we programmed both the ucc in hdlc mode(NMSI) . when both ucc are enabled simultaneously, one of the ucc stops working.please let us know any fix is necessary.  Development environment used is LTIB software.

 

I am getting CRC ERROR on UCC5(enabled first) and UCC7 is working fine.

 

hdlc0 Link encap:Point-to-Point Protocol
inet addr:10.0.0.1 P-t-P:10.0.0.2 Mask:255.255.255.0

hdlc1 Link encap:Point-to-Point Protocol
inet addr:20.0.0.1 P-t-P:20.0.0.2 Mask:255.255.255.0

TX packets:293 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:16

RX bytes:3504 (3.4 Kb) TX bytes:3504 (3.4 Kb)

 

Packets are dropped due to CRC error in BD's.

please suggest how to fix this.
