Nominal SJW needs to be inside the FDCAN Bit timing parameter tree

My mistake. Doesn't make sense to have the nominal SJW mixed with the data bit configuration. It should be inside the Bit timing parameter tree view along with the other nominal configurations.

Totally agree and it's confusing. I've already requested months ago (internal Ticket number 152901) to reorganize the FDCAN "Parameter settings" so all the timings need to be in the same item (Bit Timings Parameters) in this order:

Nominal Prescaler,
Nominal Time Quantum
Nominal Sync Jump Width
Nominal Time Seg1
Nominal Time Seg2
Nominal Time for one bit
Nominal Baud Rate
Data Prescaler
Data Time Quantum
Data Sync Jump Width
Data Time Seg1
Data Time Seg2
Data Time for one bit
Data Baud Rate

Hope these changes will be implemented in the next release of CubeMx.
