Part Number: TMS320F280049

It's always blocking at InitSysCtrl() when we porting sunspec project to TMS320F280049 according to

Where should I take attention on crystal HW and setting when porting it from F28379D to F20049? Thanks.

Hi Daniel,

Are you porting to the F28004x LaunchPad?

While debugging where does it get stuck within InitSysCtrl() if you were to pause the program execution? Is it stuck within the while loop you provided?

Best,
Kevin

Hi Daniel,

Could you look at how you're configuring InitSysPll() within f28004x_sysctrl.c for me? Are you using the internal or external oscillator?

Assuming you're using the LaunchPad try configuring the the external oscillator with the below if not already:

    //
    // PLLSYSCLK = (XTAL_OSC) * (IMULT + FMULT) / (PLLSYSCLKDIV)
    //
    InitSysPll(XTAL_OSC,IMULT_10,FMULT_0,PLLCLK_BY_2);

Best,

Kevin

Hi Kevin,

Many thanks for your suggestion.

It works now.
