IXP2400/Linux routing sample
by Mirko Benz 26 May '03

26 May '03

Hello, We are using an IXDP2400 with a Gigabit module. So far we managed to set up a cross compiler, get Linux running and explored small sample programs on the hardware. Unfortunately the Linux support of the SDK is still incomplete. We are facing problems with the Linux Gigabit interface driver (does not find the board during boot up). On the other hand, the initialization part for the routing application is for VxWorks only... Has anyone managed to get the routing application running? Help/comments are very much appreciated. Regards, Mirko

The FBI units cycle counter can be read from the microengines using the csr instruction.. I have used the instruction. The paper mentions "instrumenting the code to use the IXP1200 cycle counter" Is that what you mean by that, or are you doing anything else? -- Shyamal Pandya Arizona State University Addr: 920 S Terrace Rd #102 Tempe AZ 85281 Phone: 1-480-966-1982 >From: "Yitzchak M.

Question on setup ENP2505, urgent!
by feng 22 May '03

22 May '03

Hello, I got a ENP2505 board from my supervisor. He joined the intel IXA university program. But when I tried to setup this board according to the IXA Education Workstation Setup Guide, I always failed in Section 7. After I finished install software for ENP2505 and tried to boot the board using " ./bootixp " boot script, the board always entered a Cygmon environment and also I can not see the message "Finished ENP-2505 driver install" as mentioned in this guide. Then I tried to ping the board in another terminal window, it failed. I thought it's true. Because actually the Linux system do unknow the board currently. So, is there anybody know which options I should choose before I boot the enp2505 board. VxWorks, System Monitor or Cygnmon mode in this step? Do u know what's the problem? best, feng

Hack to boot Linux on IXP2400
by David Mentre 22 May '03

22 May '03

Hello, I have documented the hack that allows to boot Deepak Saxena Linux kernel on IXP2400 with an old RedBoot. As usual, you'll find in at: http://www.linux-france.org/~dmentre/doc/en/ As pointed out several times by Deepak, this is a *hack* that is not intended to work in the future. Hope it will help others, ;-) Best regards, d. -- David Mentré <mentre(a)tcl.ite.mee.com> - Research engineer Mitsubishi Electric ITE-TCL / European Telecommunication Research Laboratory Phone: +33 2 23 45 58 29 / Fax: +33 2 23 45 58 59 http://www.mitsubishi-electric-itce.fr

Open source network stack?
by Øyvind Hvamstad 21 May '03

21 May '03

Hi, I wonder if there is an open source implementation of a network stack, or a field stack for ENP-2505? I'm not quite sure what a field stack is, but someone told me that a network stack would probably be exceeding the cards resources. Any hint or help is welcome -- Øyvind Hvamstad

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

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

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

RE: [ixp1200] Compiling armtoolchain
by David Mentre 16 May '03

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).

You should give us the error messages from the command executed before make aborts the compilation. As a rule of thumb, always give the last command executed by make. Anyway, I would say that your compilation fails to produce documentation, probably because you don't have a needed package (info probably).
