Accessing SRAM in IXP2400
by Romit Dasgupta 14 Jan '04

14 Jan '04

Hi, I am using MVista IXDP2400 preview kit on a Radisys board (IXP2400). The board has DRAM at 0x0x00000000-0x10000000 (256M). SRAM Channel 0 (4M) : 0x80000000-0x80400000 SRAM Channel 1 (4M) : 0x90000000-0x90400000 When I boot linux, it can be seen that the kernel is loaded into 0xc0000000 and its alloted a total of 64M in DRAM space. I could not see SRAM at all. To enable SRAM I passed mem=64M mem=4M@0x80000000 in the command line. After compiling the image and loading it I could see that the kernel has 68M but before the root file system could be enabled many of the ioremaps (used by network driver like eepro100) are failing. This failures result in the inability to activate some PCI devices (network card) and thus cannot load the root file system over NFS. Here are the console logs. I have marked some relevant messages by ^^^^^^ Memstart: c000000 Memsize: 4000000 ^^^^^^^^^^^^^^^^^^ Node: 0 Memstart: 80000000 Memsize: 400000 ^^^^^^^^^^^^^^^^^^ Node: 0 On node 0 totalpages: 17408 zone(0): 476160 pages. zone(1): 0 pages. zone(2): 0 pages.

I understand the memory locations SRAM & DRAM are discontiguos. I tried doing ioremap and could access SRAM but I feel that ioremap is only a temporary way to access SRAM. The funny thing is that when I also try to enable SRAM channel 1 by mem=64M mem=4M@0x80000000 mem=4M@0x90000000 the system halts after saying Booting the kernel.. __ioremap(0x80000000, 4*1024*1024,0) and later __iounmap works. Not sure if this is the right way to do it. And I havent digged into why ioremaps by PCI devices in the eariler case fails. Any insight will be very useful. Thanks in advance, -Romit

Running sample application on ENP2611 board
by Ning Weng 09 Jan '04

09 Jan '04

Folks, Recently we got ENP2611 board based on IXP2400. After successfully installed and boot, we are confused to run a simple sample application on the hardware. It is really different with our previous one- ENP2505 based on IXP200. Can you share your experience of playing ENP2611 or kindly point me the right documentation for it? Thanks in advance, Ning

Can you share your experience of playing ENP2611 or > kindly point me the right documentation for it? [ Disclaimer: I don't use an ENP2611 board ] What do you mean by "running a sample application"? If you have the Intel SDK, you should have access to Intel Software Framework with reference designs that contains a lot of sample code (at least, we have those reference designs for IXMB 2400 reference board). Regarding programming issues, you should read the IXP2400/2800 Programming book, from Intel press. A quite good introduction. I hope it helps a little, yours, david -- David Mentré <mentre(a)tcl.ite.mee.com> - Research engineer (Ph.D.) Mitsubishi Electric ITE-TCL / European Telecommunication Research Lab Phone: +33 2 23 45 58 29 / Fax: +33 2 23 45 58 59 http://www.mitsubishi-electric-itce.fr

Hi, While trying to configure the dhcp based on the following instructions from linux setup guide for ENP from Radisys: Q.1.How do i find the mac address of the ENP board? I did a /sbin/ifconfig but it shows the ip and mac of only the NIC card installed on it. Thanks, 4.4.Configure DHCP The DHCP protocol should be configured to supply an IP address to the ENP system using the BOOTP protocol. 1. Edit or create the configuration file /etc/dhcpd.conf adding Set a.b.c.d to your subnet address Set e.f.g.h to your subnet mask Set i.j.k.l to your gateway address Set m.n.o.p to your target IP address Set xx:xx:xx:xx:xx:xx to your ENP MAC address. allow bootp; subnet a.b.c.d netmask e.f.g.h { default-lease-time 1209600; max-lease-time 31557600; option routers i.j.k.l; group { host enp_linux.radisys.com { hardware ethernet xx:xx:xx:xx:xx:xx; fixed-address m.n.o.p; } } } -Darshan _________________________________________________________________ Grab our best dial-up Internet access offer: 6 months @$9.95/month. http://join.msn.com/?page=dept/dialup

Problem of installing vmware at Redhat Linux 7.3
by Ning Weng 15 Dec '03

15 Dec '03

Hello, In attempting to install VMware on Redhat Linux 7.3 I got the message "What is the location of the C header files that match your running kernel [/usr/src/linus/include]? It doesn't like /usr/src/redhat or /usr/lib or /usr/include. One of the messages is that it is looking for "linux" "asm" "net" and can't find them, although I can see them. Another message is that the directory has the wrong version kernel and is needs the correct one. What is the best thing for me to do? Thanks, -Ning
