Hi Alberto,

this usually also works fine.  Actually there is a toolchain.cmake file, but it is a bit hidden.  But you don't need to reference it directly, because when you source the yocto sdk, it will automatically set the correct environment variables.

But you will need to populate the sdk image with openssl and boost, because these dependencies are not build automatically by everest-core.

Thanks, now it's ok.

another question, I have a yocto distro for another target board and I would cross compile it for this target.

Which is the best way to obtain toolchain.cmake file?

I mean can bitbake sdk using:
bitbake core-image-minimal -c populate_sdk
but it does not generate the toolchain.cmake file.
any tips?

Thanks
Alberto

Hi Alberto,

this can be fixed by updating your everest-core to the latest main version.

There was an issue where everest-core did not fetch the correct version of the "everest-cmake" repository if it wasn't present in the parent directory of everest-core.

This has been fixed about a week ago: https://github.com/EVerest/everest-core/commit/100be12f27e57e13d15a81810b65484ae56f8bba

I hope this fixes your issue,

Kai
