After the GPIO115 of output mode is configured, it cannot be flipped ，and keeps 0，In the register view, Register value unchanged

I'm using an official routine and 180cCARD

GPIO_setMasterCore(115, GPIO_CORE_CPU1);
GPIO_setPinConfig(GPIO_115_GPIO115);
GPIO_setPadConfig(115, GPIO_PIN_TYPE_STD);
GPIO_setDirectionMode(115, GPIO_DIR_MODE_OUT);
DEVICE_DELAY_US(2000);
GPIO_writePin(115, 1);

while(1)
{
DEVICE_DELAY_US(1000000);
GPIO_togglePin(115);

What's the problem? thanks
