TMS320F28388D: Adding Checksum to hex format (.bin) file using hex2000 or any other Tool?

Tool/software:

We are working on developing Bootloader for upgrading the firmware over Ethercat protocol using TMS320f28388d development board, For this we are using Hexc2000 utility to convert .out file to hex format (.bin) file.

Now we need to add checksum for this hex file (.bin) at the end of the file. So how can we do it automatically during hex file conversion through hex2000? is there any Tool or using CCS compiler can we achieve it?

Please suggest any solution for the above.

Thank you.
