TMS320F280025C: CAN - BOOTLOADER SOFTWARE RESET ISSUE

Part Number: TMS320F280025C

Tool/software:

Hi!

In the F280025C MCU, the first two sectors are used for the CAN bootloader, and the remaining sectors are for the application.

First, we flashed our bootloader and then our motor control application, and there was no issue.

The issue arises when, during the application, we perform a software reset by sending a CAN message. After the reset, the bootloader runs from sector 1 and waits a few seconds for an update. If no update is received, the old application runs. However, during this process, while the application is running after the software reset, the motor control doesn't function properly (the motor jerks). Interestingly, after a power cycle, this issue does not occur.

What could be the issue here?

Thanks,
Hariprasath

    Hi Hariprasath, 

    Could you provide a little more context about the nature of the issue and the application? What is causing the motor to jerk? Are you able to connect to the device and see what state the software/control algorithms are in? 

    Best,
    Matt
