CH55xtool
=========
Tool for CH55x flashing [from here](https://github.com/MarsTechHAN/ch552tool), rewritten in C.
```
Usage: ch55tool [args]
Where args are:
-P, --pidfile=arg pidfile (default: /tmp/testcmdlnopts.pid)
-b, --binname=arg name of binary file to flash
-d, --dontrestart don't reset MCU after writing
-h, --help show this help
