海思 SLE 芯片 Linux 烧录

海思官方只提供了 Windows 下的烧录工具 BurnTool，支持串口，USB，JLINK，网口等方式，但无法在 Linux 下烧录。

有人根据开源出来的文档和源码，逆向出 ws63flash，可以在 Linux 等全平台以串口方式烧录。虽然其名字为 ws63，但其同样支持 fwpkg 打包的 BS21 芯片。

安装 ws63flash

$ wget https://github.com/goodspeed34/ws63flash/releases/download/v0.3.1/ws63flash_0.3.1-1_amd64.deb
$ sudo apt install ./ws63flash_0.3.1-1_amd64.deb

使用

$ sudo ws63flash \
--flash /dev/ttyUSB0 \
--baud 500000 \
~/src/fbb_bs2x/src/tools/pkg/fwpkg/bs21e/bs21e_all.fwpkg
