returning with update on my case:
-
did finally see ui with setup wizard, finished it and press “reboot”, device goes to reboot and stuck in black screen.
-
I’ve attached external hdmi device and saw that it is “sd card not detected” issue. Poking around checking different sd cards and video about rpi 5 issues, I’ve found something similar but for full RPI 5, guy there made video and replug card few times during boot-source-loop and finally start OS.
-
In my case to bypass “sd card not detected” issue I need to boot device without card, wait some reasonable time assuming it fails on initial read then put sd card back and it magically start reading kernel loader and passing control further. BUT.
-
If I keep hdmi connected then I see bg picture in blue tones with boat on external screen, main still black, no keyboard or tracker working either. With detached HDMI screen black and after reasonable time of wiaing attaching HDMI also gives nothing.
I need to mention that I have 3 usb-c board expansion (uHub Expansion Card) installed, but removing it nothing really change (or I missing something).
Any thoughts or ways I can provide more debug info?
