What does the console (serial) window say when you get these failures? If you are getting IP_MAX_UNITS failures, then you need to recompile vxworks with IP_MAX_UNITS set higher than 1 (it needs to be >= PETH_NUM_DEVS + 1). The NetApp init code registers the END driver(s) with the IP stack and be default VxWorks only allows one registration with the IP stack (which is consumed by the Intel NIC/driver). You can see an example of how I did this in the supplied BoardSupport/VxWorks/IXP1200EB/config.h, search for MVR, or IP_MAX_UNITS, and then follow this model to build your BSP (or if you are using the supplied BSP, just define MVR and recompile) if that is not the problem, I am at a loss. Perhaps it is a version mis-match? The driver was written for VxWorks 5.4 (if I remember correctly) maybe something changed in the END interface...? The default routes were #ifdef'd out for the MVR application because we were demonstrating a routing protocol (OSPF) rather than static routes. In addition, the route table manager changed its interface slightly to support the notion of virtual routers. If you want to add a route, simply use the rtm_mvr code. look in SA1_CoreLibs/rtm-mvr/, the VxWorks shell commands are available from rtm_console.cpp/rtm_console.h if you just want to call them "by hand", or add them into any init code you want. erik

Hi,
I still get the same error , even reducing the number of PETH devices: -> NetApp_GigInit

In addition , I'd like to know exactly where the route for port 18 should be inserted in the fixed routing table that is implemented in \Ixp1200\SA1_Corelibs\app1200\net_app.cpp, because there is a preprocessor directive that banned the insertion of a route in the place where other routes are added. An extracted portion of the code explains this:

Sorry, I missed the last part of your email. The PETH driver ASSUMES it gets packets from port 18, you don't need to instantiate that many drivers. Simply instantiate drivers for the ports you want to logically represent to VxWorks (e.g, just the first 4 10/100 ports). Then each driver will enqueue for the transmit port associated with its instance, all will receive from port 18 and demultiplexing will be done based on the ingress port number within the packet descriptor. Note, you should be loading the MVRRefdes microcode with this driver since it has modifications to the microcode that allow the core to properly enqueue on the outgoing (transmit) queues.

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.

Hi, In the compilation process of Vxworks , I've found several flags specified in the Makefile , defs files and rules files that needs to be declared first. These flags have null values and they cause the whole make process to stop abruptly. For example: partialImage.o: $(LDDEPS) $(PRJ_OBJS) $(EXTRA_MODULES) $(COMPONENT_LIBS) $(LIBS) $(PRJ_OBJS_FILE) - @ $(RM) $@ flags like the Tornado source directory are not defined. Whats the procedure for giving values to them? Regards, Servio "Johnson, Erik J" wrote:

Hi, How should i simulate the strong arm core? Which refernce design does the strong arm code corrospond to? i want to add some code both in the microcode and in the strong arm and then simulate it. Please tell me how to proceed and point to the relevant documents. thanks, Sachin Jain Graduate student, computer sciences Univ. of Texas - Austin Res: 3401, Red River Street, #201 Austin, Tx - 78705 Ph : (512)-4726443 (R)
