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"

 

or

 

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 ?

 

 or

 

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

Renee
