History
bunnie 5116d51de5 move kernel UART to DUART port 
using the DUART means we don't get console input on the kernel
(because the DUART is incapable of this) but it's a decent compromise
I think because the DUART is fast and efficient, and mostly we want
it to capture kps?

Eventually we'll need an input mode but for now, this will get us
moving.

Xous Kernel

This contains the core kernel for Xous. It requires a stage 1 loader in order to start up, as it assumes the system is already running in Supervisor mode.

Building

To build the kernel, you will need a riscv32 target for Rust. Possible targets include riscv32i-unknown-none-elf, riscv32imac-unknown-none-elf, or riscv32imac-unknown-xous-elf.

  1. Decide what target you want. For simple, embedded systems this could be riscv32i-unknown-none-elf, and for more complex systems with compressed instructions you could use riscv32imac-unknown-none-elf.
  2. Get Rust. Go to https://rustup.rs/ and follow its instructions.
  3. Install the proper toolchain: rustup target add ${target_arch}
  4. Build the kernel: cargo build --release --target ${target_arch}

Using

To use the kernel, you must package it up into an arguments binary with xous-tools.

Testing

TBD
