Nice!nano custom board problem (nRF52840)

[DaniGia21]

Hi everyone,
I'm here to ask if anyone could help me solve the problem I'm having when programming on the nice!nano board.
In my project, I created a new board called nice!nano. After that I assigned the pin p1.06 as a led, putting the code in the main to make it blink. I can compile correctly, the problem is when I program it on the uC it doesn't work. The led doesn't blink.
If I try to use the standard board of the nrf52840 dongle it works.
I would like to solve the problem of the custom board also explaining where I'm going wrong because I'm a neophyte with this uC.

I'll leave my code here.

Thank you very much.

I suggest to use simple sample like "hello world" from NCS SDK to check your custom board is OK first.

I have already tested my board and it works fine. I think the problem is with the custom board settings, because I tried with the nrf52840 dongle settings and it works.
