Austen, I believe that you are running the version of the diags with the Gigabit loopback bug.. v1.2.76. The first patch for this fix would have been in build v1.2D.77, as well as incorporated into v1.3.141 software. Please make sure you are compiling and flashing the latest diags and let us know if you are still having problems.

We at Tech are trying to debug some problems with our gigabit ports: they've seemed to stop working (sending and recv'ing) suddenly and there appears to be no reason for it.

We updated the diagnostics (b/c the old version has known gigabit problems) as per the release notes in SDK v1.3: we reinstalled the boot image boot1200.bin overwriting everything and installing Diagnostics v1.2.76. When we run the diagnostics, they fail on the gigabit tests; nothing is sent or received except in one case: if the first thing you do when you run the diagnostics is gigabit, internal loopback mode, run test continuously, then 16 packets are sent--after that nothing and if you go do something else (like an octal test or external loopback test) before you try this test, nothing happens. However, the octal tests work. Does anyone have any suggestions? Austen McDonald austen(a)cc.gatech.edu God does not care about our mathematical difficulties.

Hi Austen, I forwarded your question to the TME for the board we will see if we can find the answer. --Dirk > -----Original Message----- > From: Austen McDonald [mailto:austen@cc.gatech.edu] > Sent: Tuesday, September 18, 2001 9:49 AM > To: ixp1200(a)CS.Princeton.EDU > Subject: [ixp1200] Problems with Diagnostics... > > > > We at Tech are trying to debug some problems with our gigabit > ports: they've seemed to stop working (sending and recv'ing) > suddenly and > there appears to be no reason for it.

linux on ixps and memory map
by Josh Fryman 14 Sep '01

14 Sep '01

hi all, this is a follow-on to my earlier question. i got enough information to find a trivial way to change the amount of memory linux is using, but now i'm trying to do some more challenging things, and having no luck. first off, to change the amount of memory being used, the simplest way is to edit "arch/arm/kernel/setup.c" and change the "#define CONFIG_CMDLINE" to include "mem=XM", where X=4,6,8... i received many suggestions, but they all involved more work than this ;) [note: X = size of space for linux + size of ramdisk] second, by resizing the ramdisk image down to 6MB from 8MB, we were able to save another little bit of space. between these two options, we can comfortably run linux in a 14MB footprint... but that leaves now 18MB of free space. now what we want to do is to move this space used by linux and ramdisk to the top or bottom of memory, and increasing the SDRAM_PACKET_xxx values such that instead of the sdram uncached packet buffer area being 8MB, it's increased to 18MB. i've modified the various values in include/asm-arm/arch-ixp1200/ hardware.h ixp1200eb.h arch/arm/mm/ mm-ixp1200.c the various combinations i've tried: - make the buffer at the top of memory, size > 8MB - make the buffer at the bottom of memory, size > 8MB - make the buffer in the middle of memory, size > 8MB - make TWO buffers, at top and bottom, each size = 8MB no matter how i try to modify the behavior in these files, if i make the buffer > 8MB, OR if i move the linux base address away from 0xc080...., OR if i try and add a 2nd buffer region... the system won't boot correctly. the most common behavior is lockup either when it reaches "Uncompress..............................done," or when it tries to initialize the Intel EEPro 10/100 card, at which point it fails the self-test and the system generally panics. does anyone have any idea what i'm doing wrong? i'm careful to modify those values that should - such as base addresses of the SDRAM_PACKET and SDRAM_BASE, sizes, etc, but no matter how i try, i can't seem to make this work. has anyone been able to move the memory blocks around? thanks for any input, josh fryman

Ganesh, IXA SDK v2.0 will be released at the end of this month. Though perhaps you might not be able to order it until the first week of October. You will find the most current information on IXA SDK v2.0 at: http://developer.intel.com/design/network/products/npfamily/sdk2.htm Once it is available, there will be "Order Information" somewhere on the page.. most likely near the bottom.

There are no official rules. The goal of creating the project was to provide a place for people to share code with other interested parties. The code should be available for all to use so it should not have any licensing restrictions. --Dirk > -----Original Message----- > From: Lewin, Michael R [mailto:michael.r.lewin@intel.com] > Sent: Friday, September 07, 2001 4:56 PM > To: ixp1200(a)CS.Princeton.EDU > Subject: RE: [ixp1200] SourceForge project > > > Dirk, > what are the rules about posting code to sourceforge ?
