I will test that I can use this
bootloader_settings.hex
as described here
to convince the bootloader that it has an valid application

Please see for the bootloader migrated to v6

github.com/.../master_v6

However the following change to enabling installing a bootable application using nrfjprog causes the bootloader to exceed the size allowed.

bootloader_util_arm.c

-uint8_t  m_boot_settings[CODE_PAGE_SIZE] __attribute__((at(BOOTLOADER_SETTINGS_ADDRESS))) __attribute__((used));          
-uint32_t m_uicr_bootloader_start_address __attribute__((at(NRF_UICR_BOOT_START_ADDRESS))) = BOOTLOADER_REGION_START;      
+const uint8_t  m_boot_settings[CODE_PAGE_SIZE] __attribute__((at(BOOTLOADER_SETTINGS_ADDRESS))) __attribute__((used)) = {BANK_VALID_APP};       
+const uint32_t m_uicr_bootloader_start_address __attribute__((at(NRF_UICR_BOOT_START_ADDRESS))) = BOOTLOADER_REGION_START;

To see the change compare branch master_v6 and branch jtag_bootable_v6

I have also uploaded another branch pin_bypass which advertise for 60s bonds for 5mins or bypasses the dfu and directly launches the application if a pin is sensed low.

I did my migration from scratch
please see
github.com/.../master_v6
This compiles into the bootloader rom space.
