[SOLVED] OP boot problem

[CVL]

Nothing special on normal raspbian boot.
GPIO 22 and 27 are  free of use.

Maybe you need enable the serial interface? is disabled by default on OP 0.10.0. Go to menu - Raspberry Pi configuration - interfaces
have you installed the software your hat needs?

thanks for the hint on the serial interface - I had already tried that - but the real culprit was the serial console in /boot/cmdline.txt
After removing it, OP starts normally.

Sadly, I am coming back on this issue, as I don't get OP to start anymore with the Pico hat since I updated to 0.11. It always boots into safe mode. I tried all combinations on the serial line to no avail.

To be sure, I installed a clean Rasbian lite on another SD-Card, and there it is working all right. So there must be some difference between clean Rasbian and OP. Any ideas to where to look?
Modules are the same, except bluetooth modules loaded by OP, could it be useful to blacklist them?

I am stuck, as there are no entrys in the log-files, and dmesg on the emergency prompt just shows the messages of the safe mode.

 Going back to the original 0.10 image won't give better results, no clue why.

Any help is much appreciated
