I might be wrong but I THINK that open-drain settings are missing here. I note in the i2c example - they set the outputs as open drain like this..

//Set SCK as open drain
GPIO_REG_WRITE(
    GPIO_PIN_ADDR(GPIO_ID_PIN(I2C_SCK_PIN)), 
    GPIO_REG_READ(GPIO_PIN_ADDR(GPIO_ID_PIN(I2C_SCK_PIN))) | 
    GPIO_PIN_PAD_DRIVER_SET(GPIO_PAD_DRIVER_ENABLE)
);
