pay attention to descriptor format: a PETH driver is built with RFC1812 uses a newer descriptor format but the reference design use the
Hi, Thanks for replying. Unfortunately, I'm still getting the Bad descriptor problem. I've tried both removing and adding RFC1812 from build>settings>assembler>preprocessor definitions in the workbench and also in the Makefile of /opt/ixasdk/examples/peth and /opt/ixasdk/examples/rtm but to no effect. Does anyone know if the peth driver and rtm application in SDK 2.01 is suitable for the ENP-2505 (Bridalveil) board or do I have to make any changes to them? Thanks. Regards, P.K.

descriptor. You need to remove -DRFC1812 from the peth/Makefile to set the PETH to older descriptor format.

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.
