May 08 13:10:38 anyone here is using bbb to 3d print? May 08 14:19:01 I think I crashed my beaglebone. I can't get it to boot anymore. When I set power (both USB or 5V) the power led goes on, bu nothing happens May 08 14:19:31 I can click on the reset or power down, nothing happens. Apart if I keep pushing the power button for 7s then the power led goes off. May 08 14:19:57 I tried booting from SD card (keep user button on when powering), but nothing more happens, only this lonely power led May 08 14:20:08 Anybody has an idea what I should tried ? May 08 14:25:43 Bobox: do you have a serial debug cable? you're kinda lost without it .. unless you got a clean freshly-written uSD card with a known good image on it .. May 08 14:26:50 That's what I found with web searches, I need a serial debug cable to have the low level information May 08 14:27:05 And I don't have one currently May 08 14:27:15 I will look for that May 08 14:27:32 Thanks veremit May 08 14:28:10 I have a feshly written usSD car with a good image on it, That I already used 2 days ago to upgrade the eMMc, but what can I do with it ? May 08 14:28:22 I can't seem to have the BBB boot from it May 08 14:29:25 insert the uSD, hold the BOOT button (next to uSD slot) down *whilst* you *power* the board (NOT reset) May 08 14:32:09 I have tried that, and just retried in case, but nothing more happens, only the power led highlights, nothing else. May 08 14:32:29 power led comes on steady .. it doesn't just blink once (briefly) ?! May 08 14:32:31 I think I really need this serial to usb to gie more information May 08 14:34:54 I suspect so .. May 08 14:35:56 I'll get that and come back here when I see what is the output on the serial. Thanks for the help veremit May 08 14:36:18 np May 08 15:31:38 hi, what kind of SD card for the BBB take? SDHC ? May 08 15:44:40 drgibbon: microSD, any. preferably one that is good at random IO May 08 15:51:39 ok thanks :) May 08 15:55:08 there are some very specific samsung models that are supposedly great May 08 15:55:27 and some other brands are known to be generally OK May 08 15:55:40 and never bother with Kingston, they source random crap May 08 15:56:42 the underlying problem is: cards get optimized for linear read/write, as in pictures, videos, bulk file transfer May 08 16:01:13 sandisk seems to be ok May 08 16:02:05 huge case of YMMV though .. I'ev used kingston with absolutely no issues on arm. May 08 16:03:31 veremit: kingston is hit and miss as they just buy whatever is cheap/available in terms of controllers and flash May 08 16:03:47 * tbr has had OKish results with transcend May 08 16:04:09 IIRC Arnd Bergmann did the original random-io benchmarking and recently someone updated that May 08 16:04:26 tbr: you're pretty much toast with any consumer item in that regard May 08 16:05:37 veremit: well, if it's in onesies or low volume, you can optimize a bit. e.g. that one line of samsung. If you need volume, it's a different story. May 08 16:06:50 tbr: did you see where that article is? May 08 16:07:09 * tbr goes to dig into his google+ May 08 16:09:58 "Indeed, it seems like much less has changed since I last looked at this a number of years ago: Samsung and Sandisk still have reasonable performance (and they make their own controllers and NAND chips), while many the third-party products (Kingston in particular, using Toshiba controllers like Sony did) are basically unusable for random I/O." May 08 16:11:21 https://www.reddit.com/r/chrubuntu/comments/1tyth0/what_are_the_fastest_sd_cards_for_dual_booting/ May 08 16:16:53 and you should probably use arnd's flashbench tool to see how well your card fares May 08 16:17:37 veremit: "Kingston still sucks. If you already installed using a Kingston card or anything whose oemid is 0x544D or 0x5048, you can throw that card away now and reinstall." May 08 16:20:39 where's that tool live/ May 08 16:23:40 "The tool that was used to do all measurements is available from git://git.linaro.org/people/arnd/flashbench.git." May 08 16:24:59 tbr: aha, ty May 08 16:39:13 tbr: update: http://git.linaro.org/people/arnd.bergmann/flashbench.git :] May 08 16:39:28 unless thats jut the web url .. but worth a bookmark May 08 16:39:28 ah :) May 08 16:39:54 ~seen rcn-ee May 08 16:40:14 took that url from an old LWN post, so no surprise it might have changed May 08 16:40:24 yea looks like th URLs changed a bit .. even in that page .. no probs May 08 16:40:31 citylight2: he hasn't been in for ages May 08 16:40:39 is there actually an active seen script in here?? May 08 16:41:03 I forgot where to see is kerenl commits to our kernel May 08 16:41:10 hmm DevaamoBot might, but I probably lobotomized it in here May 08 16:41:20 !seen rcn-ee May 08 16:41:59 I can dump an eggdrop n here with seen on it if anyone would find it useful May 08 16:42:05 rcn-ee was last seen in #beagle 8 weeks, 2 days, 18 hours, 45 minutes, and 21 seconds ago: maybe a bus stall? May 08 16:42:16 /msg DevaamoBot seen #beagle rcn-ee May 08 16:42:18 ah it pms May 08 16:42:28 coolio May 08 16:44:41 veremit, can you help me see which new commits are the new kernel? May 08 16:44:52 citylight2: mainline or beagle? May 08 16:44:58 beaglebone May 08 16:45:34 citylight2: https://github.com/beagleboard/kernel is the starting point .. May 08 16:45:36 which version? May 08 16:45:55 woops .. try /linux .. my bad .. not /kernel :D May 08 16:46:23 v4.4 last commit 3 days ago by RN May 08 20:59:48 hi there, i just bought a beagleboneblack, and was trying to set up a microsd card with a linux build May 08 21:00:25 thing is because sfdisk no longer supports CHS addressing - i cant format the disk as per any instructions i can find May 08 21:01:12 all the instructions seem to use either fdisk or sfdisk, which no longer work. Any advise on how to work around this? May 08 21:03:34 [from the man page of sfdisk] - sfdisk supports MBR (DOS), GPT, SUN and SGI disk labels, but no longer provides any functionality for CHS (Cylinder-Head-Sector) addressing. CHS has never been important for Linux, and this addressing concept does not make any sense for new devices. May 08 21:05:59 actually - ignore me - ive just realised fdisk works in expert mode May 08 21:06:07 its only sfdisk that doesn't work **** ENDING LOGGING AT Mon May 09 02:59:59 2016
