We are using Embedded Linux tools and Peth from Viosoft Corp. We have no problems running PETH and applications utilising the PETH. If you would like more information, you could contact Viosoft or their distributors. 1. Did you start your microengine? 2. If yes, check status, usually it is fault in microengine. Let me know if you need further information. -----Original Message----- From: owner-ixp1200@CS.Princeton.EDU [mailto:owner-ixp1200@CS.Princeton.EDU] On Behalf Of huangtao Sent: Saturday, February 15, 2003 11:34 AM To: ixp1200@CS.Princeton.EDU Subject: [ixp1200] peth driver question, need help I use peth driver with ixp1200, and meet this error message. this error will drop some output packet occasionally, who will tell me what is happend, thanks very much this error is below: $ insmod ue.o $ insmod octmac.o $ insmod giga_drv.o $ rs_udebug $ load $ ping 1.2.1.1 then I meet the error message like that: peth_start_xmit called peth_start_xmit: new descriptor = 0 Bad descriptor 0, dropping outgoing packet pethFreeDescriptor: descriptor = 0 pethFreeDescriptor: Bad descriptor 0 Best Regard
