Hello,

I have a custom board with 32 MHz crystal. My program(Just to ON the 2 LEDs) is flashed with no error and I am sure of that referring to this answer by tesc, hex file is FFFFFF.....

But program is not working(LEDs are not glowing). LEDs are ok and pin defined in program is also right. So, It may be the error of clock/crystal.

I am not getting this whole #define NRF_CLOCK_LFCLKSRC thing and its structure. Can you explain it?

So, what should I write in #define?

Have you applied the changes I suggested in my first comment?

Are you able to debug the application?

Make sure that you have removed the DEVELOP_IN_NRF52832 define from the Preprocessor Symbols as this will enable nRF52832 workarounds that are not compatible with the nRF52810.

Also, the rc_ctiv value should be 16 and not 32, i.e.

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC,
.rc_ctiv = 16,
.rc_temp_ctiv = 2,
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

What about to write your own simple FW which has UART debug logging and you place proper debug after each step of initializing things in you code? That would be standard procedure for me (in opposite to guessing from schematics why the FW don't work;)
