CCS/TIDA-00663: MSP430FR5969 can't power on

Part Number: TIDA-00663

Tool/software: Code Composer Studio

   Hi, I flash debug version FW via JTAG interface ,and flash is OK, but after remove power then the board can't power on .

I suspect that it runs in debug mode, I build release version FW and flash it to board ,remove power and then power on ,the board restarts incessant.

could you have any advise ? thank you.

  • Hello Wang,

    Are you using CCS to program the board?

    After you program the board, can you use the reset button without removing power?  Does it operate correctly?

    What jumper configuration do you have on your board?

  • Hi:

       I found enable interrupt(__enable_interrupt()) ,it can't power on after turn off power, but disable interrupt it will OK. 

    do you have any advice ?  when disable interrupt the timer interrupt can't occur. and uart port can't put string. these need interrupt.

  •  Hello Eddie LaCost,

         This issue occurs on my own board that following 00663 ,the board can't power on too when press reset button ,

    disable interrupt is OK,but this is wrong. Do you have other advice ? or what's special for 00663 power state ,

    My board don't enter LPM mode.
