IXP4XX datasheets/developers manual
by Vijay Lakamraju 09 May '03

09 May '03

Hi, I was wondering if anyone have access to the IXP4XX processor datasheets and the developers manual. I know this request might not be the most appropriate for this mailing list but just thot I would try. I have tried contacting the Intel tech support for this but it was in vain. Thanks for any help, Vijay -- Post-Doctoral Research Associate, Architecture & Real-time Systems (ARTS) Lab, 310 Knowles Engineering Bldg, University of Massachusetts, Amherst MA 01003 http://www.ecs.umass.edu/ece/realtime/ http://arts.ecs.umass.edu/~vlakamra/

Howto make the GCC big-endian toolchain for IXP2400/Linux (ARM XS cale core)
by David Mentre 07 May '03

07 May '03

Hello, You'll find below the build procedure we have used to make a gcc big endian cross toolchain for Intel IXP2400 which contains an ARM XScale core. I think this procedure is valid for any ARM target. We hope it will help others. Best regards, david --begin-- Howto make the GCC big endian toolchain for IXP2400/Linux (ARM XScale core) ===================================================================== Version 1.3 / 2003-05-07 David MENTRE <mentre(a)tcl.ite.mee.com> Mathieu BERTRAND <bertrand(a)tcl.ite.mee.com> -1. Last update With below procedure, the gcc is usable in -static but cannot produce dynamic linked programs. More exactly, the glibc-2.2.3 used in the ixp_ramdisk.gz should be replaced by glibc-2.2.5. 2.2.5 version has been patched to work with gcc3. 0. Used software - binutils-2.12.1.tar.gz - gcc-3.2.2.tar.gz - glibc-2.2.5.tar.gz - glibc-linuxthreads-2.2.5.tar.gz - gdb-5.3.tar.gz (Those packages can be found on ftp.gnu.org mirrors.) - sources of patched linux kernel for IXP2400. linux-2.4.19-rmk7-ds1 is working for us (YMMV) (Linux sources can be found at: http://www.kernel.org/pub/linux/kernel/v2.4/ Russel King patches can be found at: http://www.arm.linux.org.uk/developer/v2.4/ Deepak Saxena patches can be found at: ftp://source.mvista.com/pub/ds-patches/2.4 ) 1.

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...

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
