How to install toolchain for WP7700 in ubuntu base legato framework?

I have started playing with AirPrime WP7700 module.
But prior to that while building environment, I stuck at “How to install downloaded tool chain for my module ?”.
Because tool chain has .spk extension, So i don’t know how to install it & do further process.
Please let me know ASAP.

Hi JagirMehta,

Not sure which guideline and resource you are referring to?

Per understanding,
.spk is not toolchain but firmware binary to be load on WP7700.
Instead toolchain normally in .sh.
