TDA4AL-Q1: how to set QoS for C7

Hi Xingyu,

Could you clarify the functionality that the customer is looking for here with C7x?

Best,

Asha

Also why do you want to setup QoS for C7x?

Hi all:

          We have adjusted the qos before and solved the interference problem between the A core and other cores. The previous problem was that the functions of mcu10, mcu20, and mcu21 were fine, but after the A core started functioning, the functions of these cores were a bit abnormal, such as cycle instability and other problems. Now we have encountered a similar problem and found that there is no qos-related configuration in the default code of the c7x core, so I would like to ask how to configure the qos of c7x and use different channels from the default A core to achieve load balancing.

Hi Richard & Brijesh,

May I know if there is any update? Thanks

Hello,

What is the nature of the issue you are seeing?  Is there a particular path and endpoint which is causing issues?

One maybe first and easy knob to try is adjustments to the L2CC (UMC ECR/REGID 0X281).   This can assign a priority to transactions for a given C7 instance.  Register details are in the C7 Corepac SPRUIQ3 TRM.
