I've been trying to build the linux 2.6.23 kernel for the PPC405 on the xilinx ml403.  I copied over my xparameters.h and xparameters_ml40x.h files and added the following options through menuconfig.  
<li>Enable loadable module support: DISABLE 
<li>Processor: 
<ul>
<li>Type 40x 
<li>Math emulation: ENABLE 
<li>IBM 40x options: 
<ul>
<li>Machine Type: &quot;Xilinx-ML403&quot; </li></ul></li></li></li></ul>
<li>Platform options: 
<ul>
<li>Kernel command line: &quot;console=ttyUL0 root=/dev/ram&quot;&nbsp;</li></ul>
<li>Bus options: 
<ul>
<li>PCI support: DISABLE 
<li>PCCARD (PCMCIA/CardBus) support: 
<ul>
<li>PCCARD (PCMCIA/CardBus) support: DISABLE </li></ul></li></li></ul>
<li>Drivers 
<ul>
<li>Block Devices: 
<ul>
<li>Xilinx SystemACE support: ENABLE </li></ul>
<li>Character devices: 
<ul>
<li>Serial drivers: 
<ul>
<li>Xilinx uartlite serial port support: ENABLE 
<li>Support for console on Xilinx uartlite serial port: ENABLE </li></li></ul></li></ul></li></li></ul></li>
<div>I then ran make bzImage and got the following errors.&nbsp; I&#39;m guessing there are two options I chose that conflict.&nbsp; Any insight?</div>
