**** BEGIN LOGGING AT Fri Aug 15 03:00:00 2014 Aug 15 11:10:26 guys, what rcn kernels are you using on your bbb's ? I am still on 3.8.13 ones ! Aug 15 11:30:28 the TI descendant 3.8 kernel is still the most common Aug 15 11:31:11 you can boot mainline if you use one of the two known working defconfigs, but some things won't be available Aug 15 11:31:30 I think the latest trend is the armv7-multi defconfig or such Aug 15 11:58:30 HI, can anybody help me how to upgrade automake on debian? Aug 15 17:51:43 Hello, is anyone online here? I'm new to the BeagleBoneBlac (I have RevB6 + Debian 7 Wheezy) Aug 15 17:51:48 black* Aug 15 17:52:17 I've run into, what I can only describe as a bug in the ls program, and would like to see if other users experience the same issue... Aug 15 17:52:35 (while at the CLI over SSH of course) Aug 15 17:53:56 I have Googled for the issue, read the man page, tested, etc Aug 15 17:54:13 I have created a folder "~/folder/pythonsecret" Aug 15 17:54:21 I go into ~/folder/ Aug 15 17:54:30 and I type "ls -l python*/" Aug 15 17:54:47 and ls does NOT list the pythonsecret folder as it normally would Aug 15 17:55:12 I've tried different syntax and experimented for some time, all to no avail. Aug 15 17:57:36 Interesting. Aug 15 17:58:15 What is the output of `echo $SHELL`? Aug 15 18:28:36 Hi, I was wondering if anyone has experience using the BBB's GPIO as a parallel port. Thus far, it seems like the GPIO bits are a bit scattered over P8/P9 headers with few memory contiguous pins. For performance reasons, I'd prefer to be able to write a whole word to GPIO without concatenating individual bits. Aug 15 18:42:26 sheridp: Are you trying to do this from userspace or the PRU? Aug 15 18:42:46 Because the PRU is probably the right option if you are concerned about performance. Aug 15 18:43:38 agmlego: Either is fine. Right now I'm using an mmap for ease of programming, but I can move it to the PRU for performance Aug 15 18:45:01 What kind of performance are you looking for from the application? Have you tested the solution and found it lacking? Aug 15 18:49:50 I need to clock in an ADC's 12bit output at around 5MHz, the faster the better Aug 15 18:51:49 Part of the problem though, is that there are actually 2 ADCs, each with 12bit output. I only need to read 1 at a time (different stages in the algorithm), but they are not multiplexed (not my design). So essentially, I need two parallel ports that are 12 bits wide. Aug 15 18:53:07 I've made a table that organizes the P8 and P9 headers by GPIO bank and bit number: there is one run of 17 contiguous bits, and a few runs of 8bits Aug 15 18:54:36 Maybe at 200Mhz PRU, cat-ing a couple 8bits won't be so bad. Aug 15 18:56:11 Hi Friends! I've got a BBB with the Linux arm 3.8.13-bone63 and I'm trying to update the kernel to the beta with ./update_kernel.sh --beta-kernel but bootup is stopped at Starting kernel ... Aug 15 18:56:17 Is this expected? Aug 15 19:01:20 sheridp: I think you are going to find yourself in trouble using the PRU then. Aug 15 19:02:59 sheridp: Could you maybe just use a shift register to grab the parallel bus and make it serial? Seems like a faster way to do things. Aug 15 19:04:20 sheridp: But honestly, the best way to figure out if you need to optimise something, is to try it the naive way first and see if it is too slow. Aug 15 19:06:25 agmlego: lol, why is that? I came here thinking I was in trouble, but changed my mind on the PRU approach. @ 200MHz, 2 instructions to grab the data, 1 instruction to shift, 1 to cat, and 1 to store for DMA. Even if I'm off by a factor of 10, I'm at 4Mhz Aug 15 19:07:39 (assuming that PRU can grab a whole GPIO register) Aug 15 19:11:47 I'm back...echo $SHELL gives me /bin/bash Aug 15 19:11:50 sheridp: THat is where my knowledge on the PRU breaks down; not sure there is a single-cycle instruction to grab a GPIO register as a whole. Aug 15 19:12:05 I've also posted the issue I've been having on DaniWeb....no response yet: http://www.daniweb.com/software-development/shell-scripting/threads/483411/debian-7-wheezy-ls-not-acting-as-expected Aug 15 19:12:16 John__: OK, then you need to file a bug the usual way with the bash maintainers on Debian armhf. Aug 15 19:28:29 hai Aug 15 19:28:59 i have a new beaglebone black board Aug 15 19:29:20 i am unable to boot the device Aug 15 19:30:01 only power LED is on after power supply and no 4 LEDS are glowing Aug 15 19:30:09 What is the problem Aug 16 00:37:21 sigh...ubuntu is such an abomination Aug 16 00:37:39 hahaha Aug 16 00:40:07 give me a text command line! Aug 16 00:45:14 their package management is broken beyond belief Aug 16 00:45:19 and this is on x86 Aug 16 00:46:57 what's borken? Aug 16 00:50:25 everything Aug 16 00:50:34 apt-get tries to download nonexistant packages Aug 16 00:55:38 oh and this is AFTER a apt-get update Aug 16 00:55:44 broken ass garbage **** ENDING LOGGING AT Sat Aug 16 02:59:58 2014
