TMDSIDK437X: Debugging FOC with FOC_GPIO_PIN0

Hi,

I don't think AM437x has a pin called FOC_GPIO_PIN0. Where do you find the information of this pin?

here is the part of file foc.c


/*
 *  ======== PWM ISR Hwi (10Khz) =======
 *  Continue FOC Routine.    Post the Semaphore so SPI read can start
 */
void PwmISR(UArg a0)
{
#ifdef ENABLE_DEBUG_FOC_PROFILE_GPIO
    GPIO_write(FOC_GPIO_PIN0, 1);
#endif

    Drv_PWM_ClearInt(pruIcssHandle);        // clear the INT in PWM module
    //Swi_post(swi0_foc_loop);            // post SWI to start FOC loop
    FocLoop();

#ifdef ENABLE_DEBUG_FOC_PROFILE_GPIO
    GPIO_write(FOC_GPIO_PIN0, 0);
#endif
}

herer is the part of foc_pwm.h

#define FOC_GPIO_PIN0 (0 + ETHERCAT_GPIO_OFFSET)

Hi Peter,

Please provide the full path of these two files. What software package is this?

Hi Bin Liu,

i created the motor_control_AM437x_arm from the pdk_am437x_1_0_17

here is the path to foc.c

here is the path for foc_pwm.h

Hi Peter,

Thanks for the details. I am assigning your query to the expert. The response will be posted here.

Hi Peter,

Pls probe GPMC_AD15 -> eQEP2_Strobe (U11-21).
