STM32F756ZGTX CAN setup (missing pin setup?)

I'm trying to get CAN working with this micro and a prototype PCB. I managed to rewrite the created code from 1.0.2 CUBE and adjusted it to use the example provided in the STM32756G_EVAL\Examples\CAN\CAN_Networking.

The Init does not cause any errors during setup, I set break points and stepped through to verify, and I adjusted the main() to simply send a message.

I am not seeing anything coming from my TX pin and if I send a message on the CAN bus it results in the bus going heavy.

Am I missing something such as a nested vector that needs to be changed to modify the GPIO pins to their CAN alternates? The INIT calls out functions that adjust these pins but they really don't appear to be changing over.

Thank you,
