Ok, this morning apt-get upgrade tells me that there is armbian-config to update. Done and now solved the overlay issue also on my old image Thanks

Unfortunately all these solutions did not work. But by installing the latest Armbian Noble Gnome installation, and changing the overlay_prefix=rockchip line in the armbianEnv.txt file I can select the overlays. Evidently my image was corrupted, or the upgrade failed. Now, I have a bigger problem is to enable the fan on Rock-3A, and it does not work even loading the PWM8 overlay of radxa. Then I did a bit of research and since the Armbian dts change a bit, and I spent hours rebuilding this driver, but it does not work. I do not know if anyone has enabled the fan on the dedicated connector of the Rock-3A. Here is my dts: /dts-v1/; /plugin/; / { metadata { title = "Enable PWM8-M0"; compatible = "radxa,rock-3a", "radxa,rock-3b"; category = "misc"; exclusive = "GPIO3_B1"; description = "Enable PWM8-M0. On Radxa ROCK 3A <= this is pin 16. On Radxa ROCK 3A >= this is pin 16. On Radxa ROCK 3B this is pin 16."; }; }; &pwm8 { status = "okay"; pinctrl-names = "active"; pinctrl-0 = <&pwm8m0_pins>; }; This doesn't work, maybe because I read somewhere that Linux 6.xx has problems with PWM ? For now I'm happy with setting GPIO3_B1 pin to 1, and the fan works, but if I run this: #Fan controller echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip0/export echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip0/pwm0/period echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip0/pwm0/duty_cycle echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip0/pwm0/polarity echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip0/pwm0/enable The fan doesn't work, the pin is that one and radxa recommends PWM8. For now I have to give up on the silent fan, then if there are updates I'll try. Thank you very much for your help

Hi all, I'm new here, but I know armbian since years ago. I have a Rock3A and I downloaded the latest Armbian 25.2.3 bookworm, at the first try armbian-config worked. But after an update I had a problem with armbian-config, I reinstalled this tools that was corrupted. Here are the problems with Invalid overlay_prefix, and after searching everywhere and doing some tests I found the solution, here it is: mkdir /boot/dtb/overlay cp -r /boot/dtb/rockchip/overlay/. /boot/dtb/overlay/. cat /boot/armbianEnv.txt verbosity=1 bootlogo=false console=serial extraargs=cma=256M overlay_prefix=rockchip overlays=rk3568-pwm8-m0-fan fdtfile=rockchip/rk3568-rock-3a.dtb rootdev=UUID=194f1dc9-d186-438e-b1fd-064e3e8b1304 rootfstype=ext4 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u my files start with overlay_prefix=rockchip, then armbian-config and now your overlays selection works. The folder basically needs to be moved, hopefully that will be done in the next image. I hope it can be helpful for those who have the same problem. In my case I have not yet solved the fan operation on pwm8, which works with S.O. Radxa. I also tried to compile the dts downloaded from Armbian, but there must be some problem on the kernel that has not been solved. If anyone has managed to get the fan to work on the Rock3A connector, I would be grateful for any help1 Thanks Tony

Hi, so far i used armbian on Orangepi board, now i switched to Rockpi. Is there a way to pass my work with a backup from one board to another? I already have the Orangepi backup, I thought about replacing only the boot part, is that it? Can anyone tell me if there is a procedure? A thousand thanks
