In this case, I suggest that you just use the nRF5 Bootloader instead.

The bootloader does not really care which application it boots.

See One bootloader to rule them all for some discussion on this topic.

Hi Sigurd,

For my system is base on the "ncs/v2.3.0/nrf/applications/nrf_desktop", and we don't have enough space to create 2 app, and our system has only 1 bootloader and 1 app, but our product need to support BT OTA to update the app, so we can only do this in the mcuboot, but in the mcuboot, I try to porting nrf_dfu to the mcuboot, and nrf_dfu need to support the NUS, NUS initialization need to the uart0, now BT and DFU service has bring up, but the NUS uart is not work, so we can't transfer the OTA package.

Hi,

Generally, we do not recommend that you make custom changes to MCUboot source code, as this can compromise its robusteness.

Why do you want to enable UART?
