Tried how? Your screen shots, while interesting, don't tell be much about the STM32 end of the issue.

And what USART are you connecting too and how?

You're using BOOT0=High to get into the System Loader?

According to the documentation the VCP uses USART3 PD8/PD9, and that's not supported by the System Loader.

Can you use the ST-LINK?

Can you use the User USB and DFU mode?

Thank you for your reply,

I am using USART1 PA10/PA9 with serial to USB converter according to AN2606.

Yes. I have connected BOOT0 pin high.

Yes, I have found the solution.

The new STM32CUBE Programmer app also supports USART connectivity.​
