TMS320F28388D: F2807 to F28388D Migration Issue

Hi,

Have you tried C2000Ware example to see if that works fine ? What hardware you are using ?

Regards,

Vivek Singh

I use TMS320C2000 microcontrollers development tools (dock and soc) with code composer 10.2.0 and C2000ware_3_04_00_00. All F2807 files in the project have been replaced with F28288 relative files. The project is compiled and linked correctly.

I have this code. Indicted "InitSysCtrl()" function is content in "F2838x_sysctrl.c" file.

static void MAIN_vInit(void)
{
InitSysCtrl();

InitGpio();

DINT;

InitPieCtrl();

IER = 0x0000;
IFR = 0x0000;

InitPieVectTable();

InitCpuTimers();

}

Hi,

What hardware you are using and what is the clock source ? Did you try any C2000Ware example from F2838x folder to see if that works ok ?

Hi Vivek,

I am working with the TMS320F28388D controlCARD (https://www.ti.com/lit/ug/spruil8b/spruil8b.pdf?ts=1632147238148&ref_url=https%253A%252F%252Fwww.google.com%252F).

I uploaded the code on the flash memory of CPU1 by means of  the on-board USB Debug Probe TI XDS100v2.

Software application crashes within the TI library function “InitSysCtrl()”.

Specifically, by means of the step by step debugger I verified that the code stalls on the execution of “PollX1Counter()” because  the “ClkCfgRegs.X1CNT.all” register counter is always to 0 (it never saturates).

Consequently, the application code remains locked forever within the following while-loop:

PollX1Counter(void)

{

    Uint16 loopCount = 0;

    //

    // Delay for 1 ms while the XTAL powers up

    //

    // 2000 loops, 5 cycles per loop + 9 cycles overhead = 10009 cycles

    //

    F28x_usDelay(2000);

    //

    // Clear and saturate X1CNT 4 times to guarantee operation

    //

    do

    {

       //

        // Keep clearing the counter until it is no longer saturated

        //

        while(ClkCfgRegs.X1CNT.all > 0x1FF)

        {

            ClkCfgRegs.X1CNT.bit.CLR = 1;

            ClkCfgRegs.X1CNT.bit.CLR = 0;

        }

        //

        // Wait for the X1 clock to saturate

        //

        while(ClkCfgRegs.X1CNT.all != 0x3FFU)

        {

            ;

        }

        //

        // Increment the counter

        //

        loopCount++;

    }while(loopCount < 4);

}

Although I am using the TI library function InitSysCtrl(), it seems that the 25 MHz external oscillator XTAL is always turned off. Why does it happen?

In order to verify if my electronic board is broken, I uploaded the code on a new TMS320F28388D control card but the result is the same.

As you suggested, I also executed the C2000 code example “device_support\f2838x\examples\cpu1\timer\timer_ex1_cputimers.c” without success. The problem still remains…

Waiting for a your feedback.

That is very strange. That is just a simple counter to count the free running clock. We have two version of controlCARD. Old version had 20MHz as default clock where is new one has 25MHz as default clock. Not sure which version you have but still there should be a clock hence it should not be stuck in that loop. There is a test point (TP6) to check that clock. Can you probe that to see if clock is running ? If not then I have to refer this to our hardware expert.

Vivek,

yesterday I have already verified in the test point, with my oscilloscope, that the clock is present and its frequency is exactly 25 MhZ.

I think your hardware experts need to be alerted.

We need to complete this migration from Piccolo to Delfino to make available our battery chargers and auxiliary services control and management software applications.

Ciao 

If clock is running then I don't see any reason why it should not work. I am assuming you are connected to CCS. Can you view this counter register in CCS Register view in continuous refresh mode and see if you see the value changing at all ? I am looping our SW team as well as HW team also provide their comment on this.

Did you try to look at the counter value in CCS register view as I requested in last post?
