WeAct Studio CH32X035F8U6 board

[nanikjava]

Playing around with the blink sample from https://github.com/cnlohr/ch32v003fun/ and managed to compile the code. Tried using wchisp to flash but getting Error: Verify failed, mismatch. Flashing procedure uses the following command:

wchisp  -v flash ./devboards/ch32v003fun/examples_x035/blink/blink.elf

here is the full log

I observed the same output when flashing the WeAct CH32X035 board.

I think the problem is the error message is unclear. e.g. when flashing with the WCHISPStudio, it indicates the error "Read-Protect is enabled,Please disable code-protect first!".

Disabling code-protect requires a WCH-LinkE (or WCH-LinkW). wlink should be able to do code-unprotect.

Disabling code-protect requires a WCH-LinkE (or WCH-LinkW). wlink should be able to do code-unprotect.

@rgoulter Do you know what is the full command to run using wlink ?

[rgoulter]

With a WCH-LinkE, with the SWCLK and SWDIO pins connected to the CH32X035 (& the CH32X035 powered; e.g. plugged in by USB),

using wlink should be as simple as:

wlink unprotect

Then you can run wchisp flash as usual. (Also, wlink protect will enable the protection again, should you want that).

However, wlink flash <path to firmware> also will also work. Since that doesn't require unplugging/plugging the USB cable (while holding the boot button), it's more convenient than using wchisp.

Also, to be clear: the "WCH-LinkE or WCH-LinkW" is per the WCH Link User manual. https://www.wch-ic.com/downloads/WCH-LinkUserManual_PDF.html -- If you try with a WCH-Link (e.g. WeAct's WCH-Link board), I observed the WCH Link Utility software reports that it isn't compatible.
