nRF54L15 custom board file --- Will not build

[sleeper]

I get this error after creating a custom board

C:/ncs/v3.1.0/nrf/subsys/mpsl/init/mpsl_init.c: In function 'm_config_clock_source_get':
C:/ncs/v3.1.0/nrf/subsys/mpsl/init/mpsl_init.c:335:10: error: #error "Clock source is not supported or not defined"

If i use nrf54l15dk/nrf54l15/cpuapp board target all works.......

So it looks like the Create new board function is not working correctly ?

Hello,

The board generator will create the required board files and populate most of their content to give a starting point for assigning the pinout, selecting clock sources, etc (Creating board files). The clock node in the devicetree must be enabled explicitly as done here: https://github.com/nrfconnect/sdk-zephyr/blob/7d3bd3993600d433ab0653391aee2fa2b4ce3fda/boards/nordic/nrf54l15dk/nrf54l_05_10_15_cpuapp_common.dtsi#L100. If your board includes a 32K crystal, then you may also need to configure the load capacitance here: https://github.com/nrfconnect/sdk-zephyr/blob/7d3bd3993600d433ab0653391aee2fa2b4ce3fda/boards/nordic/nrf54l15dk/nrf54l_05_10_15_cpuapp_common.dtsi#L36 

Best regards,

So ive just started creating using devicetree visual editor...... Spent the best part of 90mins on this and then its just disapeared.....

How can you have tools in this day and age that perform like this.....

Your above comment is not great testament to devicetree visual editor, does this actually work ? because so far its wasted 90mins of my time.

Was it just the UI window that disappeared, or did your work in the DTS file disappear as well? There should be a warning like this if you attempt to close editor without saving:

The files are still there its like all they dont linkup together anymore.

What i really need is a detail tutorial on how to create a new board from the beginning, this way i will learn how to do this correctly :-)

I'm not sure if you saw it, but I linked to the Creating board files section of the nRF Connect SDK Intermediate course earlier. The screenshot you posted shows that your DTS file contains many errors. Please switch to the text editor view to see the errors underlined in red.
