MPC to protect DDR

I have a project (OMAP L138) that uses theDSPandARMsimultaneous.TheDDRis sharedby bothprocessorsand protectedbyMPU.

It is also possible to configure the MPC module in the DSP BIOS to prevent possible DSP writing on the ARM DDR?

Something like that:

// DDR: 128 MB = 96 MB (ARM) + 32 MB (DSP)

MPC_setBufferPA((Ptr)0xC0000000, 0x06000000, 0, 0);
