Hello everyone,
I have a hardware prototype with an ATMEL ATSAMV71Q21 that has ... gone through rough times (short circuit between core and IO voltage), meaning the device may have taken physical damage.
The board errors were fixed at this point, voltages, current draw and chip temperature are fine by now. I tried to connect to the Device using a JLINK and run into the following results:
SWD:
Display Spoiler
JTAG
Display Spoiler
The JLINK seems to find something (SW-DP with 2 IDs ... are those part of the ATSAM?).
Does this imply that the device is (not) damaged or does this not help on determining the ICs state?
Assuming the chip is OK, what would the results tell me?
Thank you very much,
Lars
