Overview
|
|
********
|
|
|
|
The Microchip mpfs_icicle board is a PolarFire SoC FPGA based development board with a Microchip MPFS250T fpga device.
|
|
The E51 RISC-V CPU can be deployed on the mpfs_icicle board.
|
|
More information can be found on the `Microchip website <https://www.microchip.com/en-us/product/MPFS250T>`_.

Programming and debugging
|
|
*************************
|
|
|
|
Building
|
|
========
|
|
|
|
Applications for the ``mpfs_icicle`` board configuration can be built as usual
|
|
(see :ref:`build_an_application`):
|
|
|
|
.. zephyr-app-commands::
|
|
:board: mpfs_icicle
|
|
:goals: build
|
|
|
|
To build the default SMP capable variant
|
|
|
|
.. zephyr-app-commands::
|
|
:board: mpfs_icicle/polarfire/smp
|
|
:goals: build
|
|
|
|
Flashing
|
|
========
|
|
|
|
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/programming-and-debug/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:rv64" \
|
|
-ex "set riscv use_compressed_breakpoints no" \
|
|
-ex "load" <path_to_executable>
|
|
|
|
Debugging
