<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I am trying to bring up MCC (Multi Channel Communication controller) on MPC8270 board for T1/E1.</DIV>
<DIV>The overall configuration looks fine since I am able to have a communication properly if I do a T1 Cross over Loopback and tx/rx HDLC data.</DIV>
<DIV>The things do not work smoothly if I connect my T1 line with an external device and start HDLC.</DIV>
<DIV>I am seeing 'NO' (Rx Non-Octet Alligned Frame) errors in my rx buffers. Sometimes I also see Rx abort errors.</DIV>
<DIV>I do not see this issue on the tx side i.e the external device does not report any of these when I tx HDLC data to it.</DIV>
<DIV> </DIV>
<DIV>Does anybody have any experience dealing with this ? </DIV>
<DIV> </DIV>
<DIV>As far as clocking and sync with TSA is concerned, I have just configured <FONT size=2>
<P>CMXSI2CR register with 0x00 ( I have only TDM2A driven by CLK1) and nothing else. </P>
<P>Do I need to do something more for clocking etc? Also I am doing this before SI initialisation.</P>
<P>I will also try doing it just after TDM init and see if it helps.</P>
<P>Please help.</P>
<P> </P>
<P>Thanks,</P>
