Hello,<br>
<br>
I am trying to port linux on my Powerpc Board. I have used Linux 2.6.26 and gcc <a href="http://3.4.5.">3.4.5.</a><br>
I have used Uboot 1.2.<br>
Linux seems running from _start to udbg_early_init(). That&#39;s why I develloped a udbg_driver.<br>
It must write in a register which is located at 0x2001b044. So I wrote :<br>
<br>
void __iomem *p;<br>
p=ioremap(0x2001b044,4);<br>
iowrite32(&#39;O&#39;,p);<br>
iowrite32(&#39;K&#39;,p);<br>
<br>
But when he exectuted ioremap, he looped in the __delay function.<br>
<br>
Can you help me to solve this probleme ?<br>
<br>
