Example of CONFIG_MCUBOOT_BUILD_STRATEGY_USE_HEX_FILE usage

[flaik-wayne]

Hi,

I have read the thread here:  specify MCUBOOT project or build out of ncs repo which implies that this config option might not work?

Does it work? I would like to build mcuboot and then always use the same binary for future releases - this way, all our devices will be using the same copy of mcuboot.

I first built using the default strategy, then I copied build/mcuboot/zephyr/zephyr.hex to eg my home directory.

Then I set

CONFIG_MCUBOOT_BUILD_STRATEGY_USE_HEX_FILE=y
CONFIG_MCUBOOT_HEX_FILE="/home/wayne/mcuboot.hex"

Then I deleted build directory and rebuilt it as before - it "builds", but the resulting build is broken.

Does this work? How should it be setup? I am using NCS v1.8.0 due to AT&T compliance.

Hi Devzone,

I would love a working answer to this as well!

When I try to configure my project to use a prebuilt hex file, I get the following errors at build time.

Thanks!
