>the PBP booted showing the u-boot screen
Maybe you mean the login screen? Most (nearly all) uboots only display over serial
>I also read that it is possible to boot the PBP without eMMC. That does not work with my PBP.
I think you need a "hard reset", the button inside OR hold pwr button for 20+ seconds
(since pbp has a battery, if it gets into a 'bad state' it can remember that state)
Maybe the uboot on emmc (which has priority) is defective OR maybe some video mismatch
The blinking leds suggest a uboot problem
I suggest leaving emmc out until you get a reliable boot, then you always have a 'fall back"
------
wifi firmware,, since it seemed to work OK, I am still on the 1st firmware version, that is, I pinned it
(late 2019) For some reason, when the update in 2020 came out, it only helped some people, not all
Not clear what is right or wrong
