Installation Steps

Preparing the Source Code and Environment

Get the toolchain, download, and extract it.

Note: The official kendryte toolchain reports a floating-point type incompatibility error, while versions of the RISC-V toolchain prior to 8.2.0 have header file incompatibility issues. (See installation document)

Clone the repository and configure it:

git clone https://github.com/RT-Thread/rt-thread/
cd rt-thread/bsp/k210
scons --menuconfig
source ~/.env/env.sh
pkgs --update

In menuconfig, ensure the following options are correctly set:

RT-Thread online packages --->

peripheral libraries and drivers --->

Kendryte SDK --->

[*] kendryte K210 SDK

RT-Thread Components ---> C++ features

Then open rtconfig.py, find line 18, and replace EXEC_PATH with the bin directory of your extracted toolchain.

Compile the Code

Compile using scons:

scons --exec-path="path/to/toolchain/bin"

Flashing the Image
