This device is not using DCDC converter, and I assume that this is the problem. I could not find the correct config value to use the LDO.

Who to configure?

I tried:

CONFIG_DCDC_NRF52X=n

CONFIG_BOARD_ENABLE_DCDC_APP=n

both are undefined.

I guess this reply was meant to be a response to your other ticket here: NRF52832 does not start after power up.

Hello,

If you need to support DFU over BLE and not over UART, you will either have to reduce the size of your application or add an external SPI NOR flash IC to your design to place your secondary slot in.

Typical flash memory layout when using MCUBoot on the 52832 without ext. flash

Best regards,

Vidar
