UMCC with more than 32 timeslots

307 Views
Contributor I

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.

Hi r8070z, thanks for your response.

I think you mean 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:

Thanks for replying to my question. I think what you mean is that P1020 does not support MCC by hardware. Yes, I am running UMCC through UCC, more specifically UCC1.

When I use 32 channels, I only setup 32 SI RAM entries, 32 MU RAM routing entries, 32 channel extra parameter entries and 32 channel specific parameters entries. In this case, everything works perfectly.

If I just change 32 to 64, none of the channels really starts. I can see that from the channel specific parameters. If a channel comes up, the QUICC engine micro code will load the parameters with new values instead of the configured values. As for the UCCE, the value is always zero when no channel is running.

The following are the memory/register dumps regarding the configurations.

> I think you mean P1020 does not support MCC through hardware.

I wrote that P1020 does not support UMCC, because it does not have QUICC Engine (i.e. there is not any UCC). May be I am wrong but I had checked 2 manuals: P1020 QorIQ Integrated Processor Reference Manual, Rev. 6 (does not mention the QE at all) and QUICC Engine Block Reference Manual with Protocol Interworking, Rev. 9 (does not mention the P1020 in the UMCC chapter). Here P1020/P1011 block diagram from the P1020 nxp page

There is not the QE. Please let me know document which says that the P1020 has UCC and supports UMCC.

Maybe you are right. I was told that the processor is P1020. However, the documentation I use is for P1021. I thought they are similar products with minor differences. Sorry about the confusions I made.

Please treat my questions in the context of P1021.

Thanks

I have not found any erratum or problem report which limits UMCC on the P1012/P1021 to 32 channels. I believe it can support 64 channels.

>if I change 32 to 64
I do not see in your answer what you have changed really. According to the UCC memory structure 32-channels case can be subset of 64 channels case. You already have working 32-channels case. Let make global parameters pointers and memory structure set as for 64-channels and only the LST bits in the SI Routing Entries and MU RAM Routing Entries are set for the 32-channels. Did you try to check 32-channels in this way?

I prefer look for some test case against dump checking by eyes. Because I can easily make mistake in the dump like that. By the way, may be I wrong but rows

do not look just initiated. Does it mean that the UMCC transmitted 40 channels, received 39 and hang?
