Download error "Fault writing memory" with minichlink option -U

xsrf commented 1 year ago

Hey, I've got a bare CH32V003A4M6 with just GND, 3V3 and SWIO connected to the WCH-Link programmer. When trying to upload the bootloader, I'm getting these errors:

Uploading other code, like the blink example, works. After the errors, the previous code still runs.

minichlink.exe -? doesn't tell me what -B and -U do, but when I try them it won't say its an unknown command, so 🤷‍♂️

However, removing -U results in Image written. and it looks like it worked - at least the blink code now is delayed when powered on. But so far I can't get it to enumerate via USB.

Try other demos other than the bootloader. The bootloader is jank.

Do you know what -U does? Why do you use it?
