DCU bus priorization

Hello,

Is there a possibility to increase the priority of the DCU on the bus ? Or is there a mechanism like QoS (quality of service) ?

Thank you

Holger

Hi,

DCU has fixed priority level on the bus ("hard-wired" in the manual).

Which part are you using? MPC5606S or MPC5645S?

Hello,

I'm using Vybrid PVF65xxx.

After looking at the right place in documentation, I see that QoS is implemented in NIC301 and it has predefined values where DCU has level 14. So it looks like DCU has already highest priority on the bus.
