Hello,

I rollback the modifications made on my own to DTS to keep raspberry pi's original version.

I want to test device tree overlay proposed by the supplier.

I just add the line dtoverlay=pineboards-hat-ai on /boot/firmware/config.txt,

If you have a kernel greater then 6.6.30 I recommend to use this method instead of modifying the DTS yourself.

Thanks @mikegapinski for the link to the tutorial.

Generally, the address changes each time RPI updates the device tree, so you’d need to update it on every update. The overlay is the only way around it.
