Title: Native Compilation Of Sl-c860 Kernel
Post by: danr on July 04, 2005, 07:42:41 am

Hi,

Has anyone managed to compile the SL-C860 kernel natively?  I don't have access to a linux machine so I'm trying to compile the kernel on my Zaurus.  I've examined the pdaXrom builder here (http://mirror1.pdaxrom.org/source) and looked at the instructions here (http://212.10.30.205/docs/pdaxrom-builder/build-rom-yourself), and can compile the kernel after applying all the patches (in order!) and using the configuration, kernel-2.4.18-boxer-cacko.  For the compilation I'm using gcc 2.95.2 and binutils 2.9.5, from the zgcc cramfs.

The zImage in arch/arm/build builds but when I rename it to zImage.bin, add it to the pdaXrom tools.tar and flash with it, on reboot the system hangs without any messages.  Fortunately I can re-flash with the old version because during the pdaXrom flash routine I go to the command line and copy the original tools.tar back to the CF card.

Has anyone managed to compile a working kernel?  Am I missing something obvious here?

Cheers,

Dan

pdaX86 is a Live Linux distrib. You can boot it and have the dev. enviroment setup in a minute. Crosscompiling the kernel is much faster and easier than trying to build it natively. I crossbuilt a kernel once, but I haven't tried to boot it, I only needed some new modules from it. I think it worth the try to setup a cross enviroment on your desktop computer than stuggling with the native compile.

Here's the pdaXrom LiveCD image:

It does sound easier to do a cross-compile using the pdaXrom LiveCD image, but the problem is that the only PC I have access to at the mo is the Windows one I use at work, and I don't particularly want to start booting Linux on it    

Perhaps when I get access to a PC at home again I'll give it a go, after downloading the necessary files at work first.  But I just wondered if anyone had done this natively.

Out of interest, compiling the kernel on my Zaurus takes just under an hour; cross-compiling on my work machine (using Cygwin) takes 1.5h.

Cheers,

Dan

Hi :-)

... any chance to get this image for intel or via c3 cpu ?

Thanks
