STM32F4 GPIO clock

Hello

I have an STM32F429 discovery board

I program it with : STM32-Matlab/target (embedded target for Matlab and Simulink), STM32CubMx (configuration tool) and the toolchain: Keil uVision5 (lite).

I tray a very simple Simulink program, which consist of blinking a LED (PG13, green LED).

For this purpose, I used a ramp generator, from simulink sources, (period 1s, 5% ramle ratio).

The output of the generator is connected to the GPIO_Write block (pin PG13)

The GPIO pin 13 configuration is set as :

GPIO_Mode: OUT

GPIO_Speed : Low

type: pull up

when I download the code in the board, the LED is fired but it doesn't blink

what can I do to resolve this problem ?

thank you for your help

best regards
