ZCU102 CCI-400 setting qosoverride to enable QoS

Hey,

 

I have a problem setting up the QoS of the CCI-400. I'm trying to set the qosoverride bit for the S3 of the CCI-400 (see lpd_cci (LPD_SLCR) Register) but I'm running into the problem that my settings aren't applied.

In the Register Description it says "This register may be written to only when FPD Interconnect is in reset." but when is the FPD Interconnect in reset and how can I force it to reset?

My idea was to set it in the Xilinx FSBL before init_peripheral(), where most of the FPD is taken out of reset but that didn't work either.

Is there any other way of doing this?

 

Note: I'm using the Engineering Sample 1 (ES1)

 

 

Kind Regards

Raymond Walter
