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

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.
