Re: pi cross compilation

Alberto Merciai

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?

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.

I hope this fixes your issue,
