STM32CubeProgrammer crashes when connect STM32F401CCU6

[Totouan]

I just get a STM32F401CCU6 board (a real one) but now when I try to connect my board on STM32CubeProgrammer the application crahses... and when is unplug my board the application work again fine... 

It also look like my board is stuck in bootloader mode ( only the red led lights up)

I don't know if someone could help me...

Thank you

F401 has a buillt-in bootloader in System ROM. It looks like it's recognized by CubeProgrammer. I frequently use CubeProg with BlackPills - they work (well, one didn't because of wrong soldering of the main crystal - fixed). No matter what kind of problem we get here, CubeProg should not display an empty message. So mu guess is it's a problem with CubeProg installation on this particular computer.

I would suggest to try the same on another computer.

CubeProg is not very reliable. If it works, it works. Frequently it doesn't. Sometimes it cannot start on some computer. Sometimes it reports false problems with the MCU.

Always best to provide a link at the start - so that everyone knows exactly what you're talking about

That's a 3rd-party board - not an ST board - and there's a risk that it may not have a genuine STM32.

Have you contacted RUIZHI for support? Do they claim that it should work with CubeProgrammer?

Do you have that "WeAct" bootloader?

Thank you for your help, I will try what you told me to do

And yes it is written WeAct on the back of the board if it is what you meant.
