Call me crazy, but I would expect they'll need more information than you

provided us here. /o

You might find it less challenging if you use something more advanced than twiddling

LEDs ... a debugger, perhaps. Regardless, I'll go out on a limb here (since there's not

much to go on) and guess your EraseFlashSector code is broken -- and you're

looping forever at:

while(*CommandSeq6 != 0xffffffff){}

Anyway, good luck!
