Does anyone know something about it or similar cases?

Is there some registers in HSE clock that can affect the RDP registers?

Is it possible to be a bug in CubeMX?

Or the problem is in my hardware?

Thank you.

Sorry, the complete question is this:

I'm working with a STM32L476 MCU in Atollic, and I have a problem because Read Protection mode.

When I enabled the HSE clock in CubeMX, the MCU was locked and the Atollic showed a Read Protection message. It happened twice and

I can't program it anymore. 

Does anyone know something about it or similar cases?

Is there some registers in HSE clock that can affect the RDP registers?

Is it possible to be a bug in CubeMX?

Or the problem is in my hardware?

Thank you.
