Hi liyang,

Hi liyang,

You can change the state of the GPIO pins as soon as the periph_init executes before that the rom bootloader controls the state of the pins.Please check the following post.

Thanks liyang.

Hi liyang,

Hi liyang,

According to the datasheet and the default state of the the GPIO's is input pull-down, there is no way to change the default state of the pins.

Thanks MT_dialog
