TIM15 in Slave Mode, Gated Mode to count the time a signal is High

Hi, 

 

I want to count the time that an incoming level signal is high for. 

To achieve this I setup Timer 15 as a Gated Mode Slave, which has it's counter counting while the trigger input is high. The trigger input is the Filtered Timer 15 Channel 1. For some reason when I connect my signal to my input Timer. Nothing Happens. The signal on the IO Pin TIM 15 CH1  is a 2V square Wave.

My own software seems correct. I then moved to Hal to see if I can achieve it.  

I've tried to use HAL to achieve this without any luck here is my HAL software.

Uploaded is the main and IOC file

I am working on the STM32G071

Thanks
