Part Number: TMS320F280025
"Our control board features one F280025 MCU and two F2800156 MCUs, all sharing the same 3.3V rail. Because all three MCUs are powered simultaneously, we frequently encounter failures when attempting to flash a specific MCU individually using an XDS110 programmer. Even when providing an additional external power supply to the XDS110 to create a dual-supply setup, failures still occur intermittently. Do you have any suggestions for improving this situation?"
