TIEVM-HV-1PH-DCAC: TIEVM-HV-1PH-DCAC control card change from TMDSCNCD280049C to TMDSCNCD280039C

Hello:

I am working on building the prototype for TIEVM-HV-1PH-DCAC Current mode inverter. It requires TMDSCNCD280049C control card but while I was testing it, I accidentally gave 15V to the PWM output pin and I think the main chip 280049C is damaged. I have another control card TMDSCNCD280039C which uses a similar MCU and I would like to change the Pin numbers on the CCS firmware to be able to use this card instead of TMDSCNCD280049C. I tried changing the DEVICE_GPIO pin numbers in the device.h file and the gridconnectedinvlclfltr_user_settings.h file but it does not seem to work. I also changed the device from the main system configuration device button from TMS320F280049C to TMS320F280039C. Also changed the mcu in the Target Configuration file. None of them seem to work. I can rebuild the project with the new MCU and also can upload the firmware using the Debug but when I try to test it, nothing works. I can not even turn the relay on.  I would like to know what should I do to be able to use the TMDSCNCD280039C control card.

My second question is, If I replace the FS280049C MCU in the damaged Control card, would it work?

Thank you.

    First, can we start by specifying which firmware you are using? There are multiple CCS projects included as part of the DPSDK. Which are you using from this list?

    Second, there are pin differences between the F280049c and F280039c controlCARD. Are you aware of those differences and have you identified the necessary pinout changes to use the F280039c controlCARD? I would recommend leveraging the controlCARD pinout sheets located in c2000ware.

    Assuming the only damaged component in your setup was the controlCARD, then yes.
