Have you made any progress since you sent this email? As far as I know, this early in the code there is no difference. If you have more information on your debug step, I may be able to find something. What tool do you use? cheers, REnaud On 22/04/2014 13:34, Tobias Waldekranz wrote: > Hi, I'm currently trying to bring up a P1020 based board which boots > from a NOR flash.
