Overview
The Microchip M2GL025 board is an IGLOO2 FPGA based development board.
The Mi-V RISC-V soft CPU can be deployed on the MGL025 board.
More information can be found on

Programming and debugging
.. zephyr:board-supported-runners::
Applications for the m2gl025_miv board configuration can be built as usual
(see :ref:build_an_application):
.. zephyr-app-commands:: :board: m2gl025_miv :goals: build
In order to upload the application to the device, you'll need OpenOCD and GDB
with RISC-V support.
You can get them as a part of SoftConsole SDK.
Download and installation instructions can be found on
Microchip's SoftConsole website <https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/soc-fpga/softconsole>_.
With the necessary tools installed, you can connect to the board using OpenOCD. To establish an OpenOCD connection run:
.. code-block:: bash
sudo LD_LIBRARY_PATH=<softconsole_path>/openocd/bin
<softconsole_path>/openocd/bin/openocd --file
<softconsole_path>/openocd/share/openocd/scripts/board/microsemi-riscv.cfg
Leave it running, and in a different terminal, use GDB to upload the binary to the board. You can use the RISC-V GDB from a toolchain delivered with SoftConsole SDK.
Here is the GDB terminal command to connect to the device and load the binary:
.. code-block:: console
<softconsole_path>/riscv-unknown-elf-gcc/bin/riscv64-unknown-elf-gdb
-ex "target extended-remote localhost:3333"
-ex "set mem inaccessible-by-default off"
-ex "set arch riscv:rv32"
-ex "set riscv use_compressed_breakpoints no"
-ex "load" <path_to_executable>
