k210-example

Set of example applications for the K210

Build

• Requires Rust 1.43
• Requires riscv64gc-unknown-none-elf target
• Requires Kendryte K210 kflash.py

Rust 1.43 is needed due to LLVM requirements for a medium code model and static relocation model in order to produce a binary with a base address suitable for the K210's RISC-V architecture.

rustup target add riscv64gc-unknown-none-elf
rustup component add llvm-tools-preview
cargo install cargo-binutils

Release

# Maixduino
cargo build --release --examples --features maixduino
# Other
cargo build --release --examples --features maix

Flash

To build an example and flash using kflash

• You may need to specify a COM/tty port using -p
  • COM8 (Windows)
  • /dev/ttyS8 (Linux)
• You may need to specify a different board using -B
  • kd233
  • dan
  • bit
  • bit_mic
