Protocol for downloading the program into the CH55x #17

Open ogogon opened 1 year ago

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.
