UMCC with more than 32 timeslots

xiluo · ‎09-01-2020

Hi All,

I am working on a platform based on QorIQ P1020. We use UMCC for channelized data. When configured for 32 timeslots (channels), everything works fine. However, when more than 32 timeslots is configured, none of the channels comes up. In my case, we have TDM input frequency of 8MHz (4 full E1). When I try, for example, 64 timeslots (including MU RAM routing, SI routing, channel extra parameter, channel specific parameters, etc), channels are not coming up.

I found that the channels are not up and running by looking at the channel specific parameters. The Tx/Rx states remain the same as configured value.

I would appreciate it very much if any one can provide insight to this problem.

Thanks in advance.

Hi r8070z, thanks for your response.

I think you meant P1020 does not support MCC through hardware. Yes, I am using UMCC through UCC. For 32 timeslots, I setup 32 SI RAM routing entries, 32 MU RAM routing entries, 32 channel extra parameters entries and 32 entries for channel specific parameters. In this case, everything works perfectly. However, if I change 32 to 64, none of the channels comes up. I can see the channels are not up by looking at the channel specific parameters. When channels run, the QUICC engine micro code will update the parameters. When channel don't run, there is no update. Please see the following for the memory/register dumps for the 64 timeslots case:

>I am working on a platform based on QorIQ P1020. We use UMCC for channelized data.
The P1020 does not support UMCC. There is no QUICC engine on the P1020.
I guess you run UMCC on device with UCCs. Please add more details how you change settings for the 64-channel case. Check the UCC Event register when UMCC hangs.
