Thank you for reply. I measured my official psu and it gives me 5.32v on output. I think it's enough for OPI. Also when I boot system from official OPI page its works well but without drivers (script.bin file). With script.bin it hanging on following log message: [ 4.270097] [DISP] disp_device_attached_and_enable,line:159:attched ok, mgr0<-->device0, type=4, mode=31.
Of course I tested it with others psu:
- official orginal samsung 5.3---2.0A
- Xiaomi powerbank 5.1V---2A
Still not works.
