No errors found


Going to try 624

PS - no problems with 624. It runs for somewhere between 30 and 60 second during boot (extended period with white LED) which I guess is too short. Then again I am not sure if there is something intermittent on my phone! (Standard evasive guess when trying to debug and get something repeatable!!!). Just trying memtester on 1G at 624. then tomorrow will try memtest=256 or something.
