I have followed instructions https://wiki.ubuntu.com/ARM/ to write the image for Ubuntu 12.04. I had already done this before once in the past but with 11.10 Ubuntu sever Ed. Now I would like to write the 12.04 version because is supposed to run fine with OpenFrameworks. I have some problems with my SD-card reader also (maybe is not a very good one??) and can't follow the instructions listed, id est:

zcat ./ubuntu-12.04-preinstalled-desktop-armhf+omap4.img.gz |sudo dd bs=4M of=/dev/sdb ; sudo sync

But instead I have to use this:

sudo sh -c 'zcat ubuntu-12.04-preinstalled-desktop-armhf+omap4.img.gzz > /dev/sdb' sync

That is more comfortable because I have an output on the screen. But the problem is when I plug the SD-card into my Pandaboard and start Minicom. this is my output:

After those lines nothing happens .... normally should begin the customization process, but never happens. Anyone can give my advice? Honestly I did this not so many times, so maybe I forgot something or made something wrong. Maybe my SD-card reader does not work properly?

Thanks in advance

  • Did you get it working? I would like to know a few more details of the same so that I can get a better idea. Share the environment variable values in boot using 'printenv'. Share the data in preEnv.txt. Above all, I would like to know the output in the Display of Pandaboard. – Anoop K P Jan 17 '13 at 6:46

Relative to the pre-installed images, it is sometimes more worthwhile to go through the instructions at ELinux.org to create a netinstall image instead to set up Edubuntu or whatever flavor you would like. That's the work-around I had to follow with my BeagleBoard as the pre-installed 12.04 image booted great but then accepted no keyboard or mouse input from me.

  1. Check if you have led blinking continuosly.
  2. If yes: Then you should just connect your Keyboard and HDMI display to the board.

Worked for me. For more details checkout : Official help on the issue

  • @Whaaaaaat " Then you should just connect your Keyboard and HDMI display to the board." -->Is the essential part of the solution. The user is just checking is serialport and not the HDMI display. Official help is mentioned for extra references. – Pranaysharma Oct 3 '15 at 9:08
  • Please try to include some of those extra solutions as well. Sometimes, your solution will work, but it won't for others (especially if the link goes down). It's best to have all possible troubleshooting methods displayed here in brief. – Kaz Wolfe Oct 3 '15 at 17:59
