I want to make the NFC pin the default I/O pin

Hi,

Apologies for the delay. The command is correct, but the address 0x00FF8028 coressponds to the UICR-NFCPINS register for the 5340 SoC. You should use the 0x1000120C for the 52832SoC as mentioned here: https://docs.nordicsemi.com/bundle/ps_nrf52832/page/uicr.html

Regards,

Priyanka

Is the rewrite command below correct?

nrfjprog --memwr 0x00FF8028 --val 0xFFFFFFFE

Hi,

Yes, you can set the NFC pins as GPIO as default by changing the NFCPINS state in the UICR.

Please remember to perform an nrfjprog --eraseall after changing the UICR NFCPINS value so that your change is reflected.

Hope this helps.
