TMS320F28376S: Replacing c2000 28376S with 28377S

Part Number: TMS320F28376S
Other Parts Discussed in Thread: UNIFLASH

Dear sir ,

We have controller that is based on 28376SZWT , due to component shortage we are considering to assemble 28377SZWT (which we able to buy).

I have looked at the datasheet , and beside the fact that 28377S has more RAM and FLASH , i think there is no issue  to run our software (build for 28376S) on the 28377S  , without any modification.

Can you advise on this ?

    Eyal,

    There should be no modification needed to run the F28376S binary on F28377S, unless your software is looking for a specific value in the PARTID register.

    The flashing tool may require a new configuration, but the firmware image should be compatible.

    hi tommy ,

    Thank for the response  , i am glad to hear no software modification are required.

    Additional question  , we are programming the target by  command line  (created by UniFlash)  , the UniFlash project 

    is based on target configuration for 28376S , do you think we will able to flash 28377S as well  without modification ?  or we will have to modify the project to target 28377S.

    Thanks , Eyal.

    Eyal,

    I suspect that you will need to modify the UniFlash target device to F28377S so that the PARTID bits match, but the firmware image itself will not need to be changed.

    You can also try to use the unmodified F28376S flow on a F28377S test system to see if it works. There shouldn't be any harm in trying this.
