Executing a Post Build Batch File using CMake
Build Environment Details
What I am Trying to Achieve
At the end of my build process, I would like to execute a batch file on the zephyr_final target that signs the final image. This is different than the MCU Boot signature and is a custom proprietary signature. I am unable to change the way in which this image is signed as it must be compatible with existing tools used with my product.
Method in Which I am trying to Achieve
Normally, I would do this using add_custom_command(TARGET target_name POST_BUILD
COMMAND "batchfile.bat" batchfile_arguments)
However, I don't believe that the final zephyr target is within the scope of the top-level CMakeLists.txt file. That said, I do not have a lot of experience with CMake as most of my past development was within the IAR toolchain. It's very possible that I am misinterpreting this.
1. Will I be able to use the add_custom_command() CMake function to execute the batch file? If so, can someone provide an example as to how I would do this and what Target I should be using.
2. Is there a better, more appropriate method for doing this within the Zephyr environment.
Any help or guidance is much appreciated!
I have been using `add_custom_command` to sign my generated images like this:
COMMAND west sign -t imgtool --
COMMENT "Running post-build signing step..."
Note that the command won't trigger without the additional `custom_target`. Also, my source directory is child of `zephyrproject/zephyr`, so I can't say for certain that this will work in your case.
Hi Casey,toggle quoted messageShow quoted text
Did you have a look at the global 'extra_post_build_commands' and
'extra_post_build_byproducts' properties mentioned in
Try searching around the source tree to see how it is used and if you
can adapt it to your needs.
