fdcan communication between nucleo and discovery kit

[revvathi]

the objective of this particular project was to transmit data frames from stm32h750dbk(discovery kit) to stm32g491re(nucleo)
it is debugging and creating live expression for both of the data types in receiving and transmit end of board i have not connected any transceiver between them because it has inbuilt fdcan ports 
i am attaching both the codes for g4 and h7 
the picture of hardware and the live expression result when debugged separately

Ok, then you need to set your Nominal bitrate to that value ..

If you are not familiar with CAN/CANFD please study it before going ahead with tests.

i have matched it to 500000  baudrate at both the ends how do i proceed further like my hardware setup is ready data is ready to be transmited at h7 live expressions and data types have been intialised too on the other end but it still aint getting trasmitted i have gone through entire process of fdcan could u pls help me out
