Using a M22330Demo board I see the following errors occur when I connect the USB cable and then try to debug. 


I get one of the following messages:


1) "ColdFire PE Protocol Adapter :An error occurred while trying to write memory"




2) "Downloading 4284 bytes" and then another window appears and says

 "Memory Write Verify Failure


Memroy write to address 0x322aef6 failed to verify: 

Expected value: 0x20000900

Actual Value : 0x0

Retry ?




3) Coldfire PE protocol adapter: No USB connection found


If I keep trying it will eventually make it into debug mode.  But most of the time I get an error.


I have tried this on 3 computers and not had any success. But if I load codewarrior on one of 2 older computers I have and then try it seems to work OK.   Could it be that the 3 computers are running the USB at a higher speed and the higher speed isn't reliable?   These 3 computers are newer computers than the 2 that it works on.




Has anyone else seen this and is there a solution?


Thank you
