Unable to build toolchain for the customized build


We are trying to generate the toolchain for our customized yocto build on WP7608.
To do that followed the below steps

  • Built the yocto with our changes like added the mosquitto library etc.

  • After getting the final image, tried to generate the toolchain or SDK with below command

bitbake linux-quic -C populate_sdk

But as per yocto project manual we suppose to get the sdk directory in /build_bin/tmp/deploy with .sh file to install the toolchain on any PC but it is not generating these files.

One more way we tried is

bitbake meta-toolchain

But we didnt get the expected result.

Is this correct way to generate the toolchain?
If not, How to generate the toolchain with WP7608 build?
