Thank you for your immediate response and help!
May be, I used the wrong "name" for the boot info screen. Here is a photo of the screen before it goes black with the blinking cursor and then flashing orange-green power LED.
I pressed the internal reset button many times and also pressed the power button for 20+ seconds. That did not change the PBP behavior.
I share your assumption that the uboot on the eMMC is the problem. Unfortunately, after removing the eMMC the PBP does not even boot. THe power LED stays off during boot without eMMC. In one thread I read that the LED is switched on via software (not hard-wired) during uboot. From this, I assume that the SD card's uboot is not executed when the eMMC is removed. Does removing the eMMC require to switch off the eMMC card using the switch no. 24? If yes, then please help me withe the new board layout. It changed compared to the PBP version in 2020. With the new PBP, the switch is not available as described in the wiki tutorials.
Regarding the wifi: running the 2022 PBP with the old eMMC, does not detect/recognize the wifi card. There are no settings for wifi available. Thus, it seems that the old Manjaro KDE Plasma OS does not detect wifi at all in the new PBP. I will try to update the old eMMC to the latest Manjaro KDE Plasma using the old PBP. Unfortunately, my old PBP freezes after 10-15 minutes of using it. I could never fix this issue with the 2020 PBP. My hope was to have a new working PBP and then replacing parts step-by-step to identify the problem with my old PBP. If the PBP does not freeze too early, the old eMMC will be updated and I can use the newest distro to run in the new PBP. May this solves the wifi issue.
Still, I like your suggestion to first get the new PBP running without eMMC. Do you know any steps to follow? Right now, the PBP does not event switch on the power LED when I remove the eMMC.
