HowTo: mcuboot (nxp port) with custom keys

[StWandl]

Hello,

unfortunately issues are disabled in the mcuboot repository, so I am asking it here.

We want to use the NXP fork of mcuboot for our new products, which include different MCXA/N controllers. We are able to integrate it into our build system and simple examples are already running.

Unfortunately it seems like it is not possible to use other keys than those included in the repository.
The file keys.c includes the appropriate key from the "keys" subdirectory.
Of course you don't want to use those publicly accessible keys in production.

Is it possible to use my own keys without modifying any files from the nxp-mcuboot repository?
It seems not possible, because in the CMakeLists.txt the keys.c source is always added to the build, which includes the keys from the "keys" subdirectory.

Thank you!

Hi, currently the only way is to either change the code or replace the file it loads. It is meant to be an example but I understand an option like this would be useful when deriving a production code from this example. I will put this as TODO for a future release.
