TMS320F28033: Software developed on superset F280037CSPT 100% compatible with F280033SPT?

Part Number: TMS320F28033

Dear Champs,

I am asking this for a customer.

The user wants to use 48-pin F280033SPT, but because sample availability, they can only use superset F280037CSPT.

Therefore, they are asking if they can develop codes on F280037CSPT and then 100% same as that for F280033SPT when F280033SPT is available?

In my understanding,

1. They should avoid use part ID.

2. They should avoid using any peripherals that F280033SPT does not have.

3. They should use the .cmd file for F280033SPT.

However, I don't see the specific F280033SPT .cmd in the latest CCS11.1 folder C:\TI\ccs1110\ccs\ccs_base\c2000\include.

Would you please help specify where it is?

4. Is there anything else the user has to be aware in order to use the same codes from superset F280037CSPT to F280033SPT?

    Hi Wayne,

    Sorry about the delay. In addition to what you have already indicated, below are the additional differences:

    1. No CLA on 33
    2. No CLB variant on 33
    3. 128KB Flash on 33 and 256KB Flash on 37
    4. No Message RAM

    If they don't plan to use the CLA and CLB then no issues. The flash is also half the size as indicated above.

    I don't think we provide a GPN specific linker command file but let me double check with the software team and get back.

    Dear Frank,

    I saw specific .cmd like F280034 in CCS 11.1 folder, C:\TI\ccs1110\ccs\ccs_base\c2000\include, but I just do not found that for F280033.

    This is why I am confused.

    Hi Wayne,

    My mistake. I checked with the software team and we do indeed provide GPN specific cmd files in the location you specified. The absence of the cmd file for F280033 is a miss and will be included in the next release. However you can use F280034 cmd file for F280033 as the only difference between those 2 variants is the missing CLA on F280033. Let us know if you have more questions.
