TDA4VM: How to implement GPIO interrupt function on TDA4VM?

Hi qidong liu,

I think you would have to change SoC Config and provide GPIO0 base address (GPIO_socGetInitCfg and GPIO_socSetInitCfg).. Then you also have to configure GPIO interrupt. 

I would suggest to refer to the PDK example in ti-processor-sdk-rtos-j721e-evm-08_02_00_05\pdk_jacinto_08_02_00_21\packages\ti\drv\gpio\test\led_blink\src\main_led_blink.c and make similar changes for GPIO0. 

I would also suggest search on the TI e2e forum, you could find many references for GPIO interrupt implementation.

Hello, the code above is based on ti-processor-sdk-rtos-j721e-evm-08_02_00_05\pdk_jacinto_08_02_00_21\packages\ti\drv\gpio\test\led_blink\src\main_led_blink.c and the information on the TI E2E forum written. But now my GPIO interrupt is still not working. Please help to confirm, what is wrong with my configuration above?

The code in ti-processor-sdk-rtos-j721e-evm-08_02_00_05\pdk_jacinto_08_02_00_21\packages\ti\drv\gpio\test\led_blink\src\main_led_blink.c, I see the feedback on the TI E2E forum is running on MCU1_0 . I now want to implement GPIO interrupts on mcu2_0 above the main domain. I don't understand the interrupt routing relationship in the middle. Do you have a more intuitive demo?

I think there are many missing points, like you are not changing GPIO0 base address using get/set Soc Config. Also you are not configuring interrupt. 

So please go through this example and call these missing APIs.

Hello, if I want to configure the interrupt function of GPIO0_99, how should I set the idx of GPIO_socGetInitCfg? During the configuration process, is the baseAddr in the GPIO_v0_HwAttrs structure corresponding to the idx of GPIO_socGetInitCfg? Taking GPIO0_99 as an example, how should the variables in GPIO_IntCfg be configured?

//Configure GPIO0_99(W23) as interrupt
typedef enum {
    ENUM_TEST_GPIO_INT_FUN_W23 = 0,
}GPIO_CTL;

GPIO_PinConfig gpioPinConfigs[] =
{
    GPIO_DEVICE_CONFIG(0, 99) | GPIO_CFG_IN_INT_BOTH_EDGES | GPIO_CFG_INPUT,
};

GPIO_CallbackFxn gpioCallbackFunctions[] =
{
    NULL,
};

GPIO_v0_Config GPIO_v0_config =
{
    gpioPinConfigs,
    gpioCallbackFunctions,
    sizeof(gpioPinConfigs) / sizeof(GPIO_PinConfig),
    sizeof(gpioCallbackFunctions) / sizeof(GPIO_CallbackFxn),
    0x8U
};

app_init()
{
	boardCfg = BOARD_INIT_PINMUX_CONFIG | BOARD_INIT_UART_STDIO | BOARD_INIT_MODULE_CLOCK;  
    Board_init(boardCfg);
	int pinNum = 99;
	int bankNum = pinNum/16；									//bankNum=99/16	Is this calculation correct?
    GPIO_v0_HwAttrs gpio_cfg;
    GPIO_socGetInitCfg(bankNum, &gpio_cfg);    					//The idx here uses the bankNum variable, is that correct?
    gpio_cfg.baseAddr = CSL_GPIO6_BASE;    						//How should the baseAddr be determined here?
	gpio_cfg.intCfg[pinNum].intNum = 256 + bankNum;				//How to determine the intNum here?
    gpio_cfg.intCfg[pinNum].intcMuxNum = INVALID_INTC_MUX_NUM;	//How to determine the intcMuxNum here?
    gpio_cfg.intCfg[pinNum].intcMuxInEvent = 0;					//How to determine the intcMuxInEvent here?
    gpio_cfg.intCfg[pinNum].intcMuxOutEvent = 0;				//How to determine the intcMuxOutEvent here?
	GPIO_socSetInitCfg(bankNum, &gpio_cfg);						//The idx here uses the bankNum variable, is that correct?
	GPIO_init();
    GPIO_setCallback(ENUM_TEST_GPIO_INT_FUN_W23, AppGpioCallbackFxn_W23);
    GPIO_enableInt(ENUM_TEST_GPIO_INT_FUN_W23);
}

This is my configuration code, please help to check where is the configuration problem? Regarding the determination of variable values in the code, please help to explain.

Hi qidong liu,

Any further update/questions on this ticket?
