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 a lot for your hint, but unfortunately it doesn't solve my  
- downloaded from;
- called "make ARCH=powerpc CROSS_COMPILE=ppc_6xx-  
- 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:

=> bootm
## Booting kernel from Legacy Image at 01000000 ...
    Image Name:   Linux-
    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

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.
