TMS320F28032: Anything to take care using same binary for F28034 ?

Part Number: TMS320F28032

Hi Champs!

Customer uses TMS320F28032PNT. Due to delivery issues, we tend to use TMS320F28034PNT with x2 flash.

For flashing he uses serial bootloader and want to reuse existing binary of 280032.

Question:

Anything to mind here, even project cannot be rebuild to F28034 target ?

    The binaries should load as-is on an erased device and run the same as before.

    If customer had a certain sector that they have hard coded to be erased later on (without reprogramming the entire device) they would need to be mindful that the sector sizes are 2x on the F28034 compared to the 28032.  So both devices have 8 sectors, for instance on the F28032 if they had issued an erase command to Sector H, this would cover addresses 0x3F0000-0x3F0FFF.  However, on a F28034 Sector H corresponds to 0x3E8000-0x3E9FFF, so erasing Sector H here would not erase the correct addresses.  For this they would have to erase Sector D.

    The above may not be applicable to the customer system, but wanted to point it out in case.

    Best,

    Matthew
