Hi,

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?

Thanks
