Hi!
I was able to setup nfsroot, and boot postmarketos (with root
read/only, but that's good enough for debugging).
Then I was (finally!) able to run dmesg, and that tells me:
[0.816040] mousedev: PS/2 mouse device common for all mice

In panel-dsi-cm.c it's set to maximum with
dsicm_dcs_write_1(ddata, DCS_BRIGHTNESS, 0xff);
Sebastian suggested the same but used 100 instead of 0xff, which might
be a bit too low. You can also add msleep(1000) after
dsicm_d
Hi!
So I got it to work; here are my notes from debugging. I put them on
https://elinux.org/N950 , too.
If someone knows how to fix the backlight, it would still be useful.
Best regards,
Pavel

I did take a quick look at the board-rm680.c since there are some
conditional statements with regards to system revision but I didn't
notice anything that might prevent it from booting.

Yeah, some early N950s may have only 512 MB.

Hi!
...hardware should be identical. 3.5.3-nemo kernel seems to work on
both. 4.13-rc2 with display and clock patches boots on phone "S", but
does not on phone "P"; nothing nothing is received on serial port.
There is some difference in the bootloaders: S's bootloader provides
lots of debug info,
24 matches
