Dependencies

• k210 board or qemu-system-riscv64
• RISC-V Toolchain: riscv-gnu-toolchain

Installation

git clone https://github.com/SKTT1Ryze/xv6-k210

Build

First you need to connect your k210 board to your PC.
And check the USB serial port:

ls /dev/ | grep USB

In my situation it will be ttyUSB0

cd xv6-k210
make build

Run on k210 board

make run

Sometimes you should change the USB serial port:

make run k210-serialport=`Your-USB-port`(default by ttyUSB0)

Ps: Most of the k210-port in Linux is ttyUSB0, if you use Windows or Mac OS, this doc may help you: maixpy-doc

Run on qemu-system-riscv64

First make sure you have the qemu-system-riscv64 on your system.
Then run the command:

make run platform=qemu

Ps: Press Ctrl + A then X to quit qemu. Besides, file system and uesr programs are available on qemu. More details here.
