You also need to define PETH_NUM_DEVS=xx some integer value of the number of interfaces you want to install drivers for (e.g., PETH_NUM_DEVS=8). The vxworks_mvr.mak makefile compiles the driver into the NetApp code, if you want an example. erik

Hi, Does anyone has experience using Pseudo Ethernet drivers for StrongArm-Microengine communications? I got the following problem each time I compile with the -DPETH_DRV flag on (using Tornado Workbench):

-> ld < my_rtmmvr.out Loading C:/project2/ARMSA110gnu/rtmmvr.out | value = 3275480 = 0x31fad8 -> NetApp_GigInit

Data abort Exception address: 0x000cc294 Current Processor Status Register: 0x60000013 Task: 0x3bff74 "t31" value = 0 = 0x0

I am using -DPETH_NUM_DEVS=20, that is 20 PETH devices, because I want to use port No. 18 for the StrongArm-uengine communication.

Basically the problem is the invocation of the function: cookie = muxDevLoad(pethDrvNum, pethEndLoad, pethInitStr, 0, NULL); that can be found in \IXP1200\SA1_CoreLibs\app_1200\net_app.cpp

My goal is to transmit a packet from the StronArm to the uengine and viceversa. I think I should enable the PETH functionality first, but if anyone knows of another method for doing the same, please let me know ASAP.

Any help would be appreciated.
