RZ/T2M MTU3 interrupt/callback configuration

Hi everybody,

I am new to Renesas world and I need some help.

I am using the Evaluation board RSK for RZ/T2M.

I am trying to develop a motor control application and I need an interrupt every PWM period. 

I started from the example of "Getting Started with RZ/T2M FSP for MTU3+POE3" (https://www.renesas.com/us/en/video/getting-started-rzt2m-fsp-mtu3poe3) and the 6 channels PWM work fine.

Now my problem:

I am trying to set up the interrupt with the FSP configuration and I really tried every method I found on the internet but nothing worked! 

I tried to define the callback and set the priority or tried to define directly the user interrupt but the interrupt was not triggered.

Here are some screenshots of my configuration. I hope you can help me.
