Armbian_23.02.0-trunk.0179_Rock-5b_jammy_legacy_5.10.110_minimal.img.xz From here https://github.com/armbian/build/releases/download/ Do I need to go to trunk.0186?

Nope, still doesn't work. Then it also means that the option provided to flash the SPI flash doesn't work! It takes a few minutes and doesn't indicate any errors, but seems to leave me with the old Radxa boot loader.

I'd like to get Armbian to boot from NVME on the rock-5b, but have not had any luck with that, though I've not tried recently. Also, I've had zero issues with my PD supply that so many have highlighted. At this point, after re-reading this long thread, I'd like to ask if I've understood it correctly. If I : - boot the latest Armbian image from SD then use it program SPI flash as provided for in the install procedure. - then dd the Arbian image to the NVME device, - then shut down, remove the SD card, and power cycle, It should work, right? It did not the last time I tried it. If however, I dd the Radxa image to NVME it boots correctly everytime.

Oh! Thanks, but I've given up on Armbian for the Rock-5b. The Radxa image suits me fine and boots from NMVE.

With Linux rock-5b 5.10.72-rockchip-rk3588 #trunk.0102 SMP Sat Nov 5 07:56:18 UTC 2022 aarch64 GNU/Linux I see only one PWM controller pi@rock-5b:~$ ls /sys/class/pwm/pwmchip1/ device export npwm power subsystem uevent unexport pi@rock-5b:~$ cat /sys/class/pwm/pwmchip1/npwm 1 How do I figure out its header pin assignment? Is there a device tree overlay to expose all 4 PWM controllers?
