Migrating from PIC24FJ256GB210 to PIC24EP512GU810

Hi all,
I'm trying to migrate from a functionnal board with PIC24FJ256GB210 to PIC24EP512GU810.
Since the PIC24EP512GU810 is 3.75 faster than the PIC24FJ256GB210, the aim of this modification is to get faster transition between screens.
Pins comparision is totally equivalent.
I also use a graphic controller S1D13517 in 16bits PMP interface.
what are the minimal modifications to take in account to get the graphic to display ?

    Are you using DMA?

    On the PIC24FJ256GB210, I was using the EPMP port and now trying to make it work with the PMP port on the PIC24EP512GU810. So no DMA is used.
    Is it a major modification to make it work with DMA ?

    Not really.
     
    DMA+double buffering.
     
    Download from MC: Section 38. Direct Memory Access (DMA) (Part III)
