problem with dm9000a

[Altera_Forum]

Hello everyone: 

 I want to enable network of uClinux on my custom board, but there seems to be some problem..  1, I can&#39;t see the "<DM9000x> I/O: 80900090, VID: 90000a46 and eth0" message during the boot up process; 2, When I use ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx command, it shows "SIOCSIFHWADDR: no such device".  By the way,I use dm9000a on my board, and I enable the "davicom dm9000 10_100 Ethernet chip support" in kernel. My uClinux version is Microtronix Nios II Linux Distribution V1.4, and the kernel is 2.6.11.  Who knows how to solve the problem, please give me some suggestions, thanks. I suspect the device driver can&#39;t support dm9000a but only dm9000, but I&#39;m not sure..    0quanquan0

You can use uClinux-dist-20070130 with nios2 patches. The dm9ks is a updated driver for DM9000A. 

Please find it in the wiki.

Hi hippo: 

Thank you for your help.  But the link for uClinuxdist070130 is not available now. The leader and the project is waiting for me...I am so upset.  Can you just send the dm9ks.h and dm9k.c to me?  My email is denghuan5608@gmail.com  Thanks very much!!!  Sincerely  0quanquan0

It seems their server is down. 

You can find the dm9ks in nios2 patches to it. http://nioswiki.jot.com/wikihome/operating...ios2-02.diff.gz (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist/uclinux-dist-20070130-nios2-02.diff.gz)  I am sending 20070130 to a file sharing host. wait a moment.

Since you are using a custom board, have you tested the io ports access of the chip? 

You should check the hardware first.

I recalled that I had tested the DM9000A on a DE2 board using the dm9000x.c in 2.6.11 kernel. 

So the old driver should work.

Hi hippo: 

Thank you very much. I have downloaded the .diff file.   Now the situation is I don&#39;t have uClinuxdist enviroment in my computer(But I will learn and use it soon..). To solve my current problem, can you tell me how can I get the dm9k.c from the .diff?  Excuse for my stupid question, thanks again...  Sincerely 0quanquan0

gunzip uClinux-dist-20060803-nios2-02.diff.gz 

you will get uClinux-dist-20060803-nios2-02.diff edit this file, and you can find dm9ks stuff. note you need to update arch/nios2nommu/setup.c, drvers/next/ Spcae.c, Makefile and Kconfig.  But I wonder there are problems in your hardware, so you should try to add some debug messages and dump in the old dm9000x.c . Using a new driver won&#39;t work on a bad hardware.  And the link to uClinux-dist-20070130, http://s4.quicksharing.com/v/2589078/uclin...30.tar.bz2.html (http://s4.quicksharing.com/v/2589078/uclinux_dist_20070130.tar.bz2.html)

Well, you are very close to add the dm9ks driver. But please put it away for a while. 

 I said, "I had tested the DM9000A on a DE2 board using the dm9000x.c in 2.6.11 kernel.". That is the one of Microtronix release 1.4.  The DM9000 and DM9000A , both chips have the same Vendor/Product ID. And they can use the same drivers, dm9000x or dm9ks.  The things what you should do at this moment is, adding debug message to your dm9000x.c , in the dmfe_probe() function,   Index: dm9000x.c =================================================================== --- dm9000x.c (revision 12) +++ dm9000x.c (working copy) @@ -414,6 +414,11 @@  // id_val |= inb(iobase + 4) << 24;  id_val |= ior(db, DM9000_PID_H) << 24;   + printk("<DM9000> debug %s I/O: %x, VID: %x \n", + dev->name, + iobase, + id_val); +  if (id_val == DM9000_ID) {    printk("<DM9000> %s I/O: %x, VID: %x \n",  If it does not even display this debug message, then check if you config this driver correctly.  If it displays strange ID value, change the detection to loop for ever, check your hardware, with a scope or signal-tap.  In the long run, you should really setup a Linux PC and build uClinux-dist.
