DesignWare ARC MetaWare Development Toolkit (MWDT)

1. You need to have ARC MWDT installed on your host.

2. Set these environment variables:

   • Set ZEPHYR_TOOLCHAIN_VARIANT to arcmwdt.

   • Set ARCMWDT_TOOLCHAIN_PATH to the toolchain installation directory. MWDT installation provides METAWARE_ROOT so simply set ARCMWDT_TOOLCHAIN_PATH to $METAWARE_ROOT/../ (Linux) or %METAWARE_ROOT%\..\ (Windows)

3. To check that you have set these variables correctly in your current environment, follow these example shell sessions (the ARCMWDT_TOOLCHAIN_PATH values may be different on your system):

   # Linux:
   $ echo $ZEPHYR_TOOLCHAIN_VARIANT
   arcmwdt
   $ echo $ARCMWDT_TOOLCHAIN_PATH
   /home/you/ARC/MWDT_2019.12/
   
   # Windows:
   > echo %ZEPHYR_TOOLCHAIN_VARIANT%
   arcmwdt
   > echo %ARCMWDT_TOOLCHAIN_PATH%
   C:\ARC\MWDT_2019.12\
