piSerial "WARNING: Wrong CRC received"

[Philemon Benner]

Hey,
today i was setting up a revpi compact with the newest system image from the kunbus downloads page: 2024-02-15-revpi-bullseye-arm64.zip. When i tried configuring the pi the factory password was empty after the setup. When trying to get the password with piserial i get the following output:

Code: Select all

pi@RevPi*****:~ $ piSerial -p
WARNING: Wrong CRC received
ERROR: FATAL: Can't get serial number from device

I already flashed another pi with the same system image and there it worked. I also tried using revpi-factory-reset but same issue there.

Hi

Has the correct overlay been loaded (dtoverlay=revpi-compact in /boot/config.txt)? Are there any errors in dmesg respective /var/log/kern.log?

Hey,

yes dtoverlay is revpi-compact in /boot/config.txt.
There are only two messages in dmesg that are marked red which are:

Code: Select all

[    3.241724] rtc-pcf2127-i2c 1-0051: hctosys: unable to read the hardware clock
[    6.472029] piControl: config.rsc is empty! Probably needs to be configured in piCtory

Could you please attach the complete log file?
