Error in executing 'step' command in HAL_GPIO_Init

Hi Community,

I am working on a stepper motor driver development board that uses SPI for configuration and a few GPIOs for control. The development board uses a 5V logic level and needs an interface to STM32G491RE. By referring to the datasheet I choose the following pins which are 5V tolerant (denoted by FT) for SPI (PC10, PC11, PC12, PA15) and GPIO (PA13, PA14).

When I run a debug session I can see it crashes at HAL_GPIO_Init at the following line.

With a message on the console as below

What might be wrong?

STM32CubeIDE: 1.13.1

HAL : FW_G4 V1.5.1
