Protocol for downloading the program into the CH55x

Open ogogon opened this issue 2 years ago • 1 comments

Could you please tell me if there is a document describing the protocol for downloading the program into the CH552? Is this possible only via USB or is it possible through a com-port?

I contacted the manufacturer, but they, to my great surprise, replied that this information was not published. I am somewhat confused - usually manufacturers do not hide such information. I do not see any risks for the manufacturer in disseminating this information.

Thank you for your reply.

This tool here have not been developed for long time and seems to be dead. Check https://github.com/ch32-rs/wchisp instead. There is active development going on and the CH552 should be supported.
