hOW to connect the DM9000 inDE2

[Altera_Forum]

Dear ALLL 

  I have a DE2 board. Now I want to use the DM9000. I want to know how to connect it to NIOSII . Beacuse I find the uClinux have a drive form DM9000. How to do it when I use the drive in hardware.pls help me !

Thanks hippo  

Now I find the SOPC builder have the DM9000 interface ,The next information is my hardward,the name is dm9000, so I will not change the name in dm9000.c in driver/net/    niosii DM9000  Addr[2]------------------------->[cmd]  [rd_n]---------------------------->[rd_n]  [cs_n]---------------------------->[cs_n]  [wr_n]---------------------------->[wr_n]  [irq]<------------------------------[irq]   but I got the next errors . <div class='quotetop'>QUOTE </div>  --- Quote Start ---  NET: Registered protocol family 16 Initializing Cryptographic API NIOS serial driver version 0.0 ttyS0 (irq = 1) is a builtin NIOS UART io scheduler noop registered io scheduler deadline registered dmfe_probe:eth0, 50000 Khz Nios dmfe_probe: eth0 VID: 0x2B2A2928 .ne. 0x90000A46 NET: Registered protocol family 2 IP: routing cache hash table of 512 buckets, 4Kbytes TCP established hash table entries: 512 (order: 0, 4096 bytes) TCP bind hash table entries: 512 (order: -1, 2048 bytes) TCP: Hash tables configured (established 512 bind 512) IPv4 over IPv4 tunneling driver GRE over IPv4 tunneling driver NET: Registered protocol family 17 Freeing unused kernel memory: 360k freed (0x119e000 - 0x11f7000) init started:  BusyBox v1.1.1-pre0 (2006.11.01-13:08+0000) multi-call binary   BusyBox v1.1.1-pre0 (2006.11.01-13:08+0000) Built-in shell (msh) Enter &#39;help&#39; for a list of built-in commands.# ifconfig eth0 192.168.1.30 netmask 255.255.255.0                                                   oom-killer: gfp_mask=0xd0                         DMA per-cpu: cpu 0 hot: low 2, high 6, batch 1 cpu 0 cold: low 0, high 2, batch 1 Normal per-cpu: empty HighMem per-cpu: empty  Free pages:        1196kB (0kB HighMem) Active:159 inactive:156 dirty:0 writeback:0 unstable:0 free:299 slab:934 mapped: 0 pagetables:0 DMA free:1196kB min:360kB low:448kB high:540kB active:636kB inactive:624kB prese nt:8192kB pages_scanned:1445 all_unreclaimable? yes lowmem_reserve[]: 0 0 0 Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pag es_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 HighMem free:0kB min:128kB low:160kB high:192kB active:0kB inactive:0kB present: 0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 DMA: 1*4kB 1*8kB 0*16kB 1*32kB 0*64kB 1*128kB 0*256kB 0*512kB 1*1024kB 0*2048kB 0*4096kB = 1196kB Normal: empty HighMem: empty Out of Memory: Killed process 40 (sh).[/b]  --- Quote End ---    why?

Please check nios wiki, 

http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux (http://nioswiki.jot.com/wikihome/operatingsystems/tryoutuclinux)  On the DE2 support disc, or you can download from Altera, there is a project with DM9000 enabled. DE2_System/DE2_demonstrations/DE2_NET/ You should check this first.  It may be differnet from the one in SOPC builder. ? In your boot message, it does not get the correct port address?

Hello, 

I was going through the Ethrnet page and the new config for the DM9000 on de2 is quite different from the one on the wiki. Instead of changing the dm9000x.c file I had to change the setup.c file in /kernel.   Also could any one please make it clear as to how one needs to add the hw_addr for DE2 board as I have to set the MAC address once the board is up and running and then go ifconfig up. to get any connection.

I shall update it later.  The DM9000A io address hook up for DE2 was fixed in later patches. Please remove old patch and add newer patch to find out if it can work without modify arch/nios2nommu/kernel/setup.c .  So, after all, you can set hw addr ? can bring up the DM9000 eth, ? can set static ip ?  If you want to add these initialization to rc, so that it will run after boot. then the file is vendors/Altera/nios2nommu/rc . add these commands to it.

Hello, 

I use dhcp to get an IP address from the server but yes I can set up the eth0 hw ether, It took some time but I got the MAC addr from the header file in the included-cd.    regards,

Hello, 

Once I make sure that the connection is proper I will to put it as an extension wiki page. Currently although running DHCP connection I am not able to connect to the telnet server running on the DE2. Once I am sure that I connect to this server from one of the computers. I will know what I am doing is right. And thus I wont make a mistake on the wiki page.   cheers,

Hello, 

This is the way to get DHCPclient running on your DE_board.  1.) Select dhcpcd-new nothing else as your client from the menuconfig-->User selection--> 2.) In the rc file get the Mac address set up using  ifconfing eth0 MAC-ADDRESS  3.) Still in the rc file just go dhcpcd &  4.) That should give you a IP from the server, It took me so long to get this working because my board is new and I had to register it with the admin. But I just stole the MAC-Address from the computer already hooked up and put that as the mac-address and thus instantly got assigned its IP.   Note: This is not a perfect method since /etc/dhcp/ directory does not exist in the romfs file system it would be good to have that since dhcpcd tries to write to this file.   Also dhcpcd-new says it works only for the 2.0 and 2.4 kernel it actually compiles for 2.6 and thus works fine.   Another way of doing this (a better way) is to use udhcp in busy-box but it needs a default.script file which needs to be written in either C-or-perl since sash cannot run bash scripts. I will post the udhcp method once I get it running.   regards,

[Altera_Forum]

Hello, 

The led keeps on flashing that means that your Dm9000A is being detected but that does not necessarily mean that you are hooked up to the network.   If you are using DHCP and not getting any ping to your board that means you are not hooked for sure. Why dont you change the MAc-address this way  This is if you are using DHCP: get the MAC-address of one of your computers hooked up to the network and running find its mac-address if you are on windows then use ipconfig on comman prompt should give you the MAc-address.  Unhook the computer from the network and set this mac-address as the mac-address for your borad by going ifconfig eth0 hw ether xx-xx-xx-xx-xx-xx (this is the computer mac-address). then go dhcpcd & (this should say something like unable to write to /usr/share/something... and if not able to connect timed-out  Next go ifconfig and it will show the new IP address obtained from the DHCP server. you should be able to ping it with your computer.  If you have a static IP then: again if you are going through the network get the IP from some other computer which actually works and set that as your IP (unhook this computer from the network)  ifconfig eth0 (new IP).  trying pinging it from your other computer using this IP. This should work  If all of this fails then: I would set up a straight socket connection with server running on the board and client running on the computer. Although this would need you to know raw-ethernet socket programming. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif good-luck.

madman23 Thank you  

 Now I think you maybe understand my question. I have do it OK in my DE2 board . I design a board using DM9000, The Sch is the same to DE2 . linux can be run in the same network , but when i use my new board . I find the LED2 Keep flash ,I don&#39;t know what&#39;s wrong . hardware ? sotfware?  could you help me ! thanks !
