Re: Compile new kernel for 5200B w/ ELDK

I had the same problem as you.

For what its worth, here is what I added to the end of my .dts file to get my console working for a MPC8347 embedded systems

chosen {
        linux,stdout-path = &serial0;
};

Also, since I use uboot and not OF, I load the cuImage file instead of the uImage file


thanks

Hi Detlev:

Use a recent kernel version.  2.6.26 should work out of the box  
without too much hassle.  Some of the older versions had problems  
effectively stalling Linux very early without any output on the  
console.

Thanks a lot for your hint, but unfortunately it doesn't solve my  
problem:
- downloaded 2.6.26.3 from kernel.org;
- called "make ARCH=powerpc CROSS_COMPILE=ppc_6xx-  
52xx/lite5200b_defconfig";
- called "make ARCH=powerpc CROSS_COMPILE=ppc_6xx- uImage".

However, even with "console=ttyPSC0,115200 verbose panic=1" in the  
bootargs, the kernel simply doesn't say /anything/ after decompression:

<snip>
=> bootm
## Booting kernel from Legacy Image at 01000000 ...
    Image Name:   Linux-2.6.26.3
    Created:      2008-09-02   9:11:12 UTC
    Image Type:   PowerPC Linux Kernel Image (gzip compressed)
    Data Size:    1341904 Bytes =  1.3 MB
    Load Address: 00000000
    Entry Point:  00000000
    Verifying Checksum ... OK
    Uncompressing Kernel Image ... OK
</snip>

Do I understand the remark in  
Documentation/powerpc/booting-without-of.txt, section "The /chosen  
node", correctly that it is *not* necessary to add it to the dts file  
as u-boot 1.3.4 should fill it in automatically?  Anyway, adding this  
section doesn't change anything...

HELP!  I'm really lost here...

Thanks, Albrecht.
