Build zephyr with Metaware toolchain
I'm trying to build the hello_world example from Zephyr 2.4.0 release to the ARC HSDK board using my installed MetaWare toolchain, but the build fails.
I did so by setting the environment variable ZEPHYR_TOOLCHAIN_VARIANT to arcmwdt and ARCMWDT_TOOLCHAIN_PATH to $METAWARE_ROOT/../ per the instructions in the Zephyr documentation.
It seems that the code is compiled for the ARC EM processor instead of the ARC HS, and at some point the compilation fails.
Does anyone have any experience in building with the Metaware toolchain for an ARC EVK board that can shed some light here?
