<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The device name you should use in the
CONFIG_CMDLINE “root=…” can be found in the routine call to
register_blkdev() in the driver source code. The first parameter to
register_blkdev() is the major number of the device. The second parameter is
the name of the device, as in /dev/xsda2, or /dev/xsysace2. This second
parameter will contain just the ‘xsda’ or ‘xsysace’ in
it, and it may be a preprocessor constant defined earlier in the file, such as #define
MAJOR_NAME “xsda”, but it might not be a constant either. It
depends on the code.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

I am using that driver very well now. There is only one problem. It seems <br>
that the driver for TEMAC only support Gigabit Enet, not 10/100/1000M <br>
adapted. But because I want to use the Gigabit enet, I don't care that. So <br>
it's OK, at lease for 1Gbit/s.<br>
<br>
So I don't think Pradeep's problem is caused by Temac. I still suspect that <br>
he didn't pass a right parameter to "root=", just like what I posted <br>
before.<br>
