I am new to the forum so hello everyone!
I have a problem with my own citroen c4 GP dash. The simptoms are constant resetting after only a second or two of working. With a huge amount od testing and debugging I have narrowed it to the cpu mx534. If I use freeze spray for a few sec the whole thing gets past that problematic constant rebbot stage an work normally for hours and days if I don't cut off the power. After that whole is the same - freeze spray to work or constant restarting.
I have a new cpu and I managed to trace out the jtag connecting points but since there is no mx534 on the list of supported devices I have sellected mx535 and the log is:
- JTAG chain detection found 3 devices:
- #0 Id: 0x1BA00477, IRLen: 04, CoreSight JTAG-DP
- #1 Id: 0x00000001, IRLen: ?, Unknown device
- #2 Id: 0x1190D01D, IRLen: ?, Unknown device
- ERROR: Cortex-A/R (connect): Could not determine address of core debug registers. Incorrect CoreSight ROM table in device?
- ERROR: Failed to connect.
Could not establish a connection to target.
- ERROR: Connect failed
Any help or suggestion is wellcome
