Hi,
I was successfully running Armbian on my Pine A64+ board, using the 7" touch screen from 2016, first using the Longsleep kernel, with mainline kernels from 2021.
See https://forum.pine64.org/showthread.php?tid=3482 thread for more details.
Regular Armbian upgrades were fine until around the beginning of this year - Armbian kernel 6.1.104 (02/02/2025).
But a kernel version somewhere beween that and the next currently available Armbian kernel 6.6.750 (03/02/25) has broken the output to the touchscreen.
I haven't been able top source intermediate kernels and device trees, so can't say exactly where the change happened that broke the output.
Rolling back to 6.1.104 fixes the display with no other changes.
I don't see any changes in logging boutput related to mipi-dsi or display and don't have access to a serial connection to view the early boot process, so am stuck.
Does anyone else still use this board with the 7" touchsceen and have they been able to run it with a kernel later than 6.1.x?
I'd be very interested to know what changed and how to fix it without freezing the kernel.
