Hi,
I just assembled the v4 kit, and I must have overlooked something (or broke something), because I’ve never seen the screen come up (yet…).
Despite the advice to use RC-2 of the image I picked a fairly recent one (and to make matters worse, I succesfully updated it in webconf and ran a dist-upgrade, so I should be in a known “current” state.

Most worryingly it seems that
./zynthian.sh: line 55: /sys/class/backlight/*/bl_power: No such file or directory
if I login into the system as root, indeed, that does not exist:
root@zynthian:/sys/class# ls backlight
ls: cannot access ‘backlight’: No such file or directory
I always connected the screen with the red ribbon to pin 1, so I hope that the screen itself isn’t the issue…
Any tips to recover and proceed ? (Oh, if really need be I can install rc2 but os.zynthian.org seems to be down.)
