R12 is not in repository

R12 is not at repository of Studio even refreshing …

How about developer studio in linux version?

I have only win available now.

No idea about windows version for me…
But you can try vmware to see if it works on linux version.

Just have a check in linux version, there is no R12 for WP77.
Probably you need to download the legato source and toolchain here and then install mannually in Developer Studio linux version:

Also you can download the package in LEAF and install it in Developer Studio linux version.
