[arm-allstar] Won't boot from SD

[Doug Crompton]

Robert,

  It sounds like you have already made the checks but if the emmc is damaged in any way the SD card will not boot. This is specific to the 1.2.1 version and we are aware of it and we are working on the problem. This would NOT normally be a problem and the only time we have seen it was when someone purposefully erased a file on the emmc and then could not boot the SD. I am attaching a PDF file on how to recover from that problem.

>From what I read in your situation that does not seem to be the problem you are having  but I would like you to try the procedure outlined in the PDF.  It is a much easier way to write the emmc and takes very little time. If this does not work for you then try to burn another image of something completely different like the Angstrom image and see if that boots just to make sure the SD slot is working.
