Hi, I have been given a product (Presonus 16.0.2) to repair that the chap had fiddled with and managed to short the erase header on the front circuit board. as the manufacturer is slow to be forthcoming with any file to replied to the erased SAM7 chip in question, do you think it would be possible using the ICE and built in Jtag header to copy the contents of a working unit and load it onto the erased chip?

 

This is not my area of knowledge, but I have access to a SAM-ICE. It seems mad to be replacing an entire section when it is simply some erased programming that is the issue.

 

Any help or advise would be much appreciated.

Cheers, Chris
