Hi.
I'm having an issue with the error: failed to erase memory on STM32F407.
I'm using the board https://github.com/mcauser/BLACK_F407VE
and the debugger https://github.com/WeActStudio/WeActStudio.MiniDebugger.
and the original STM32F407VET6 chip.
Yesterday there was no issue, but today when I tried to continue my project, the problem appeared. I have set the SWD frequency from Auto to 100 kHz. At some point, it worked with BT0 = 0 and BT1 = 0 after several attempts of pressing the reset button before starting the debug. I have replaced the debugger twice and tried it on the same chip type on a different board, and it worked. However, it did not work on the chip on my project board. I tried it with the STM32Programmer, and the same problem occurred—it could not erase during download. Strangely, full chip erasure could be done, and the connection was normal with no issues.

If I change the frequency to 100 kHz, this problem occurs.

I experienced the same error on the same chip a month ago, and I tried closing the application and reopening it, which worked. However, this time it was different; it didn't work. I tried upgrading from STM32CubeIDE 1.19.0 to 2.0.0, but the problem remained the same.
Is my chip damaged?
Thank you :)
