Can you tell me how I'm able to enable PWM? I'm not able to see any of them in the armbian-config overlay management

I use BalenaEcher.. never tried Raspberry Pi imager.

moved to beginner. User seems unsure which board they actually use (r6s vs 5rc).

Hi, I tried your Debian/minimal/IOT for NanoPi 5RC, it's great, I would like to use it. However the RTL8822CE driver only exposes wlan0 and there are no parameters to set, and I need two wlans. For reference there are two wlans available in the core debian image from FriendlyARM/ELEC. Best regards.

I'd recommend looking at the script /root/install-aml.sh. This is the script that would copy from SD to emmc (if that was supported with your CPU). It is a pretty simple script and you can see the logic it uses to copy the root partition to another medium.
