beagleboard recovery take 2

-
[2013-03-06 update]: after a few years of letting things rot, I just managed to pick up my old binaries and gave it a dry run: https://github.com/nmenon/beagle-recover  has the original working binaries since the google groups link no longer work. NOTE: I HAVE NOT TRIED WITH ANY OF THE LATEST SOURCES. I do not have plans to do so in the future as well  - an quick try indicated things are broke :( [Original post] http://groups.google.com/group/beagleboard/web/beagle_recover.tar.bz2 has the recovery package ready to go for ubuntu 8.04 32bit OS: download this, run sudo ./recover_beagle.sh - as shown in the video... Steps summary: 1. first shutdown the board. 2. run 'sudo recover_beagle.sh /dev/ttyUSB0' in a terminal -> you need super user permissions(sudo permissions) to run this script. 3.

What exactly is Configuration Header(CH)? CH is a set of register values to the critical OMAP registers that define how the clocks, sdram controller, gpmc controller, mmc controllers are configured.. it is more like an array of register values - you fill them up with the correct values, and store the load address you would like the resultant image to load up, bingo, we have the image booting off that location.. There are few of these structures that are defined in the TRM which has a detailed description on the real...
