Hi all, I was wondering if anyone could tell me how to get the ENP-2505 to forward packets by using the peth driver and hardware debugging on the workbench and not through the MicroACE framework. After inserting the ue.o, octmac.o, giga_drv.o modules and running rs_udebug and rtmapp, I started a hardware debug session using the L3fwd16 project. I then loaded the peth driver and initialised the peth devices similar to the example in the "load" file. However, when I try to ping a computer connected to the ENP-2505 ethernet port, I get this message: Bad descriptor 0, dropping outgoing packet pethFreeDescriptor: Bad descriptor 0 I've tried defining RFC1812 in the code and also in build>settings for the project but the same problem occurs. Any help or pointers would be greatly appreciated. Thanks. Regards, P.K. Chong Multimedia University, Malaysia
