RAM access protection in MPC5746R

[kiranmuniraju]

Hi,

We need to ensure only particular software functions get the Read/Write permission into a block of RAM memory.As we looked into the reference manual, we think we have to use MPU or SMPU  modules to restrict access permissions.

I am new to SMPU module please help on this.If possible you can share some sample code snippets.

Thanks and Regards,

Kiran M

Hi,

Yes, you will use SMPU. All necessary details are described in reference manual.

Just give it some time it is not so hard to understand it.

Here is the application example.
