TDA4AL-Q1: GPIO0_32 can not output high level

Hi,

Thanks for this information, I will look into this and get back to you tomorrow.

Hi TI,

     Please help me check, thank you very much.

Hi Daohong,

Did you complete the pinmux configuration for GPIO0_32? You can refer to the TI SysConfig tool to help with this.

Neehar

Hi,  Neehar,

      I do complete the pinmux configuration for GPIO0_32:

    pinmuxPerCfg_t gGpio0PinCfg[] =
    { 
         /* MyGPIO0 -> GPIO0_14 -> AB28 */
        {
            PIN_MCASP0_AXR4, PIN_MODE(7) | \
            ((PIN_PULL_DISABLE | PIN_INPUT_ENABLE) & (~PIN_PULL_DIRECTION))
        },       
        {PINMUX_END}
    };
    #define BOARD_SOC_DOMAIN_MAIN    (0)
    pinmuxModuleCfg_t gGpioPinCfg[] =
    {
        {0, TRUE, gGpio0PinCfg},
        {PINMUX_END}
    };
    pinmuxBoardCfg_t gJ721S2_MainPinmuxData[] =
    {
        {0, gGpioPinCfg},
        {PINMUX_END}
    };
    Board_pinmuxUpdate(gJ721S2_MainPinmuxData, BOARD_SOC_DOMAIN_MAIN);

    appInitGpio();
    
    

Dear Neehar ,   

     Please help me check, thank you very much.

Hi Daohong,

This pinmux configuration looks correct.

What do you define PIN_MCASP0_AXR4 as?

Do you have any problems with any of the other GPIOs?

Regards,

Neehar

Dear   Neehar ，

     Please help me check, thank you very much.

Hi Daohong,

Is there a reason you use port 1 for the get and set GPIO config?

Additionally, refer to this for any clarifications: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1126741/faq-tda4vm-using-pdk-gpio-driver.

Hi Daohong,

Following up, are there any updates on the issue?

Neehar

Hi Neehar,

Is there a reason you use port 1 for the get and set GPIO config?

->

the index here is 1, so the GPIO is wkup_GPIO0

the code path:vision_apps/utils/sensors/src/app_sensors.c

Please help me check,thank you very much.

Hi Neehar,

k3conf read 0x11c080, value is 0x50000.

Please help me check,thank you very much.

Hi Daohong,

Was this resolved?
