Hi,
We have tried to configure the new GPIO's by following below steps. But the configured GPIO is not controlled.
1. configured the GPIO in "am43xx_idkevm_pinmux_data.c" file (MLO)
2. Do the below configurations in "GPIO_evmAM572x_bord.c" & "main.c" files (Application)
File: GPIO_evmAM572x_bord.c
#define MOTOR_0_ENABLE (0x0518) //GPIO4_18
#define MOTOR_1_ENABLE (0x0519) //GPIO4_19
/* GPIO Driver board specific pin configuration structure */
GPIO_PinConfig gpioPinConfigs[] = {
/* Output pin : AM437X_IDK_LD_PIN */
MOTOR_0_ENABLE | GPIO_CFG_OUTPUT,
MOTOR_1_ENABLE | GPIO_CFG_OUTPUT,
AM437X_IDK_GPIO_LD_PIN | GPIO_CFG_OUTPUT
};
/* GPIO Driver call back functions */
GPIO_CallbackFxn gpioCallbackFunctions[] = {
NULL,
NULL,
NULL
};
/* GPIO Driver configuration structure */
GPIO_v1_Config GPIO_v1_config = {
gpioPinConfigs,
gpioCallbackFunctions,
sizeof(gpioPinConfigs) / sizeof(GPIO_PinConfig),
sizeof(gpioCallbackFunctions) / sizeof(GPIO_CallbackFxn),
0,
};

File:main.c
int main(){
GPIO_init();
GPIO_write(0, GPIO_PIN_VAL_HIGH);
AppDelay(500);
GPIO_write(0, GPIO_PIN_VAL_LOW);
AppDelay(500);
}

}
But the configured GPIO is not set High.
