We have a third party group that is going to cross compile their proprietary application and library for us. I have pointed them to the Toolchain section here: https://developer.toradex.com/knowledge-base/build-u-boot-and-linux-kernel-from-source-code#Toolchain. I don’t think they had any trouble getting Linaro installed.
They have asked what other makefile flags need to be set, and I’m not exactly sure?
