Booting
=======
-The NuttX port for now relies on HSS bootloader to carry on some hardware
initializations.
+The NuttX works as a standalone operating system that may initialize all the
required clocks and
+peripherals including DDR memory. Alternatively, the vendor's HSS bootloader
may be used instead to
+perform all the initialization steps.
Building and flashing
=====================
+Configure the NuttX project: ``./tools/configure.sh icicle:nsh``
+Run ``make`` to build the project.
+
+If NuttX is built as a standalone OS with the config option
CONFIG_MPFS_BOOTLOADER set, it's important
+to note that the image size is very limited: only (128K - 256) bytes. 256
bytes are reserved for the
+header that must be prepended into the NuttX binary. This binary is called
hss-envm-wrapper-bm1-dummySbic.bin
+and may be found from the vendor's HSS implementation. Moreover, after
prepending the 256-byte header,
+the LMA section needs to be adjusted, for example::
+
+ riscv64-unknown-elf-objcopy -I binary -O ihex --change-section-lma
*+0x20220000 nuttx.bin nuttx.hex
+
+The output binary nuttx.hex may be flashed with the LiberoSoc tool.
+The tool is available from:
https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/fpga/libero-software-later-versions#Documents%20and%20Downloads
+
+There's an alternative way to use NuttX, without the CONFIG_MPFS_BOOTLOADER
option set. This expects the
+HSS bootloader sets up the system (memories, caches, initializes clocks etc.).
First make sure that ``hss-payload-generator`` is installed.
