FDCAN not working on STM32H503CBT6

Hi, 

I'm trying to communicate two microcontrollers (STM32H503CBT6 and a NUCLEO-H503RB) via FDCAN but the STM32H503CBT6 is not sending any messages.

Both have the same configuration, but the NUCLEO-H503RB can send (I have checked it with an oscilloscope).

Searching for an answer I found this question on the forum, saying that the STM32U5F7 has the FDCAN disabled by hardware and I wonder if this is the case with the STM32H503CBT6 

Question: https://community.st.com/t5/stm32-mcus-products/fdcan-not-working-with-stm32u5f7/td-p/720224

Thanks!
