Hello,
We are using Ubuntu Server 20.04.6 with Kernel 5.4.0-144-generic, and BIOS version is: UP-ADLN01 R1.2

I also updated the BIOS to 1.7, reinstalled ubuntu 20.04 (5.4.0-144-generic) and pinctrl driver, and still can't access the pins

Hi @CyB0rG
Sorry for late reply.
The kernel you are using (5.4.0-144-generic) does not contain the driver required by pinctrl.
Please install the iotg kernel with apt server and try again.
5.15.0-1055-intel-iotgBest Regards,
Harry Chiu
