Maix Go / K210 stuff
First, get the Kendryte C toolchain and copy or symlink the contents of the
src/ folder to a checkout of https://github.com/sipeed/LicheeDan_K210_examples.git.
Then to build a certain project do:
mkdir build && cd build
cmake .. -DPROJ=<ProjectName> -DTOOLCHAIN=/opt/riscv-toolchain/bin && make
You will get 2 files, build/<ProjectName> and build/<ProjectName>.bin. The former
is an ELF executable, the latter a raw binary that can be flashed or written to
0x80000000 in SRAM and directly executed.

Projects
glyph_mapping
Variation of the DVP sample that processes the camera input through a simple
DOS 8×8 font glyph-mapping algorithm and shows it on the display.
dump_otp
Dumps the contents of the OTP (One-Time Programmable memory) of the K210 CPU to serial output in Intel HEX format.
rust/k210-console
Console emulator written in Rust for the Maix Go.
Barely functional at the moment. This is really a test for some functionality like SPI and driving the display from Rust, and for playing with Rust RISC-V 64 in general.
ROM re'ing
Annotated radare2 config files for the Boot ROM and OTP can be found under r2.
Other projects
Some other interesting K210-based projects and demos:
-
accelerometer - Example of using the MSA300 accelerometer on the MAIX Go board, by GitJer
-
quake1 - Quake 1 on K210. Requires wiring up a PS2 controller.
-
doom1 - Doom 1 on K210
