CubeMx issue: fixed FDCAN Tx buffer allocation = 32

Split from this thread.

Yes, but No!
CubeMX V6.16 now allows only exactly 32 TX Buffers ((TX Buffer Nbr + TX Fifo Queue Elmts Nbr) == 32).
But less then 32 TX Buffer is allows by the Hardware, and some times, required if You want to maximize the RX Buffers.

Hello @MHoll.2 

The CubeMX should allow (TX Buffers Nbr + TX FIFO Queue Elmts Nbr ≤ 32 ) instead of ((TX Buffer Nbr + TX Fifo Queue Elmts Nbr) == 32

A ticket (ID: 222211) has been escalated to the development team to address and correct this behavior.
