HI I am working on TCI6614.And I want to design an LTE application.
Now I have some question about the AIF register.
My design scenario is 4X rate ,20M Hz and CPRI protocol. And the data path is Internal loopback.
All procedures are test in EVM board.
1. How to set up the Ingress AxC offset and Egress AxC offset ?
below is my code.
PeCommonSetup.PeAxcOffset[0] = aifLinkCfg[linkIndex].PeEvent2Offset + 32*n;
PeCommonSetup.PeAxcOffset[1] = aifLinkCfg[linkIndex].PeEvent2Offset + 32*n;
PdCommonSetup.AxCOffset[0] = n;
PdCommonSetup.AxCOffset[1] = n;
If n equal 0 or 1, the RX data is right. If n is greater than 1, the RX data is wrong.
I want to know where is wrong?
2. Another question is about connecting AIF2 with FFTC.
When sending data, the packet should only be pushed into TX queue just one symbol ahead the frame boundary.
So when connecting AIF2 with FFTC, how to ensure the transmission time is correct?
thank you very much!
