Hi there,
A bit of context: I discovered Zynthian around a month ago and build a custom kit with what was taking dust on my shelves (RPi 3B+, official RPi touchscreen, Behringer UCA202, Belkin USB2 powered hub and an empty box of macarons).
Everything is powered by a 5V 6A adapter bought for this build, RPi directly from the output and the rest from the powered hub (itself being powered from the output the adapter as RPi).
It was working pretty well with the previous stable release (2401, pre-Oram).
As Oram has gained a stable release and seems to be a great update, especially for touch only builds, I tried to burn the new image (Oram stable 2409) to my SDCard.
Problem is the display is not working at all; black screen but also no backlight, as if it was not powered.
I can access to webconf (from LAN), but configuring the whole thing do nothing, same problem at reboot. I tried to power the display in different ways, but still no luck.
So I flashed the old image (2401) just to see what happens, and everything works fine with the previous release, so it’s not a powering issue.
I’m not sure if someone has already had this kind of problem. As it’s a custom build, I ask here rather than filling an issue on Github, but please tell me if I need to.
BTW, this project is really nice: it lets me reuse things that were standing there for nothing, replaces a lot of gear that I had to remove due to moving in a smaller place, makes me rediscover (very) old plugins like mda ones… coolness++
