Hi,<br><br>All the new development is happening in arch/powerpc&nbsp; architecure. So it is good to use this architecure if you are upgrading the kernel. But it might not work with kernel 1.1.2, As arch/powerpc need a structure like open firmware for the parameters.
<br><br><br>If you want to stick to 1.1.2 u-boot version then you shall use arch/ppc architecure.<br><br>Regards<br>Bhupi<br>&nbsp;<br><br><div><span class="gmail_quote">On 6/27/07, <b class="gmail_sendername">Bizhan Gholikhamseh (bgholikh)

<div><font face="Arial" size="2"><span>Hi 
All,</span></font></div>
<div><font face="Arial" size="2"><span>Sorry for asking 
this question again, I am still not clear on some of the 
issues.</span></font></div>
<div><font face="Arial" size="2"><span>Background:</span></font></div>
<div><font face="Arial" size="2"><span>We have developed 
a&nbsp;custom board based on Freescale reference board: MPC8555_CDS&nbsp;with 
MPC8541E processor running Linux 2.6.11 and uboot 1.1.2 
version.</span></font></div>
<div><font face="Arial" size="2"><span>&nbsp;</span></font></div>
<div><font face="Arial" size="2"><span>I would like to 
update the Linux kernel to the latest available kernel 
2.6.21.</span></font></div>
<div><font face="Arial" size="2"><span>Here are my 
questions:</span></font></div>
<div><font face="Arial" size="2"><span>1- Should I use 
ARCH=ppc or ARCH=powerpc to build the kernel?</span></font></div>
<div><font face="Arial" size="2"><span>2- I have seen 
similar filenames under arch/ppc and arch/powerpc, which one applies to 
MPC8541E?</span></font></div>
<div><font face="Arial" size="2"><span>3- Once I build the 
kernel, could I load the kernel with uboot version 1.1.2 or not? if not what I 
should do?</span></font></div>
<div><font face="Arial" size="2"><span></span></font>&nbsp;</div>
<div><font face="Arial" size="2"><span>Many thanks in 
advance,</span></font></div>
