by 이문복 05 Feb '04

05 Feb '04

Hello~~^^ I was developed to sdk 3.1 in ixp2400. Um... I buy ixp2400/ixp2800 Programming on Amazon. MSF device is SPI4 in ixp2800 but ixp2400 is POS-PHY Level 3. What kind of difference ixp2800 and ixp2400? I hold only one of scratch ring for single PHY. Therefore, scatch ring size hold 1024. Right ? ... ... MSF_interrupt_status = 0x0000 0e00 May be, no rbuf element was free to accept mpacket. Please, solve me~~! Thanks in advance.

IXA University Program IXP425 Student Design Competition Announcement
by Schuetze, Joel D 03 Feb '04

03 Feb '04

Greetings, We are pleased to announce the Intel* IXA University Program IXP425 Student Design Competition. The Intel IXA University Program Student Design competition will allow undergraduate and graduate university students from U.S. Universities to present innovative work based on the Intel(r) IXA architecture, specifically the IXP425 network processor. We have a web-based application process available through the IXAEDU.com website and all entries will be reviewed by an Intel panel of experts. The best qualified selected entries will be awarded grants and IXP425 development kits for the proposed projects. After the selected projects have been completed and submitted for judging, the top two (2) projects will be selected to receive an award presented at the Fall 2004 Intel Developer Forum (IDF). Please note that this competition is available for students enrolled at US Universities only. For complete information please visit http://ixaedu.com/news/DesignCompetition.

Behavior of the RFIFO.
by Mohamed Kone 27 Jan '04

27 Jan '04

Good day to everyone, I am new to development on IXP1200 and I have a few questions about the RFIFO's behavior. How do we know/test that the RFIFO is full? When the RFIFO is full, what is the default behavior? Does the previous content get overwritten by incoming packets or nothing gets inside until the RFIFO has space? Is the default behavior customable? Thank you for your time. Mohamed Kone College of Computing @ Georgia Tech Email: lechefs(a)cc.gatech.edu

BTW, it reminds me that the Developer Workbench is able to execute Foreign Models, and Intel provides versions of its API running with the simulator. It should be possible to execute the C code running on the core as a model interfaced with the simulator. I've not tested it however.

You'll find on the web several ARM simulators. I don't know however there accuracy regarding StrongARM instruction set. SimIT-ARM http://www.ee.princeton.edu/~wqin/armsim.htm ARM simulator in GDB: http://www.gnu.org/software/gdb/gdb.html But, do you really need a simulator? As far as I know, the main advantage of having a general purpose processor like the ARM core on the IXP processor is to be able to program with usual development tools (C, etc.). Why don't you program on x86 and then cross-compile towards your IXP1200 ARM target?

Have you loaded this kernel module? On the IXP2400, one should do "insmod MeDrv.o" before starting WBSrvr.

Hello, i would like to use the "Debug on HW" feature of the Workbench. I'm running the the Workbench Backend on the Target. If i try to download some code i get the following error at the target. # ./WBSrvr Rs_udbg_server RPC Task started Rs_udbg_server TCP created Rs_udbg_server entering svc_run enter rs_udbg_attachlib_1 - ClieDram Tmp Physical - Virtual - p_to_v = 0xdf4be00 ntName=121.110.43.16:1331, MeMasMeDrv: unknown ioctl code 0xc04c7814 k=f000f Target BIG ENDIAN MeDrv: MEDRV_SYSMEMSIZE ioctl failed, err = 5f leave rs_udbg_attachlib_1 - obj=9100 The message at the Workbenchside is the following: "Attach to debug library operation failed" I'm using an IXDP2800, the MontaVista Preview Kit 3.0 with an kernel2.4.21-rmk1-ds3 and the IXA-SDK3.1. Does anybody know this problem? TIA Frank

I think you are making an error. Intel libraries are implemented in _user_ space. The kernel module (MeDrv.o) is only used to make microengines CSR _visible_ to user space. > My question is, can i use the Resource Manager API's & Core Component > Library in user space, without loading them as modules > (perhaps building > these as libraries).

You need the module to access CSR spaces of microengines. Otherwise, all the library are in user space.

IXP2400 Intel libraries: kernel/user space
by romit dasgupta 14 Jan '04

14 Jan '04

Hello, I am working on IXP2400 and want to use the intel provided libraries for microcode loading/initialization and running. And in many occasions I want to access the Resource Manager APIs as well. I read the documents as provided by Intel , mainly the following Intel IXP2400/IXP2800 Network Processors XScale Support libraries Reference manual. I have not seen any explicit information in the above document which hints on running the resource manager & core compoent libraries in kernel space. Most of the examples that come with the ixa_sdk_3.1 however loads kernel modules which implements these libraries. My question is, can i use the Resource Manager API's & Core Component Library in user space, without loading them as modules (perhaps building these as libraries). I can acccess them in kernel space for sure but I have a feeling that it can be done through user space as well. Any insight on this will be highly valuable. Regards, -Romit
