Topic: Intel hex format

Hi,

I'm looking for information on supported image file formats.

I don't see any mention of image file formats anywhere in the documentation but "Signing.md" provides only examples for binary images.

Is Intel hex format supported as well?

Thanks,
Galadrius

Re: Intel hex format

Hi Galadrius,

I've moved this discussion to the wolfBoot sub-forum, as you were referencing the wolfBoot documentation:
https://github.com/wolfSSL/wolfBoot/blo … Signing.md

I'll check with the team to see what image formats are supported by wolfBoot.

Thanks,
Eric

Re: Intel hex format

Hi Galadrius,

wolfBoot does not support the Intel HEX format directly, but it can be easily converted to bin via objcopy:
e.g. on arm-cortex:

arm-none-eabi-objcopy --input-target=ihex --output-target=binary firmware_v1.hex firmware_v1.bin
