how to remap pin(pin 0 & pin 1) port 0 to gpio

[VADIM KADUKOV]

On the nRF5340  P0.00 and P0.01 are used for the 32.768 kHz crystal by default and are not available as GPIO on the connectors.

how to remap  this pins to gpio?

Hi,

 The 32.768 kHz crystal can be disconnected and the pins can be used as normal GPIO by cutting the solder bridge on SB1 and SB2, and soldering SB3 and SB4.

Hi, 

thanks, but this not help. When i trying to write "1" to P0.00 or P0.01, i have "0" at pins

to use P1.02 as gpio help CONFIG_NFCT_PINS_AS_GPIOS=y in prj.conf

Hi,

I am sorry but I cannot understand your query.

1. Did you try following the instructions in the link that I had provided earlier? Even after that it's not successful?

2. Do you wish to use P1.02 also?

Regards,

Priyanka

Best regards

Hi,

Are you using a custom board or the nRF5340DK?

Also, pins P0.00 and P0.01 are used for 32kHz crystal and the P1.00 and P1.01 are digital I/O pins which can be used as GPIO pins.

As for P1.02, what do you wish to use it for?
