umi 编译步骤

[asmcos]

编译

git clone https://github.com/js2xxx/umi/
cd umi
cargo install cargo-binutils
cp sdcard-comp2.img third-party/img/sdcard-comp2.img
make run

#查看结果
more debug/qemu.log

[asmcos]

升级最新 rustc

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

[asmcos]

sudo aptitude install qemu-system-riscv64

[asmcos]

umi支持fat32文件系统格式，如何制作 一个fat32的img？

1. dd if=/dev/zero of=disk1.img bs=1024 count=50k
2. mkfs.vfat -F 32 disk1.img
3. sudo mount disk1.img mnt
   将需要的文件复制到mnt 目录即可。
   上述制作 是50M大小的磁盘。可以通过修改count来设置磁盘空间
