Hi,

P1.00 is at Port 1, Pin 0. Which mean that you should use #define led NRF_GPIO_PIN_MAP(1,0)

I measured 30 - 40mV no matter I set or clear this GPIO.

#define led NRF_GPIO_PIN_MAP(1,9)


//nrf_gpio_pin_set(led);
nrf_gpio_pin_clear(led);

But what voltage level do you see if you measure directly on the pin?

It is a custom board from Taiyo and the schematic looks like this. I connected a LED + resistor to this pin and it doesn't light up as the I connect them to P0.xx GPIOs.

Hi,

Are you using a custom board or a DK?

What do you measure on the pin when you try to toggle the signal?

By not working, I mean when I connect LED to pin 25, LED will work. However, same code won't work on pin 1.00 or anything like P1.xx.

Hi,

Can you specify what you mean by doesn't work, the pin isn't set to VDD? Have you measured directly on the pin? Are you using a DK or a custom board? If you're using a custom board, could you share the board file that you're using.
