Hi there,
Yesterday I bought a beagleboard rev A5 and this is my first embedded linux experience. Also I do not know much about any kind of unix based operating systems.
Anyways, today while I was updating my beagleboard something went wrong I guess. Because when I connected to device after updating&upgrading process, angstrom was not booting anymore and I do not have any backup. Therefore I decided to reinstall angstrom by following the steps explained under subject “How to Unpack and BOot the Demo Image - easy way” at http://angstrom.s3.amazonaws.com/demo/beaglebone/index.html. However, now I have a few questions:
- While unpacking the image to the raw BeagleBone SD card, I used /dev/sdb as output target. However it is not something done with conscious. I do not know how to figure out which port my sd card is attached to. How can I understand which one I should use? (sda, sda1,sda2,sdb,sdb1… etc)
Lots of how-to articles on this on the web. Use ‘dmesg | tail’ to see what the last drive added is. This requires you to insert your card just before issuing the command.
- It has been 3.5 hours since I started unpacking process. Does it take this long or is it because I choose wrong output target address? Also I see lots of meaningless characters on the screen. Is it normal? (Check out the attachment)
That isn’t normal. What exact command did you issue?
- I did not format SD card. Because it was not listed under “How to Unpack and BOot the Demo Image - easy way” guide. Is not it necessary? Aren’t I only unzipping angstrom image to SD card? If so, why do not I delete nonworking angstrom image?
You don’t need to delete or format from Linux.
