Wio Lite RISC-V

Quick start with the Wio Lite RISC-V board

Quickstart

Dependencies

• rust-std components (pre-compiled core crate) for the RISC-V target. Run:

rustup target add riscv32imac-unknown-none-elf

• dfu-util

• objcopy from RISC-V toolchain from e.g riscv-binutils-gdb

Building

cargo build --examples --release --all-features

Using dfu-util for Flashing

1. Extract the binary

riscv-nuclei-elf-objcopy -O binary target/riscv32imac-unknown-none-elf/release/blinky firmware.bin

2. Flash using dfu-util:

dfu-util -a 0 -s 0x08000000:leave -D firmware.bin
