===========
.. include:: README.txt
:literal:
.. tags:: arch:riscv, experimental
.. include:: README-qemu.txt
:literal:
.. todo::
There is currently no support for the FPU, ELF-based file applications,
protected mode with PMP or RISC-V User mode.
Installation
============
Download and install the toolchain from
https://occ.t-head.cn/community/download.
If you're planning on using NuttX in QEMU for this board, install QEMU from
https://occ.t-head.cn/community/download.
Building NuttX
==============
.. note::
If configuring to run on QEMU, enable the option ``CONFIG_C906_WITH_QEMU=y``
in the Kconfig menu (``make menuconfig``).
Flashing
========
Run NuttX by downloading the produced ELF to RAM via a HW debugger.
If running on QEMU, first modify the config file ``smarth_906_cfg.xml`` to
enlarge the RAM size with this patch:
.. code:: diff
- <mem name="smart_inst_mem" addr="0x0" size ="0x00020000" attr ="MEM_RAM"></mem>
+ <mem name="smart_inst_mem" addr="0x0" size ="0x00400000" attr ="MEM_RAM"></mem>
...
- smart_inst_mem, Start: 0x0, Length: 0x20000
+ smart_inst_mem, Start: 0x0, Length: 0x400000
Then, you can launch QEMU using the following command:
.. code:: console
$ ./cskysim -soc $PATH_TO_SOCCFG/smarth_906_cfg.xml -nographic -kernel $PATH_TO_NUTTX_BUILD_DIR/nuttx
Configurations
==============
You can select a configuration using the following command:
.. code:: console
$ ./tools/configure.sh smartl-c906:<config>
Where ``<config>`` is one of the configurations listed below.
nsh
---
A simple configuration with the NSH shell.
