yoctotoolchain

How to generate cross-toolchain for the platform with Yocto?

I am relatively new to Yocto.

I have a Yocto project which builds properly an image for sm2s-imx8mp machine. helloworld application is built as part of the image. From the logs I see that arm-poky-linux-gnueabi-gcc cross compiler was used to compile helloworld.

Now I have to use the toolchain (which was used by Yocto to compile the helloworld) also outside the Yocto to compile other apps.

The question is: what is the correct way to obtain the toolchain package for the sm2s-imx8mp machine with Yocto?

Does Yocto have something like bitbake build_toolchain command to obtain the toolchain?

Solution

  • As comment suggested, to build SDK from Yocto, you should use:

    bitbake image_name -c populate_sdk

    and after build is completed, you will find your SDK in: build/tmp/deploy/sdk
