[beagleboard] Setting the CPU speed.
I've been looking at the speed of my BBB and not really understanding what's going on. The files under /sys/devices/system/cpu/cpu0/cpufreq show that the performance governor is in use, but the speed is a constant 550,000 whatever the load. The scaling_setspeed unsupported entry probably reflects this; does anyone know how I set up a kernel to handle the BBB's CPU speed control?

Re: [beagleboard] Re: QNX on BBB
Well that was my point in my previous comment. Whereas I think QNX is a really great RTOS hopefully brigded to opensource -whereas being closed source- in recent years (yes recent compared to 20 years of existence) , from the start I've believed in the µKernel architecture as the best one.

Honestly, I really like to use QNX on BBB but strongly believe that if it's not on Raspberry it won't be ported to BBB neither. 2014-03-14 10:40 GMT+01:00 Thorsten Gonschior tgonsch...@spectral-process.com: NEWS: - Show stopper - After clearing up some technical aspects I ran into a major show stopper.

Re: [beagleboard] Re: QNX on BBB
quote: Seems not so obvious. So QNX has an opensource part but for BBB it implies these steps ... hm, ok sry I must have missed your point :) I agree that QNX is probably the best choice for a robust and well designet real time embedded system. In this I do not bother the OS-price or royalty which probably is scalable. Texas Instruments learned this 10 or 15 Years ago when the Code Composer Studio was very expensive and a simple JTAG Pod cost 3.000,-. Even Microsoft pushes the development platforms for free into the market, because all of them understand that the major market is selling the operating system (in case of Microsoft) or selling the hardware (in case of TI) and not selling the development solutions. See XILINX, development studio incuding simulator for free. This is what makes people work with it. Expecting 10.000,- as entry cost is the best guaranty to avoid thousands of developers working with QNX and thereby hundreds of thousands licences of the OS. I dont understand this philosophy 20 Years of experience as embedded developer showed me on thing. 1.000,- eur or $ ist the magic barrier. this is what people invest as an attempt for some half cooked idea thy have. Max be that 95 % of those ideas will never reach any state of economic asset, but once in a while it will and it will do with power. suppressing this kind of innovative forces is hurting the provider itself.

Hi Robert, I had connected a USB camera to the beagle XM board running ubuntu and it worked successfully( tested with camorama application). I applied this patch https://github.com/RobertCNelson/stable-kernel/blob/v3.4.x/patches/omap_fixes/0001-Fix-sprz319-erratum-2.1.patchas I was facing the same issue with low temperature. After applying the patch, the board works fine at low temperatures but the camera output flickers using the camorama application. The version of ubuntu image used is 3.4.7-x1 Are there any other patches to handle this problem?

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
Robert, thanks for your work. Is there a guide somewhere to build or a way to download a absolute minimal image. Something with only ssh, apt and full hardware initialization on it and nothing else. That would be a good base for couple of headless projects I am thinking about. When I am talking about HW initialization I am only thinking about network and hwrng Right now I am using this: http://rcn-ee.net/deb/flasher/wheezy/BBB-eMMC-flasher-debian-7.4-2014-02-16-2gb.img.xz and I will continue to use it as it is. But if you plan to stop developing those images I need to start thinking about another way to get a headless emmc debian image working.

It's kind of strange that the BBB's default kernel does not even have PREEMPT activated. Such a board doesn't fit to many embedded applications where we need at least some kind of determinism. It is even worse, that nobody seems to care about this problem. Contrary to that, the Raspberry PI's standard kernel has PREEMPT activacted from the very beginning. I have tested Robert Nelsons kernel 3.8.13-r9 ( https://github.com/beagleboard/kernel/tree/3.8-rt). It does not have PREEMPT_RT activated by default. When doing so, it does not boot. But activating PREEMPT does work. However, development of this branch has stopped several months ago. The official source for RT Linux (3.8.13) has evolved since then. Meanwhile there's an rt17 patch set ( https://www.kernel.org/pub/linux/kernel/projects/rt/3.8/). Did anybody give this a try?

It seems to me that if Debian is going to replace Angstrom, then a link to the Debian release images and FAQs should be put there. Eventually, the Angstrom info could be deprecated, or rather archived and its visibility reduced. It seems to me that there are currently too many places to go to get the various linux distributions and kernels, and none of them seem to be officially sanctioned as the standard release. This leads to unnecessary confusion for new users. Some info on beagleboard.org, some info at circuitco.com, some info at elinux.org, some info at armhf.com, etc., not to mention all the other stuff at ti.com. The official wiki at http://www.elinux.org/Beagleboard:BeagleBoneBlack#Software_Resourcesdoesn't even mention this Debian releases (and it should if you want people to test it). The community wiki at http://elinux.org/BeagleBone_Community#Debian does list a Debian release, but it is a different, and incompatible, arm EABI version from this new armhf release.

[beagleboard] Ethernet interface failure
The BeagleBone Black ethernet interface will fail after a few hours of operation. As an example, we did a fresh install of both Debian and Ubuntu on two Beagles (Newest updates for the Arm OS), connected them to the network and sure enough the next morning, both of the interfaces had failed. Several people have apparently noticed this issue, but I can't find any suggestions on possible fixes. It appears to potentially be a hardware or Kernel issue.

[beagleboard] BBB UVC/DMA crash kernel 3.13.6-bone7.1
The USB DMA still appears to have problems when used with USB cameras. It appears that whenever I attempt to issue controls via UVC to a camera that is capturing, then I get the attached crash. PIO mode works fine. Could I suggest that the default defconfig selects PIO mode until DMA mode works reliably? I hope this is the right place to post. If not, please excuse my intrusion, and suggest another.

I moved that section from my .profile to .bashrc since .profile will source .bashrc if it exists. So a login shell will source .profile, which will source .bashrc and add the path. A non login shell will source .bashrc directly and add the path. This seems to work for me. I'm not sure what happens for script that use #!/bin/sh since that runs dash instead of bash. The dash docs say it sources .profile on login shells so that should be OK, but for non login shells it says it looks in the ENV environment variable for the name of a file to execute. There is no such variable defined currently so it does nothing. Perhaps these commands should be put in a .shinit file and then set ENV=$HOME/.shint in the .profile file to take card of setting it for login shells, and have the .bashrc source this .shinit file for non login shells.

Re: [beagleboard] BBXM and SGX libs
I had not tried the demos besides the ones that reside in the same directory as the blit test. I decided to give EvilSkull a shot on my board. I noticed however that the instructions on http://elinux.org/index.php?title=BeagleBoardUbuntuoldid=314498#SGX_Video_Acceleration are not 100% correct. Specifically the step after running the blit test. Wiki says: tar xf GFX_Linux_SDK.tar.gz cd GFX_Linux_SDK tar xf OGLES.tar.gz I had to do: tar xf GFX_Linux_4.08.00.02_examples.tar.gz cd GFX_Linux_SDK tar xf OGLES.tar.gz From there I was able to run: /opt/sgx/GFX_Linux_SDK/OGLES/SDKPackage/Binaries/Raw/Demos/EvilSkull/OGLESEvilSkull Keep in mind that I ran the RAW version. I have no idea what that will do under X11. I don't have xorg installed so I cannot validate that the X11 version of EvilSkull actually works. I am running Ubuntu 11.10.

Robert, your timezone is fine for me. I am actually AZ time myself, but really simple to change via dpkg-reconfigure tzdata. Also, as for how to change some default stuff, perhaps have a web page ( html file, or maybe even a node.js thing to make it more dynamic ? ) Dennis, just so you know, you should be able to google debian + whatever keyword you need to know something about to find an answer. We're talking basic Linux / Debian stuff here. For example. google - howto change debian timezone, and you will very likely find what i asked about last night dpkg-reconfigure tzdata. Anyway, dont feel as though I am putting you down by saying this. quite the contrary actually. As I have been using Debian since the 90's and have to google many things.

Sorry, I felt i was not clear in my last post . . . *Also, as for how to change some default stuff, perhaps have a web page ( html file, or maybe even a node.js thing to make it more dynamic ? )* What I mean by the above, is have an information web page on how to do various things, like how to set time zone etc. Perhaps as part of the getting started page thats already on the BBB. Even though I think Debian is one of the better distro's out there because of the fact you can simply google the answer to your questions( just one aspect actually ) I feel that having a web page linked to from the getting started page on how to change all teh default basic stuff would be super helpful for new users.

Re: [beagleboard] Re: Kernel panic - not syncing: No init found. Try passing init= option to kernel.
NFS root as done on ARCH, Debian, and busybox will not work the same way on
ubuntu. Nor fedora or Angstrom for that matter. What you need to do is find
a how to for netbooting Ubuntu ( PC ) and adapt it.
obviously going by the error messages above, this configuration does not
like your initial ramdisk ( initrd ) for some reason.

hai all,
can anybody help me how to boot the rootfs using nfs ..still i stuck
with same issue..
currently i'm using ubuntu13.10 as a host pc to implement nfs booting.
i referred the following link to build the kernel
http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel
http://elinux.org/Building_BBB_Kernel
I attached my uEnv.txt file I use for NFS. Make sure you change the IP
address and userID for nfsroot to match your host IP and userID. My local
network uses an address 10.100.116.xxx. My BBB is 10.100.116.104 and my
host is 10.100.116.73.
You need to install nfs-kernel-server on your Ubuntu host
Add the following line to your /etc/exports file on your host
/home/userID/targetNFS
Re: [beagleboard] Setting the CPU speed.
Honestly unless you have a specific reason I think the default ( ondemand ) governor is probably the best. While idle for me the CPU has always been 300Mhz, and with a heavy load ( over 60% load ) the CPU goes up to 1Ghz.

Adding the -l make it a login shell, so it sources /etc/profile and then .profile, which sources .bashrc if it exists. Without this change lxterminal runs bash as a non login shell so it sources /etc/bash.bashrc and then .bashrc instead. The /etc/bash.bashrc file setups the command prompt. What I don't understand is why an lxterminal command with no options starts a bash shell, but an lxterminal -l command starts a /bin/sh shell which is actually a dash shell. You end up with no command prompt because it doesn't run /etc/bash.bashrc. There are probably other differences. This is why you added the -e bash option. Anyway this does seem like a better fix, though anything that runs /bin/sh will still have a different PATH without the user bin directory.

Adding the -l make it a login shell, so it sources /etc/profile and then .profile, which sources .bashrc if it exists. Without this change lxterminal runs bash as a non login shell so it sources /etc/bash.bashrc and then .bashrc instead. The /etc/bash.bashrc file setups the command prompt. What I don't understand is why an lxterminal command with no options starts a bash shell, but an lxterminal -l command starts a /bin/sh shell which is actually a dash shell. You end up with no command prompt because it doesn't run /etc/bash.bashrc. There are probably other differences. This is why you added the -e bash option. Anyway this does seem like a better fix, though anything that runs /bin/sh will still have a different PATH without the user bin directory.

Try passing init= option to kernel.
NFS root as done on ARCH, Debian, and busybox will not work the same way on
ubuntu. Nor fedora or Angstrom for that matter. What you need to do is find a
how to for netbooting Ubuntu ( PC ) and adapt it.
obviously going by the error messages above, this configuration does not like
your initial ramdisk ( initrd ) for some reason.
NFS booting is not compatible with Initrd. Thus the kernel must be built
without Initrd configured and uenvcmd has a dash instead of an Initrd memory
load address.

Re: [beagleboard] Re: Kernel panic - not syncing: No init found. Try passing init= option to kernel.
I build linux Linux systems that run on their inital RAM disk
and I can NFS boot them, so I don't think the kernel haveing
initrd capability does anything wrong.
Maybe I missed something in the thread, but why are
you using /lib/modules/3.8.13/init ??
When I see this
Kernel panic - not syncing: No init found. Try
passing init= option to kernel.
message it is because the /sbin/init program the kernel
tries to run is missing a dynamic dependency. This sort
of thing happens when you build a whole (small) system
from scratch.
Try using init=/bin/bash just to see if it runs. If so,
it isn't an NFS root problem per se, is is a problem
with the program you are using for init.
