PC18 and PC19 not working as normal IOs

[thor171]

Hi,

I want to use PC18 and PC19 on a CH32x035 as normal IOs, but it seems as the debugging interface is still running on those pins. I can't control their behaviour.
This is the initialization, am I missing something?

`int main(void)
{
SystemInit();

funGpioInitAll();
//  GPIO C18 and C19 Push-Pull

GPIO_port_enable(GPIO_port_C);
GPIO_pinMode(GPIOv_from_PORT_PIN(GPIO_port_C, 18), GPIO_pinMode_O_pushPull, GPIO_Speed_10MHz);
GPIO_pinMode(GPIOv_from_PORT_PIN(GPIO_port_C, 19), GPIO_pinMode_O_pushPull, GPIO_Speed_10MHz);
GPIO_digitalWrite(GPIOv_from_PORT_PIN(GPIO_port_C, 18), low);
GPIO_digitalWrite(GPIOv_from_PORT_PIN(GPIO_port_C, 19), low);

}`
