TMS320F280039C: The program cannot run properly after the chip is powered on

Shukai Li

Tool/software:

When testing the program, I used the emulator to program, and the program was able to run normally. However, after the chip power failure, I used the external power supply to power on, the program could not run normally. I would like to ask what might be the cause of this.

Thanks,

Hi Shukai,

Thanks for your patience as I was out of office. Are you still having this issue? What program were you running and what are the details of this power failure? Were you monitoring the supply rails and XRSn while this occurred? It is difficult to guess at what caused this without more information.

Best Regards,

Allison

Hi Allison,

Thanks for your guidance, the problem has been solved for now. I tested it and found that it was a problem the code into RAM.

Thanks,
