I agree, the only solution with the TrustZone enabled that worked for me is by adding this line.

I have had this issue as well and the above solution does not work for Trust Zone projects.

looking in nrf54l_05_10_15.dtsi

#ifdef USE_NON_SECURE_ADDRESS_MAP

/* intentionally empty because UICR is hardware fixed to Secure */

#else

uicr: uicr@ffd000 {

compatible = "nordic,nrf-uicr";

reg = <0xffd000 0x1000>;

};

#endif

So for the non-secure builds:

&uicr {

nfct-pins-as-gpios;

};

CONFIG_NFCT_PINS_AS_GPIOS=y

Does not work.

In the case of non-secure and also secure, adding the following line will fix the issue in both cases:

NRF_NFCT->PADCONFIG = 0;

Hi,

You can add the following configuration in the overlay.

&uicr {

nfct-pins-as-gpios;

};

hello，I have tried to disable NFC in the devicetree.

&nfct {

status = "disabled";

};
but,the PADCONFIG register is still 1。Do you have any other methods to set the PADCONFIG register is 0?

I just faced the same issue, and I was trying to disable NFC in the devicetree.

&nfct {

status = "disabled";

};

Is this "work in progress" ? - I think accessing the HW regs directly is an ugly solution ;-)

Hi Priyanka,

Thank you for your reply! I solved this problem that assign values to the register " NRF_NFCT->PADCONFIG = 0" .

Hi,

For nRF54L15, you need to Disable the NFC use using the PADCONFIG register.

PADCONFIG.ENABLE=Disabled

You ca find more details regarding the same, in the Product Specification of the nRF54L15.
