TMS320F280048C: PROGRAM_ERROR during Device Firmware Upgrade (DFU) command - SCI boot

Part Number: TMS320F280048C

Application loaded on to flash via CCS debug port works fine. I need to dataload the application on to flash via SCI boot on F28004x launchpad board. In the application, RED/GREEN LEDs are made to blink every second.

When I select 'Verify', I see the below messages:

Bit rate /s of transfer was: 6616.629883
Application load successful!
Done waiting for application to download and boot...
SUCCESS of Command
ERROR Status: VERIFY_ERROR
ERROR Address: 0x80000

When I select 'DFU', I see the below messages:

Bit rate /s of transfer was: 7375.351074
Application load successful!
Done waiting for application to download and boot...
SUCCESS of Command
ERROR Status: PROGRAM_ERROR
ERROR Address: 0x7200

I need to understand what could be causing this error.

The application boot file generated using hex utility with options --boot --sci8 --ascii

Let me know if need more information.

Please help. With Regards,

Sandeep
