Hello,

I’ve an EK-RA4M3 with MCUBOOT using SWAP. I want to create a single hex file for combining mcuboot and application.

I’m assuming I just need to modify the Python script options to create a signed hex instead of a signed binary?

Thank You

    Hi, I'm sure it's possible to modify the Python signing program to output a hex file rather than binary by adding suitable code or pre-existing library. python imgtool.py sign -k mcuboot/root-rsa-2048.pem -v 1.0.0 --header-size 0x200 --align 4 --pad-header --pad-header-size 0x200 merged.hex signed.hRead more

    Hi,

    I’m sure it’s possible to modify the Python signing program to output a hex file rather than binary by adding suitable code or pre-existing library.

    python imgtool.py sign -k mcuboot/root-rsa-2048.pem -v 1.0.0 --header-size 0x200 --align 4 --pad-header --pad-header-size 0x200 merged.hex signed.hex

    In this example, merged.hex is the merged hex file, and signed.hex is the signed hex file that will be created. The –pad-header and –pad- header-size options are used to add padding to the title of the signed hex file, which is required by MCUBOOT.

    Thank You
