TDA4VL-Q1: J721S2 GPIO interrupt callback

ying-ren Chen
Prodigy 10 points
Part Number: TDA4VL-Q1

Tool/software:

Hi Expers.

I'm trying to use WKUP_GPIO0_34 pin on MCU2_0 for interrupt callback.

I start from the PDK gpio led_blank sample.

Adding GPIO_CFG_IN_INT_BOTH_EDGES flag in gpioPinConfigs[].

The GPIO_Read(0) can return the high/low level change and GPIO_enableInt(0) is called,

but my callback function is executed.

Is there any sample code and document that I can reference?

    Hi,

    Can you clarify what the issue is?

    There is an interrupt and callback called when your read a GPIO pin?
    Thanks,

    My main goal is to make the interrupt working at falling edge.

    Hi,

    Were you able to run the GPIO Led Blink example?

    Instead of manipulating gpioPinConfigs[] with GPIO_CFG_IN_INT_BOTH_EDGES, use GPIO_CFG_IN_INT_FALLING instead to configure interrupt only on falling edge of clock.

    Thanks,

    Neehar

    yes, i can run LedBlank example. the GPIO is blanking, but the AppGpioCallbackFxn() was not been triggered.

    TI__Mastermind 19880 points

    Hi,

    If the callback function is not triggered, then the test is not passing correct? And the blink iterations are not printed on the UART console?

    Are you running the example on a custom board or TI EVM?

    Thanks,

    Neehar

    I am running on our custom board. The test was not stopped, Uart console keep printing "Blink Iteration - 0 / 0".

    Im sorry. the "Blink Iteration - 0 / 0" is my modification. the 0 / 0 represent "gpio_intr_triggered" and "last_gpio_intr_count"

  • 0 in reply to ying-ren Chen
    TI__Mastermind 19880 points

    Hi,

    Have you made any other modifications? If "gpio_intr_triggered" and "last_gpio_intr_count" are equal, the test should not pass and the blink iterations should not be printed on the UART console.
    Thanks,

    Neehar

    The test did not pass. It stock in a infinite loop.

    and I change GPIO_board.h:

    213: #define GPIO_LED0_PIN_NUM        34 /*BOARD_USER_LED1*/ /* Pin 6 */

    Hi,

    Can you check the INTSTAT register to see if the interrupt is triggered?

    Thanks,

    Neehar

  • 0 in reply to Neehar Sawant
    Prodigy 10 points

    Which register should I looking at?

    I print out all GPIO_INTSTAT registers.

    UART_printf("\n Blink Iteration - %d / %d\n", gpio_intr_triggered,last_gpio_intr_count);
    UART_printf("INTSTAT34 %X\n", HW_RD_REG32( 0x42110034U ));
    UART_printf("INTSTAT5C %X\n", HW_RD_REG32( 0x4211005CU ));
    UART_printf("INTSTAT84 %X\n", HW_RD_REG32( 0x42110084U ));
    UART_printf("INTSTATAC %X\n", HW_RD_REG32( 0x421100ACU ));
    UART_printf("INTSTATD4 %X\n", HW_RD_REG32( 0x421100D4U ));

    this is the output:
    Blink Iteration - 0 / 0

    INTSTAT34 0

    INTSTAT5C 4

    INTSTAT84 0

    INTSTATAC 0

    INTSTATD4 0

    Hi,
    Each INTSTAT register will incorporate the interrupt status for two banks. Since you are using pin 34, it will be bank 3 bit 3 which is set to one showing the interrupt has occurred for that bank.

    Can you also confirm that SET_FAL_TRIG register bit is set as you want interrupt for falling edge?
    Thanks,

    Hello, similarly this sample doesn't work for me on the EVM board as it is in the SDK. The pad being configured is has GPIO0_5, not 11. There is also no PADCONFIG for the WKUP_PIN. However, when I disable the WKUP_PIN calls and changed the pin number from 11 to 50,  I still wait on the callback with no change.

    Do the SET_FAL_TRIG  register values include these changes made to the gpioPinConfigs[]?

    Thanks,

    I had set gpioPinConfigs[] to GPIO_CFG_IN_INT_FALLING.

    I write 0xFF to INTSTAT5C(0x4211005C). The INTSTAT5C can be clear, and trigger again.

    Hi,

    Can you provide the output console logs and INTSTAT registers if you revert the changes made to GPIO_board.h? As in using the original GPIO_board.h file even if the physical LED will not blink.
    Thanks,

    Hi,

    I just notice that the trigger type was set to GPIO_CFG_IN_INT_RISING.

    set to GPIO_CFG_IN_INT_FALLING, the SET_FAL value was 4.

    this is the uart log.

    Hi,

    The interrupt is getting triggered as INTSTAT23 is updated every time but the callback function is still not getting called.

    Can you revert to the original GPIO pinNum in GPIO_board.h and send the logs again?
    Thanks,

    Neehar

    Hi, sorry for the late reply.

    I use the original GPIO_board.h. and keep the custom main_led_blink.c.

    It keep showing

    IntConfig:  portNum[0], pinNum[34], bankNum[2], intNum[0], eventId[0]

    about every 2 second.

    Hi,

    ying-ren Chen said:

    This seems to be due to a boot issue as the logs did not show repeats before correct?
    Have you made any further changes to SBL or your application?
    Thanks,

    We made some changes for our DDR in /ti/board/.

    I think I'll get our evm board and try again.

    Hi,

    When are you printing the INTSTAT register? It may be cleared before you are printing. I suggest printing either inside or before the callback function.

    Can you provide the pinmux setup for the new pin you are using?

    I put the read INTSTAT inside the callback function. It's still 0.

    Note. the GPIO_LED0_PIN_NUM was set to BOARD_USER_LED1/* Pin 6 */

    Can you provide the pinmux setup for the new pin you are using?

    I didn't change anything except GPIO_LED0_PIN_NUM 34 in GPIO_board.h.

    all setup was restore to original PDK.(ti-processor-sdk-rtos-j721s2-evm-08_06_01_03)

    Hi,

    ying-ren Chen said:

    I put the read INTSTAT inside the callback function. It's still 0.

    Can you try to step through the code in CCS? You will be able to see the INTSTAT01 variable updated when there is an interrupt for pinNum6.

    ying-ren Chen said:

    I didn't change anything except GPIO_LED0_PIN_NUM 34 in GPIO_board.h.

    The pinmux will not be set up for WKUP_GPIO0_34 as it is not actively used on the EVM. The current ball D21 is set for MCU_OSPI1_D0 and therefore you will not be able to do any GPIO manipulations for pinNum 34. You will have to remove MCU_OSPI1_D0, assuming it not used by your application, and add the pinmux for GPIO by setting the pin mode to 7.

    You can see the full pinmux at the following path: [PDK_INSTALL_PATH]/board/src/j721s2_evm/J721S2_pinmux_data.c

    Thanks,

    Neehar
