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 Jagir,
.spk are one of format for file to download into the module.
To get the toolchain, you should check the following link WP77xx Firmware Release 9 Component
and then browse the page till the tab about “Rebuild Linux Distribution or/and Legato from source”
and select the toolchain you need into this tab,
