开发板重新上电后没反应。

Can you provide any more details about the board and MCU model? Also, please write in English, if possible.
Please provide debug output by running stcgal with the -D option.
This issue perhaps has same problem as my issue. there just some chinese like run: raise error: run: stay the cycle waiting: restart develope board and have no reaction. System is OSX 10

I have the same problem. Packet checksum mismatch.

As luck i have two STC MCU, one is STC89C52, another is STC90C516RD+. the experiment show that STC90C516RD+ is all right and can write success, the STC89C52 show the same error: Protocol error: packet checksum mismatch. the os is macOS High Sierra 10.13.6.
so i think i need buy another STC89C52RC to replace STC89C52. maybe it will work normal.
Hi there. @grigorig @ Thanks for your efforts.
Same issue for me.

CH340C, STC89C52, macOS 10.13.6
In my case, stcgal is not working on Windows as well with same error.
The MCU works well while using STC-ISP on windows VM.
Same issue for me.

If any one of you is still here: newer STC89 devices have a newer bootloader with some protocol changes. Please try again with the latest release and specify the "stc89a" protocol manually.
