DLP4710EVM-LC: Fail to set GPIO pin 5 to high

Part Number: DLP4710EVM-LC

Hello TI,

I modified Cypress SDK and tried to follow the procedures as described in some of threads of this forum (set GPIO 5 to 1 and wait for GPIO 6 to turn 1......).

However, when I set GPIO 5 to 1, I did not get GPIO 6 to turn 1. I then set GPIO 5 to 1 and read the value back, the value is still 0?? There is no error message shown.

          CY_HANDLE s_Handle;
 
          uint8_t Value=0;
    
          CySetGpioValue(s_Handle, 5, 1);
          if (rStatus != CY_SUCCESS) {
             printf ("CY:Error in setting GPIO 5 to 1 : Error NO:<%d> \n", rStatus);
          }

          printf("Succeed in setting GPIO 5 to 1 \n");

          CyGetGpioValue(s_Handle, 5, Value);
          printf ("GPIO value?:<%d> \n", Value);

Succeed in setting GPIO 5 to 1
GPIO value?:<0>

I also ported and built DLPC-API in my Linux PC, the procedures in DLP347x_dual_sample.c are are still the same (set GPIO 5=1, wait GPIO6=1, set GPIO9=1), but when I run the code, it's timeout, I think it is also wait for GPIO 6 to go high.

Can anyone give me a hand?

Thanks!
