&gt; I use it. And it is: #define CPM_FCC_SPECIAL_BASE &nbsp; &nbsp; &nbsp;
&nbsp;((uint)0x0000b000)<br>

&gt;<br>
&gt; Hi!<br>
&gt;<br>
&gt; &nbsp;Do you use CPM_FCC_SPECIAL_BASE constant? (include/asm-ppc/cpm2.h)<br>
&gt; &nbsp;In my case (8250, 8260) FCCs only works when it is set to 0x3000...<br>
&gt;<br>
&gt;<br>
&gt; &nbsp;2007/7/4, li.chunlin@zte.com.cn &lt;li.chunlin@zte.com.cn&gt;:<br>
&gt; &nbsp;&gt;<br>
&gt; &nbsp;&gt; hello, every one<br>
&gt; &nbsp;&gt;<br>
&gt; &nbsp;&gt; &nbsp; &nbsp;I have a board with mpc8270. And there are
two ethernet interface by<br>
&gt; fcc1<br>
&gt; &nbsp;&gt; and fcc2. Now in linux kernel 2.6.14 fcc1 is ok, but fcc2
is some wrong.<br>
&gt; I<br>
&gt; &nbsp;&gt; set loopback of fcc2 or rmii. that's ok. But i set loopback
in phy, it is<br>
&gt; &nbsp;&gt; wrong. But fcc2 is ok in u-boot.<br>
&gt; &nbsp;&gt;<br>
&gt; &nbsp;&gt; I take a look with oscillograph. i find that there is signal
from fcc2 to<br>
&gt; &nbsp;&gt; phy and there is signal from phy to fcc2 in data pins.
But fcc2 cannot<br>
&gt; &nbsp;&gt; receive data and fcc2 can send data.<br>
&gt; &nbsp;&gt;<br>
&gt; &nbsp;&gt; who know the reason? Can you tell me?<br>
&gt; &nbsp;&gt;<br>
&gt; &nbsp;&gt; thanks.<br>
