STM32CubeIDE - STM32U5 Port G Issue

George747
Associate

Using STM32CubeIDE Version 1.14.1
MCU Package STM32U5 1.4.0
Using custom  STM32U5A9ZJT6Q  PCB

Issue:-
a.) if (HAL_GPIO_ReadPin(GPIOG, GPIO_PIN_7)) // PG7 pin 92 is always reading 0
b.) HAL_GPIO_TogglePin(GPIOG, GPIO_PIN_12); // is not toggling the pin

Ports A, C & E are working as expected.
----------------------------------------------------------------------------------------------------------------

I found possible issue and fixes in Zephyr rtos:-
Zephyrproject-rtos / zephyr :- Drivers: gpio: stm32u5 portG not working #50158
[backport v3.1-branch] drivers: gpio: stm32: Apply GPIOG specific code to U5 series #50484

Question:
Has the STM32U5 Port G issue been fixed on the STM32CubeIDE?
If yes - how do I implement it?

Please advise.

Thanks SofT_it,

Adding:-

__HAL_RCC_PWR_CLK_ENABLE();
HAL_PWREx_EnableVddIO2();

 

worked for me.
