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.
secp256k1_{tests,bench}
Run tests and benchmarks for the secp256k1 elliptic curve cryptographic library on this RISC-V CPU.
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.
rust/mandelbrot
Mandelbrot fractal zoom.
rust/game-of-life
"Game of life" cellular automata simulation. The state can be manipulated through the touch screen. The amount of pressure applied determines the radius of the state change.
ROM re'ing
Annotated radare2 config files for the Boot ROM and OTP can be found under r2.
