Hi All, Has anybody tried out memory accesses on pci devices connected to IXP1200EB pci slots? I have interfaced a DAQ on one of the pci slots. VxWorks is able to detect the card and also assign BARs to it. But I dont see any BSPs using which I can easily read from the card. The card is being mapped (memory mapped) at addresses: - bus 0 dev 8 error 0 id 10932A80 size 00001000 addr 02201000 size 00001000 addr 02202000 Does the region in memory (above 1Mb, or 16MB or something like that) have any effect on the way memory read/write is done? What documentation do I refer to in order to find out how to read and write to memory in VxWorks. Regards, Sandeep.

Sandeep: did anyone from Intel respond to this?

Is anybody in possession of the image file for the Intel supplied firmware? It can easily be created using the existing firmware running from flash.

Mahesh, I'll assume that you are running the VERA microcode; we never ran the microcode in simulation, so I am not sure what the real answer is. However, this might correspond to a problem we've been having on real hardware where the ready bits are stale as we read them, so we get bad data from the FIFO. Unfortunately I don't know a good solution for this problem.

I've the same equipment as yours and I've used it to program the flash a number of times. You have to first erase it and then write it. >From: Sandeep P <sandeep.padmanabhan(a)asu.edu> >Reply-To: ixp1200(a)CS.Princeton.EDU >To: ixp1200(a)CS.Princeton.EDU >Subject: [ixp1200] Problem with programming the flash >Date: Fri, 14 Jun 2002 02:22:57 -0700 > >Hi All, > I am currently trying to program IXP1200 flash with the Intel >firmware.

I guess you tried to erase the flash then write to it as well. peggy -----Original Message----- From: Sandeep P [mailto:sandeep.padmanabhan@asu.edu] Sent: Friday, June 14, 2002 2:23 AM To: ixp1200(a)CS.Princeton.EDU Subject: [ixp1200] Problem with programming the flash Hi All, I am currently trying to program IXP1200 flash with the Intel firmware.

Problem with programming the flash
by Sandeep P 14 Jun '02

Hi All, I am currently trying to program IXP1200 flash with the Intel firmware. I am using flash burner equipment called Topmax which is from the company EEtools. Inspite of following the instructions as mentioned in the manual I am unable to write to the flash. Read from flash is successful, but writes are not happening. Have any of you faced a similar problem? Do I need to take some extra steps before writes are allowed? The device continuously makes attempts to write but in the end is unable to write anything.

You should already have this!

evaluation board replacement?
by Mirko Benz 12 Jun '02

12 Jun '02

Hi, We are facing some problems with our evaluation boards (B0 step) due to a PCI bug in the IXP. I have heard that one can get these boards upgraded to C0 silicon by INTEL. Is this true? Any pointer? Regards, Mirko Benz
