+(MPFS025T, MPFS095T, MPFS160T, MPFS250T, MPFS460T)
+
+
+MPFS Toolchain
+==============
+
+A generic RISC-V toolchain can be used to build MPFS projects.
+Like: https://xpack.github.io/riscv-none-embed-gcc or https://github.com/sifive/freedom-tools/releases
+
+
+Booting
+=======
+
+The NuttX port for now relies on HSS bootloader to carry on some hardware initializations.
+
+
+Building and flashing
+=====================
+
+First make sure that ``hss-payload-generator`` is installed.
+Available from: https://github.com/polarfire-soc/hart-software-services
+
+This tool is used to convert the ELF/bin to a compatible HSS payload image
+
+Configure the NuttX project: ``./tools/configure.sh icicle:nsh``
+Run ``make`` to build the project.
+
+Create HSS payload bin::
+
+ hss-payload-generator -v -c hss-nuttx.yml payload.bin
+
+
+Debugging with OpenOCD
+======================
+
+Compatible OpenOCD and configs can be downloaded from:
+https://www.microsemi.com/product-directory/design-tools/4879-softconsole#downloads
+
+
+OpenOCD can then be used::
+
+ openocd -c "set DEVICE MPFS" --file board/microsemi-riscv.cfg
