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

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).

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).

Compiling armtoolchain
by Mohammad Shorfuzzaman 15 May '03

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. That's why I was not able to compile any c program. Has anyone done with that? Can you help me in this regard? Thanks, Mohammad Shorfuzzaman ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Hack to execute shared binaries on IXP2400
by David Mentre 15 May '03

15 May '03

Hello, I've finally found a hack to execute shared binaries on IXP2400 dev. platform with a home made gcc cross toolchain. You'll find it at below URL: http://www.linux-france.org/~dmentre/doc/en/ixp2400-exec-shared-binaries-hac k.txt By the way, this confirms that the cross gcc made with our howto can produce correct shared binaries. I 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
