Openrisc cross-compile tool-chain

To be able to compile programs for the Virtual prototypes based on an/dual OpenRISC CPU(s) running on the GECKO5Education boards, we are going to use a gcc-cross-compile tool-chain. As the OpenRISC used implements a custom instruction interface, the standard toolchain needs to be patched to allow for the required assembly instructions.

The cross-compile tool-chain can be installed and run on linux, macOS, and windows.

If you want to set-up the tools, follow the instructions for your operating system:

• linux

• macOS

• Windows WSL

• Windows native

Important: The cross-compile toolchain that you can download for the or1k will not do, as it does not incorporate the extra assembly instructions for the OR1300 and OR1420 as used in the courses!
