How to produce merged-internal.hex

[lynxD]

In release 1.2.0 merged-internal.hex file is provided. I can't find any documentation/script on procedure to produce it. Can anyone point me to it/write it down?

The additional files in release 1.2.0 are the files I generated and sent to the factory for the production of the new batch of PineTimes:

• merged-internal.hex contains the bootloader + infinitime (to be loaded in the internal memory of the nrf52)
• spinor.bin contains the recovery firmware (to be flashed in the internal SPI flash memory).

I generated these files manually (but it would be nice if they were generated automatically by CMake) :

• merged-internal.hex :

  • Convert pinetime-mcuboot-app-image-x.y.z.bin to an hex file using objcopy (do not forget the option to specify the offset at 0x8000).
  • Merge this hex file with the one containing the bootloader. For this, I used merghex from the NRF CLI tools.

• spinor.bin :

  • Convert the file pinetime-mcuboot-recovery-image-1.3.99.bin to hex using objcopy. The offset is 0x00.

I've successfully generated merged-internal.hex and spinor.bin. Thx! The commands I've used: merged-internal.hex:

 arm-none-eabi-objcopy --input-target=binary --output-target=ihex --change-section-address '*=0x8000' build/output/src/pinetime-mcuboot-app-image-1.3.0.bin build/output/src/pinetime-mcuboot-app-image-1.3.0.hex
path/to/nRF-cli/nRF-Command-Line-Tools_10_13_0_Linux64/mergehex/mergehex --merge build/output/src/pinetime-mcuboot-app-image-1.3.0.hex ~/tmp/bootloader.hex --output build/merged-internal.hex

spinor.bin:

arm-none-eabi-objcopy --input-target=binary --output-target=ihex build/output/src/pinetime-mcuboot-recovery-image-1.3.0.bin build/output/src/spinor.bin

I can add that to build logic. I just need to know how do You want it go about getting bootloader? Add repo as a submodule(specific commit) and build it? Expect a file to be placed somewhere and not build by default? Add a golden binary to git?
