CCS/TMS320F28379D: How can I make ADC working stand alone!

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

I'm using 'RFFT_ADC' example project via CCS to control TMS320F28379D.

Here is a question.

It works with CCS Debug.

However, after changing A:SW1 switch setting to make it boot from FLASH and reset, it doesn't work.

Do I miss something for ADC setting?

    Hello

    Are you using ~\FPU\v1_50_00_00\examples\fft\2837x_rfft_adc example? Is the debugger connected? If so, in the technical reference manual, look up emulation boot values in the boot code chapter.
    Can you get a blinky LED example working in standalone?

    Best regards
    Chris

    Dear Christopher,
    Thank you for your reply.

    Debugger is connected. I use SCI to check the result in 'Hyperterminal'.
    Data is coming out, and I can see.

    However,

    After Disconnect debugger, it is still working. Also, LED is blinking.

    After reset (turn off and turn on), LED is blinking but, just 0 is coming out.

    Hello,

    I can't think of any particular ADC settings that would cause this. Do you have the watchdog turned on? Is it possible that the device is resetting?

    What example are you using? Are you using the same PLL and flash initialization that the example uses or did you change the code?
