The addresses are already included in the bootloader hex file.

To ensure that the bootloader start address gets set correctly in the UICR/MBR??

How to set？

To ensure that the bootloader start address gets set correctly in the UICR/MBR, try to do a chiperase first, then re-program the Softdevice and your updated bootloader.

I modified this, but the program cannot run. Do I still need to modify it?

Hello,

You can allocated more space to the bootloader by reducing the start address of the bootloader in flash. Please see the pca10056_ble_debug configuration for refence. This project sets the start address to 0xf1000 which gives the bootloader 0xd000 bytes.

Best regards,
