Question on IXP1200 Giga port
by Wong Kim Sing 20 May '03

20 May '03

Hi, I would like to ask is anyone done any research or project on the IXP1200 Giga port to fast ethernet port communication? Recently, I got a project that required to aggregate traffic from fast ethernet port to giga port and via versa, but can't get it working. Please help if anyone has any ideal, thank you.

Re: [ixp1200] Question on setup ENP2505, urgen (fwd)
by Feng Tang 20 May '03

20 May '03

Hello, all Sorry to trouble you. But I do hope to solve my problem quickly, since I have waste much much time on it yet. I am using the ENP2505 board. When I tried to setup it, I met the problems. After I run the .ixstart, it inside invoked create_enivronment.rc and boot_bv before the system enter embedded linux by my thought. Here, create_environment.rc has no any problems, because it is very simple. But, when boot_bv finished running here, I got the below information which was recored in the boot_bv.log. " [root@cordelia bin]# cat boot_bv.log eth1: unknow interface: No such device rmmod: module pciDgNet is not loaded rmmod: module pciDg is not loaded insmod: a module named bv already exists (null): unable to open device '/dev/bv' encountered system error 2: No such file or directory rmmod: module bv is not loaded [root@cordelia bin]# " " [root@cordelia bin]# cat boot_bv ./unload_pciDg ./load_bv ./bvloadapp ./unload_bv [root@cordelia bin]# " I thought my boot_bv should run inproperly, otherwise the system won't stop until a message appear after the cygmon prompt. " cygmon> .ixstart global time out " Do you think the problem is I install the enp driver incorrectly or something else? But I thought I have re-install the whole system more than 20 times. It' impossible I always make the same mistakens here. By the way, do you think my PC's pci does not compatible with this enp board? best, feng

Request For Comments
by Øyvind Hvamstad 19 May '03

Hi, I am supposedly basing my thesis on the ENP-2505 board. I initially thought that I'd "enhance" the VERA, but that idea failed due to compatability problems. Now I have come up with something else. With the risk of exposing my idea for grabs (not that I don't trust you), I will roughly describe it here, and hopefully, some of you will comment on it. Well here goes. My Request For Comments: Abstract. I'm considering a "proxy-cache server" that in a possible multimedia context is "caching" blocks in a stream. Now I would like to offload some of this work to the IXP card by say, collecting packets that are to be cached, and send them collectively to the host, thus generating fewer interrupts. For this to be done some basic steps must be implemented: - Is this packet classified such that it may be considered for caching? - Is it to be cached? - When caching, collect the data untill a 4K block is gathered, then send it to the host over pci(possible bottleneck). I'm a rookie/newbee when it comes to programming the ENP-2505, so my question is how do I do this? I guess I need a network stack to strip the incomming packets. Has anyone implemented such a solution, say from mpacket -> UPD? Does this idea sound doable or is it ridiculous? Hope I didn't waste your time. Øyvind Hvamstad

Hello, > From: rasit(a)cs.umanitoba.ca [mailto:rasit@cs.umanitoba.ca] > As for the command *before* the failure, the whole package is build by > a single make, so we don't know unless we dissect the makefile. Usually, make prints on terminal all commands executed (gcc someting, cd'ing in some directory, ...). What I was saying is that we need at least the command producing the error to be able to tell what's going wrong. Otherwise, we can't help. ;-) Ok, looking more closely at what Mohammad had provided, the failing process seems to be the 'makeinfo' command (probably due to a syntax error or an old command no longer supported). As documentation is not useful for compiling programs, you should be able to comment the documentation target in the makefile in order to avoid that step (look for doc-something targets in the makefile).

Hi all, We are working to set up an IXP1200 Linux development environment. We got the cross compiler from http://www.netwinder.org/~urnaik/ixp1200_howto.html. and followed the steps as said in this website. We've done successfully the initial stages and able to talk to IXP1200 and also get Linux prompt by doing "gl". However, we are facing problems with compiling and installing armtoolchain. We used Linux Red Hat "9". I've downloaded the necessary tar files in the download directory and performed instruction as said in the README file. The completiion of "make" ends with these errors: makeinfo: Removing output file `/root/ixp1200_linux/src/glibc-2.1.3/manual/libc.info' due to errors; use --force to preserve. make[3]: *** [libc.info] Error 2 make[3]: Leaving directory `/root/ixp1200_linux/src/glibc-2.1.3/manual' make[2]: *** [manual/subdir_install] Error 2 make[2]: Leaving directory `/root/ixp1200_linux/src/glibc-2.1.3' make[1]: *** [install] Error 2 make[1]: Leaving directory `/root/ixp1200_linux/build/glibc-2.1.3' make: *** [glibc] Error 2 I've run "make" several times and got the same errors.

using addresses of labels
by Cyrus Hall 14 May '03

14 May '03

Hi there all- I'm currently trying to build a table of address to parts of a filter I've written. IE, you have a value, index into the table, and jump to the associated address in code. The jumping is simple enough, save the PC and replace it, give up control, and wait for the ctx switch back in. Not hyper efficient, but not bad when you're only filter one or two fields. Returning is simple enough as well. The problem I'm having is actually get the address of code. This clearly needs to be done at compile time (there doesn't appear to be a linker involved in loading code onto the ME's), and would seem to be as simple as replacing the symbolic label with it's final address. Yet, there seems to be no way to do something like: immed32[var, label#:] Has anyone done anything like this and\or know how? Thanks, Cyrus

Hi Vijay, maybe I can help you with more information.

But all that I had found earlier was a white paper on the IXP425. Well, what I am hoping to get from the datasheets are real power dissipation numbers. While the product brief just simply says "1.0 to 1.5 Watt typical", I was wondering what would be the dissipation if the XScale or the whole chip was clocked slower. Moreover, is there a way to clock gate or switch off any of the Ethernet NPEs? Any info on this would be helpful.

Looking for patches or fixes to have a working WBSrvr on Linux fo r IXP 2400
by David Mentre 07 May '03

07 May '03

Hello, We are currently having an Intel IXP2400 Development Platform. Using only free software available on the web, as well as Intel sources available on SDK CDs, we have been able to compile a complete cross tool chain (C only), compile and run the Linux Kernel (2.4.19-rmk7-ds1), and boot on Intel ramdisk. We have also successfully (cross-)built medrv.o and WBSrvr for linux with our tooolchain. While medrv.o seems to work correctly, we have issues with our home built WBSrvr: 1. we are unable to make a Pause in debugging. The WBSrvr binaries found on various Intel SDK exhibits the same behavior. Breakpoints and Restart are working correctly. Please find below two logs of WBSrvr with the [1]faulting Pause (notice err code res=9114) when manually called from workbench and [2]the working Pause using a breakpoint. 2. the WBSrvr segfaults if compiled from vanilla sources. Adding some debugging printf solve the issue, so there is probably a race condition in thread code of WBSrvr. Has anybody looked at those issues. Any idea how to fix them?

I got the mac addresses form enp> test macadd show....it displayed all 4 macs addresses.. in the ixsys*.config file i added these macadd to the ports 0, 1, 2, 3... ( i havent modified the route* file, like some had suggested to at the GW, show I? ) ... did ./ixstart ixsys*.config.... ifconfig .. for the l3 sample displays all 4 interfaces for the count sample displays none of th interfaces ? in both cases when i try pinging the port from another machine directly connected by a crossover, it says network unreachable... any ideas?? when i did a tcpdump on the external machine it hung and now refuses to reboot? can i connect the port to a LAN through a straight cable and be able to notice activity?? thanx, vikram ----- Original Message ----- From: vikram nayak <vnayak(a)usc.edu> Date: Thursday, April 17, 2003 8:52 pm Subject: Re: RE: [ixp1200] l3fwdr > > how do i prog the PHY device so that its 10MB mode is not default.

problem of enp2505 driver on dell optiplex gx260
by Yong Liu 02 May '03

02 May '03

Hi, When I load the driver for the enp-2505 card on the dell optiplex GX260, the driver cannot be loaded, and I see an error using dmesg command: bv: MEM 0xD0000000..0xDFFFFFFF 256M PCI mem base is 0xD0000000 PCI mem window size is 0xFFFFFFF Failed to map memory Anyone can run the enp card on the same PC? Btw, I use the kernel in the ixa-edu cd. Thanks Yong Liu

Hi, The IXP1200 hardware manual gives the memory map of the IXP1200. Can ioremap be used to map the physical addresses given into the linux kernel's address space ? Kamesh.

Hi again, I finally got the L3 appl running. I managed to force the eth. card on the Linux box to run at 100Mbps, and also i noticed that it takes two config files ixsys.config-l3 and ixsys.config. And ixsys.config, is the one that brings up the IXP interfaces. I'll be looking to modify the Count App thou' ... like i said ealier the interfaces are not listed when i do an ifconfig, also when I ping the card from an external box , ping returns nothing. But the count value on that port keeps incrementing.,, is this how it supposed to work? thanx, Vikram On Fri, 25 Apr 2003, Abhijeet Joglekar wrote: > Vikram, > > Sorry, couldnt get back earlier. > > I havent looked at it in detail, but I am guessing that the L3 > MicroAce does something special (like maybe adding device entries) > which the Count or Bridge MicroAce does not do.
