NRF54L15 Zephyr Blinky Sample did not start at Power on

Hi

The Blinky Programm only starts when I give the reset Go command via jlink commander.

At Power cycle nothing happens.

If i give the SOC an external Pin reset the running programm stops but never starts

just drag and drop it into where you are typing. Alternatively: Insert -> image/video/file -> then click the upload button:

It is not clear to me whether they have put a 32kHz Crystal (LFXTAL) in that module. I can't seem to find any datasheets. If you are not sure, reach out to the distributer that you used to purchase the module, and ask if you can get the datasheet. 

Does the way that you supply power change when you are running the debug session and when you are trying it without the debugger attached?

Best regards,

Edvin
