This fixed my problem as well.

I was struggling for a for a day and a half to debug/run code on a custom board with an nRF52833 on it.

Hi,

I'm glad to hear that this helped you solve your issue!

[quote user="rhinodavid"]I did notice that in order to get the build to work after setting `CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y` I needed to set `CONFIG_UART_CONSOLE` to `n`. Does this mean one must have an external LF oscillator in order to use UART?[/quote]

The UART peripheral does not have a dependency on the LFCLK source, it only uses the HFCLK. Not sure what can have caused this issue on your end. If you still experience issues, I'd recommend that you open up a specific thread on this issue.

Kind regards,

Håkon

I've been banging my head against the wall for 3 weeks trying to get a custom NRF52810 board to work and this finally solved it. Thank you so much!

Hello Håkon,

I think that solved the problem.

Thank you.

Hi,

You are stuck trying to start up the external LF clk, and I assume that your custom board does not have an external 32k source mounted.

Can you try to add "CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y" to your prj.conf and see if this helps?

Kind regards,

Håkon
