Update; After a hard reset the code runs as expected. Success!

Thank you for your help

I have changed my prj.conf.

CONFIG_GPIO=y

CONFIG_BOARD_ENABLE_DCDC=n

CONFIG_RESET_ON_FATAL_ERROR=y
CONFIG_GPIO_AS_PINRESET=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y



CONFIG_BT=n
CONFIG_DEBUG=n
CONFIG_LOG=n
CONFIG_CONSOLE=n
CONFIG_USE_SEGGER_RTT=n
CONFIG_PM=n

and added the following the Kconfig.board

config BOARD_ENABLE_DCDC
	bool "Enable DCDC mode"
	select SOC_DCDC_NRF52X
	default y
	depends on BOARD_DCLOCK32

This was unsuccessful. Any other ideas?

It seems like you might be encountering a similar issue to what was discussed in the Nordic DevZone forum. In that case, the user was able to build and flash the program successfully, but it only ran when the debugger was started. The program did not run when the chip was standalone, which seems similar to your issue.

Check if you have enabled DCDC in your code. Specifically, check if BOARD_ENABLE_DCDC is enabled in your config.
