Access to peripherals in UserMode when K82 MPU is enabled

Hi !

 

It is not so clear from documentation if K82 MPU can be configured for access to simple peripherals (LPUART0 )

in UserMode. All trials to configure LPUART address space in MPU for read/write space dosn't have any effect and simple read of DATA register cause BusFault.

Not all ARM can grant access for this area in UserMode.

 

But what about K82 ?

Does it possible to configure K82 MPU if in UserMode to have access to LPUART0 and i2C address space ?

 

Regards,

Eugene
