Hi , Sorry for the late reply, was having a break for chinese new year

I think i did not make myself clear , I comment out this

&gpiote0 { status = "okay"; };

and did not change the rest

and the board now works

1. yes,i have been using 2.5.2 for a long time

Hello,

Do you have some old project that you are working with since you are using NCS 2.5.2?

Did you make any changes to the project to reflect your custom board?

Is the build working now or do you see other issues with the parts you've commented out?

Best regards

Asbjørn

i have this error

Hello,

I'd recommend you to have a look at the documentation here:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/config_and_build/hardware/use_gpio_pin_directly.html

You should aslo be able to check the GPIO names with the correct absolute pin number, you can use the NRF_GPIO_PIN_MAP helper macro in nrf_gpio.h.

Best regards

Hi Asbjørn, thank you for the reply!
Can you show me any sample on how to "do the same configuration writes directly to gpio0.8 to make sure you set the right pin"

I attached my schematic as reference

Also parts of my overlay file, can this issue due to disable some features? but I did the same thing with development board

I use the same overlay file to test on my customized PCB and development board

&i2c0 {	status = "disabled";};
&spi0 {	status = "disabled";};
&i2c1 {	status = "disabled";};
&qspi {	status = "disabled";};
&led1 {	status = "disabled";};
&led3 {	status = "disabled";};

Hello Zhang,

Not sure how you are configuring the settings for your custom board, but I suspect that gpio0_dev isn't working on the same gpio on your custom board as it is on the development board.

So check which gpio is used by the gpio0_dev is using or do the same configuration writes directly to gpio0.8 to make sure you set the right pin.

Best regards

Asbjørn
