I have just got a new PC Engines APU6B4 Board as I wanted to test one with an SFP slot. In general it booted fine and the ethernet ports are numbered eth0 to eth3, whereas eth0 is the SFP port (so the same order/logic as with the APU2 boards).
The LED driver does not work:
dmesg |grep -i engine
[ 0.000000] DMI: PC Engines apu6/apu6, BIOS v4.17.0.3 08/22/2022
[ 12.713451] pcengines_apuv2: failed to detect APU board via DMI
[ 13.020084] pcengines_apuv2: failed to detect APU board via DMI
[ 13.191974] kmodloader: - pcengines-apuv2 - 0
Maybe it is just a small patch needed to adapt for the board model reading "apu6"? Has anybody else already made some experience with the APU6 boards?

Small regres… sion. The led-apu2 driver which did support the APU4 was removed in favor of the pcengines-apu2 module. However, the pcengines-apu2 in the 5.4 branch does not support the APU4 [1]. The module in the 5.5 branch does support the APU4 [2].

Since kernel version 4.15 there is a new driver stack for APUv2 and APUv3 boards… available.
We now use kernel version 5.4 on x86_64 targets. So we could use this new driver stack for APUv2 and APUv3 boards.
