7 months ago @tloanPhytec new eeprom-flashtool version is on kirkstone-next and should be public within the next days. I fixes all your findings.
However, to write the correct PCB rev, please add -rev 2 as argument.
Seeing the following when testing on my PCM-071-5432DE11I.A0 dev kit:

I believe some bugs are present:
PCM-071-5432DE11I.A0 has (according to BOM lookup):
The output of the 'read' operation is reporting:
Please advise if I'm doing something incorrectly if you notice anything 🙂
