I felt bad about my post but over the next few days I came to the same conclusion. I think it's a security hole. Then it dawned on me that busybox is providing the commands but for Angstrom not everything is supported and finding out what works and what doesn't is an easter egg hunt. Finally in the process of searching on-line for help I came across this re Linux security http://www.tldp.org/HOWTO/Security-Quickstart-Redhat-HOWTO/appendix.html. This is what triggered my angst.

[beagleboard] BBB re-flash
Hello all, I was working with my BBB the other day and I was trying to get an OS other than Angstrom on it and I accidentally wrote the ubuntu img over the 73mb partition that shows up with BBB is plugged in. I have gathered that this is the boot partition and it seems right because when I try to boot it without an SD card the user lights never come on. So I DDed the angstrom re flash image to an SD card to attempt to fix it but all four lights never come on to signify the re flash process is done and I've done this several times giving it a couple hours a try. Right now as I stare at it the left light does a double flash once per second and the third one flashes a bunch kinda sporadically. I read somewhere that you can't plug ANYTHING into it or else it will just boot up which i hope isn't true because all I have to power it is a USB cable and I tried a cell phone charger with it to no avail. When I fdisk -l the 73MB partition does come up but has zero partitions. Does the reflash image not restore this? How do I restore this if not? Lastly the very beginning of this was I was trying to install TTYLinux. Is there a tutorial for installing TTYLinux to BBB? I tried simply extracting the contents of the tar to my SD card but that didn't seem to work. Not sure what other variables might have been mucking up that test at that point though. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Hi, there was a problem with a corrupt key file on the Angstrom image that prevented SSH from working. Not sure if that's still the case with new boards, but if you search this group for 'unable to ssh' (or similar) there is a cloud9 script to fix it from the web interface.

Regards, Gibson On Friday, December 28, 2012 9:00:51 PM UTC+5:30, steve.ch...@googlemail.com wrote: Hi This post concerns the process for setting up Eclipse Juno Remote Debugging on the Beaglebone I have been following the instructions given by Jan Alexson on her site http://www.lvr.com/eclipse5.htm. However there appears to-be some change in the latest version of Eclipse (Juno) compared with what Jan based her work on. In Juno some of the plugins she references don't exist in the download list. *C/C++ DSF GDB Debugger Integration *is a particular plugin of note. I convinced myself that Juno incorporated this and this was the reason the plugin was not visible, however it would be nice to have this confirmed. The frustrating thing is that binary is successfully built and loaded into the beaglebone, however the step that is meant to modify file permissions isn't being run. The step in question is chmod 777, hence the execution permission is not set on the Beaglebone. Also the destination location on the Beagle isn't /bin which makes me a little suspicious. As if I manually move the file there (/bin) and change its permissions, to executable, it works fine. The error message that I get from eclipse isn't very helpful, and a little inaccurate is the file is uploaded ok, it outputs: Error during file upload. Operation failed. File system input or output error Operation failed. File system input or output error Operation failed. File system input or output error I found the log file generated by eclipse which located in the workspace/.metadata directory and this isn't much help either. Gives the same output as above plus the java exceptions that caused it. However I do need to analyses it more detail. 1) Can anyone give me the processes that should be running on the Beaglebone to support the debugging session that is running from Eclipse on the host pc. 2) Can anyone tell me what plugins Juno should have.

I had only clicked through a couple of those links when I found I needed to register with them. So I guess you were able to register and get an account but you're saying those links are server 404 errors? That should probably be brought up with their webmaster and/or posted to another forum regarding the forum support and not technical support as in QNX tech support. It would be quite strange that they would link to download images and not have functioning images available. regarding QNX I wonder in what situation they are at all currently. After being sold to RIM ist there still interest in other embedded market, than automotive and mobile communication? This may be the only thing they will have left of value as their phone/communicator business faulters. IIRC I saw an automotive control system vendor state they were going to QNX. It does have a market. Several emails to sales for quotes and services for technical issues are not been responded. if the question was if they support the BeagleBone and they don't know their links and support pages are non-functional then they might be swamped with other technical issues instead of thinking they just need to point out they have pages stating the support is there. As you stated your question in this forum and how quickly I found that they state specifically supporting Beaglebone I wondered what 'work' you really did to find the answer. It looked pretty obvious there was support.

This is a bit embarrassing, but here it goes. I got myself a BBB because I want to switch from using MCS-51 processors and the like. I have no formal schooling in processors or electronics. I started working on processors around 1980 when I got hold of an Ohio scientific and later an AppleII+. Later moved to Z80/Z8000/8086/68030 and similar as I started to formally design HW and SW for embedded systems. Never had to bother even with C so have been hacking merrily away with Assembly only. Rarely adding ( with difficulty) bits of code for floating point when my own extended math routines simply would not do. This works for me as I have learned to cram as much functionality as possible into limited resources. I can get working code written and debugged faster than most C coders can. I know nearly zero about Linux//Ubuntu/Fedora. Unless someone has worked on the simple old controllers one might not understand how exciting ( mouth watering even! ) it is to contemplate the peripherals this Sitara 3359 processor provides. I just need to get a jump start. Here is the problem, I want to write code for the Sitara-3359 and learn the nuts and bolts of low level programming (assy). I need some kind of a simple IDE Where I can take control of the processor from reset onwards ( barring un-by passable initializing code prewritten into the processor?). I have been searching all over the net for just that but come up frustrated by the huge number of names/acronyms and all. There are just too many branches to investigate. I get lost every time I try. For the moment I want merely to exercise the Sitara and study its responses, no desire to write any commercial application (with the possible exception of a camera interface for my telescopes). Please kindly somebody point me in the right directions. Once I have the correct IDE set up I can take over and dive into the details. No problem there.

You can only use gdbserver to debug user applications, not kernel mode code. If you want to use a USB100V2 FTDI based JTAG, you have to use Code Composer Studio from TI. Search Google for CCSV5. If you are using gdbserver, you simply start it on your BBB and specify the port that GDB will connect to. Then you can use any GDB based GUI to connect to the BBB using something like gdb remote ip address port. I haven¹t used this in a while, so you may want to check the exact form of the command. GDB is built into Eclipse, so you only have to setup a debug configuration and it will execute the same command. There are plenty of example on the net to show you how this is done. Remember to use the -g option when compiling to include the debug symbols.

I'll be around all day Saturday, and until about 11:00 on Sunday! Look me up if you're going to be there. I suspect the BeagleBone supporters will be greatly outnumbered by the AVR and Cortex-M folk, so we need to stand together! :) -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] sleep mode and wake modes..
Robert, I'm sorry to trouble you. Have you succesfully built an image with power management? I actually am looking for something that will go into low frequency mode or standby when I am not taking measurements (sleep for 5 minutes, wake for 1). Any solutions? Thank you for all of your hard work!

I am still quite new to BBB or BeagleBorad and arm in general. I looked all over the beagleboard.orgsite but only found documentataion for ubuntu, android and angstrom. I didn't see Debian. I know many or most consiter ubuntu and debian the same.. I do want to run headless no matter what and I found angstrom.. was not what I I was looking for. I did not want to learn a new operating system. I am familiar with Debian. soo thats why I was looking for a Debian image. is there a debian headless image on supported on beagleboard.org? if not a could make due with a stable headless ubuntu.. but it feels like an imposter (thats a joke) :) So the image i'm working on with beagleboard.org is posted here: https://groups.google.com/d/msg/beagleboard/D1ioNrzzXfQ/LdfJ2ccuiY4J This was last week's image. at some point I think I will want to compile my own kernel as well. but that is some way down the road. I have not compiled one sense i was in school. even headless there are lots of things I think I could live without for a proxy. so.. is there a headless debian image supported by beagleboard.org? For a simple headless/server image take a look a this: http://elinux.org/BeagleBoardDebian Couple different install types, depending on which board you have from beagleboard.org Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Go easy on me (first time poster). I am working on using the BBB in an embedded environment. It has the power I need to do image capture and machine vision processing as well as light control and data logging. The issue is that I only need to power it on once every 5 minutes (for a very brief time). I am looking into power management and see that some people have discussed kernel 3.12 as being better than 3.8, others discussing using android. Is there anybody who can definitively point me to how to control sleep or standby states in between readings (with wake up by RTC or interrupt)? The SoC can do it but has anybody succesfully compiled a distro that takes advantage of power management?

[beagleboard] For GSOC: Implementation of ZBOSS Open Source ZigBee stack on Beaglebone
I was looking for projects related to ZigBee on beagleboards. But the restrictions imposed by the ZigBee alliance has prevented the development of an open-source zigbee stack on linux. People are using the 6LowPaN stack instead which is open-sourced. I found an open-source ZigBee stack developed by DSR Corp. which has been approved by the ZigBee alliance. It supports a wide range of platforms and hence, I am thinking of implementing the stack onto BeagleBone Black for my GSOC project. Benefits: 1. Better mesh-networking capabilities. 2. AES-enabled security features on the zigbee network 3. Better compatibility with zigbee devices. I would love to work on this topic if a mentor is willing to take this up.

There is also a possibility that dtb is loaded correctly, but the kernel is too big and when decompresses overwrites dtb - it easy to check if the situation happened in your case with nm tool- no symbol should be loaded above c0f8 for default u-boot config, T. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
