Hi.

I have an STM microcontroller and a CH582F on my PCB board. I want to update the CH582F firmware via serial interface (UART) using the built-in bootloader, as WCHISPTool does. Can I get the protocol of this bootloader? And code examples?

內(nèi)置BOOT的協(xié)議不提供。

你這里是需要通過(guò)ST的芯片通過(guò)串口升級(jí)CH582，可以通過(guò)IAP升級(jí)，自定義升級(jí)協(xié)議。例程是通過(guò)上位機(jī)完成串口IAP升級(jí)，可以參考：
