My customer is using a J-link to burn ADuCM350 mounted on PCB, some pieces of ADuCM350 can't be burnt after trying many times. I attached log file and burning script.
Can anybody help on this problem ?
Thanks a lot.
The logs show that the tool can see the debug logic of a Serial Wire device, but it can't access the rest of the chip. This indicates "something wrong" on the board, but no information on specifically what that might be unfortunately.
You would see this signature if the part was in power down mode...in this mode the J-LINK cannot communicate with the powered down logic. If these are brand new parts, then this is not expected. You would need code on the part to place it in power down mode, and typically would be seen on development parts on a bench.
Could the BOOT pin (N2) be stuck high on these board, this would place the part in kernel download mode where debug is prevented. If you have access to the UART, one way of proving this is using the CM3WSD and attempt to communicate with that. If it responds, then it is in kernel download mode and that would explain the problem.
