wchisp flash is not work as expected

[hc7]

Hello, please explain why I can't flash wch583:

I can reproduce this too.
This is a regression. 🥲

[andelf]

@hc7 I used wchisp to successfully flash my CH582. So this must be some bug introduced recently.

After I downloaded the windows version of WCHISPTool.
The WCHISPTool fails too!!

Then I realized, this is caused by CFG flags.
When CFG flag is 4d0fff4f, then you can flash the MCU with wchisp.
When CFG flag is 4FFF0FD5, then the verify process always fails. 🤯

I changed default reset value of CFG flag recently to help developing a wch-link tool, and thus introduced a wrong cfg value.

[andelf]

That's OK. your devices should be successfully flashed.
The error is caused by an unwrap() call in drop(). I'll fix it soon.

[hc7]

It looks like I haven't flash successfully by wchisp but yes wchisptool can't flash too. But wchisptool can reset bits to working state and then flash.
When enable simulate interface there is no flash.

When enable code and data protection mode - it is possible to flash and verify.

Now configuration is 18:11:44 [INFO] Current config registers: ffffffffffffffff4f3f0f4d

[andelf]

ffffffffffffffff4f3f0f4d should be a valid state.

Sadly I'm having the same problem with aa CH32V307, after flashing, verification just fails. Latest commit.

@maxgerhardt The official version has an extra "Deprotect succeed" log.
Could you try wchisp config reset then flash?

[maxgerhardt]

Sadly the same: https://pastebin.com/ubUAUHW6

🥲 I'll check this following Monday.
Currently, I have no CH32V307 at hand.
