STM32H723VGT6 FDCAN 0x20 error on trasmission

Hi 

I am trying to send some CAN-bus messages from a STM32H723VGT6 mounted on a BIGTREETECH SKR 3 EZ V1.0

I am following this video to send standard CAN messages in external loopback mode (https://www.youtube.com/watch?v=kXyzaaSk6Qs&t=568s&ab_channel=ControllersTech). But whenever I reach the point where I add a message to the TxFifo I get the error 0x20 -> "Parameters error" but I am not sure what could be causing this

Here are the parameters I set for FDCAN1

To avoid additional variables we used the internal clock of the microprocessor, here is the final frequency of the FDcan peripheral

And the transreceiver mounted on the board is the mcp2542fd-e/sn
