Native io-pkt Ethernet Driver(mpc85xx)

Hi,

I need some help to debug one of the issue we are facing in native io-pkt Ethernet driver (mpc85xx), it looks that after
 few packet transfer the Ethernet driver continue to hit the following error during packet receive with  following error
 "mpc85xx_receive(): status RXBD_ERR 0x1D04".

Following is the below code in receive.c where this error is logged.

// any problems with this rxd packet?
        if (status & RXBD_ERR) {
			// give old packet back to nic
            mpc85xx_add_pkt(mpc85xx, rpkt, this_idx);  
			log(LOG_ERR, "%s(): status RXBD_ERR 0x%X", __FUNCTION__, status);
			ifp->if_ierrors++;
            continue;
        }

It will be great if somebody can asset in analyzing/resolving following issue.

Thanx and regards,
Tarun

RE: Native io-pkt Ethernet Driver(mpc85xx)

Hi Tarun,

Can you specify following:

Command line to start io-pkt
Packet rate at which you are feeding packets. Also what kind of packets?
BSP detail  
SMP or single CPU core 
nicinfo results
 
At the moment it looks like Rx CRC errors in received broadcast frames.

BR,
Akash Goswami

Re: RE: Native io-pkt Ethernet Driver(mpc85xx)

Thanks Akash for reply. Is there any way to to know the cause and prevent this error.

Here is the below information.

Command line to start io-pkt: The below command is used in preinit script to start devnp-mpc85xx.so($ETHDRIVER)
mount -T io-pkt -o "mac=$MACADDR,deviceindex=3" $ETHDRIVER
mount -T io-pkt -o "mac=$MACADDR,deviceindex=2" $ETHDRIVER
mount -T io-pkt -o "mac=$MACADDR,speed=1000,duplex=1,deviceindex=1" $ETHDRIVER
mount -T io-pkt -o "mac=$MACADDR,speed=100,duplex=1,deviceindex=0"  $ETHDRIVER
echo "Enabling Support for QNet"
#mount -T io-pkt /lib/dll/lsm-qnet.so
mount -T io-pkt -o "bind=tsec3,no_slog=1" /lib/dll/lsm-qnet.so
echo "Enabling TIPC"
mount -T io-pkt -o "verbose=0,bufsize=131072" /lib/dll/lsm-tipc.so
echo "bringing up necessary interfaces"
/sbin/ifconfig tsec0 up
/sbin/ifconfig tsec1 up
/sbin/ifconfig tsec2 media 1000T mediaopt fdx
/sbin/ifconfig tsec2 up
/sbin/ifconfig tsec3 media 100baseTX-FDX
/sbin/ifconfig tsec3 up
/sbin/ifconfig tsec0 $IPADDR netmask $NETMASK up
echo "ifconfig tsec0 $IPADDR netmask $NETMASK up"

Packet rate at which you are feeding packets. Also what kind of packets?: Close to 1G on tsec2, packets are intermix of 
Multicast and Unicast packets. 

BSP detail:  QNX BSP for MPC8572, kernel is “procnto-booke-smp-instr”.

Re: RE: Native io-pkt Ethernet Driver(mpc85xx)

Hi,

Following is a similar post where Andrew has explained possible root cause of a CRC error:
http://community.qnx.com/sf/go/topc8829

Its hard to say the root cause of CRC errors, but try to isolate the problem using different cable type/ packet 
throughput rate/ packet length etc.  See if you can insert a gigabit switch between the board and testing machine, if 
this is a PHY related issue.
I havent seen this board, so cant comment more about it.

RE: RE: Native io-pkt Ethernet Driver(mpc85xx)

 
Hi Tarun,

Can you check whether the Linux also displays CRC error like this with
the same load condition ?
Linux image should have been preloaded into the flash.

Also one of the idea would be to check the device errata supplied with
the board documentation, if this behaviour is also captured there.

Akash Goswami
