Hi @margo ,
Are there any warnings or errors during the build process with ./waf configure --board navigator and ./waf sub?
You’ll need to rebuild the firmware specifically for Navigator using specific toolchain version. rebuild navigator firmware To set up the specific toolchain before building the firmware, use the --toolchain argument with waf.
./waf configure --board Navigator --toolchain /opt/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf
your can download the toolchain from arm toolchain 9.2-2019.12
