Hi

Do you plan on supporting latest versions of rm2? I have verison 3.20.0.92 and am seeing this error when I try to install toltec-

INFO: Bootstrapping Opkg
wget: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory
ERROR: Could not fetch opkg, make sure you have a stable Wi-Fi connection
