at last I found the reason, Many times the programming chips on the power up state may cause the application to fail to output RTT.RTT output can be restored by power cut reset chip,This is a phenomenon that has not been found in SDK14.0-14.2

Hi Bevis,

It's a known issue that RTT logging in bootloader and in application may not work together. You can have a look at this case and this case.

I don't understand the 2nd question you have ? If you don't want to protect your MBR and bootloader you can comment out the code, but you risk the chance that your application (or harmful application) may mess up with the MBR/bootloader and brick the device.

PS： All the nrf_bootloader_flash_protect functions inside the nrf_bootloader_app_start_final function have been annotated by me. Should they not be written by flash? Or where did I miss it?
