I had sought help a while back for code on establish FDCAN communication in Classic mode between H7A3ZI-Q and G474RE, I did get the correct code and it indeed worked with the two boards, but now when I try to run it on Normal mode, the code fails to recieve data on the other end. It would be really helpful if someone explains how to do so. Please find attached zip files containg the code for FDCAN communication in Classic Mode.

Hello and sorry for the late answer.
I didn't understand the case.
You said the following:

The code worked on the two boards. What do you mean by that? in Loopback mode?
Check if you are using the correct FDCAN Tx/Rx pins connected to the transceivers i.e. the same as the ones configured in the CubeMx.
For the pin config use HIGH or VERY_HIGH for pin speed.
