Run this somewhere:
wget https://s3.amazonaws.com/builds.tessel.io/t2/OpenWRT+SDK/OpenWrt-SDK-ramips-mt7620_gcc-4.8-linaro_uClibc-0.9.33.2.Darwin-x86_64.tar.bz2
tar -xf OpenWrt-SDK-ramips-mt7620_gcc-4.8-linaro_uClibc-0.9.33.2.Darwin-x86_64.tar.bz2
Change into that directory. Run mkdir -p ~/tessel/sdk/darwin/
, then run cp -rf OpenWrt-SDK*/staging_dir/* ~/tessel/sdk/darwin/
.
Save this as /usr/local/bin/t2-run-rust
