You are right but after putting some delays around the code I
preferred to use this ??dirty hack! :)
However as soon as I have more free time I'll try to find out where
exactly I should add the delay.

Hi Wolfgang,
Of course, you are right. But I have to admit that I'm a little bit
overburdened in that. 
I found a how-to for customizing u-boot for my own board. I followed the 
Steps and "only" the configuration file is missing. If its don't working,
I can at least exclude that point. 
Is there maybe a patch or something else to get the necessary files?
Thanks for advance
Best regards,
Frank

Could anybody send me a working <board.h> configuration file for our
MPC8343m board. I tried to modify some similar configs in the U-Boot

package but no one works. I spent meanwhile 2 days to get this working.
Porting U-Boot to new hardware requires more (much more!)  than  just
copying a board config file.

Hello,
based on earlier input from Peter Pearse  (thanks,  Peter!)  I  added
some  initial  draft  for  a  descritpion  of  the U-Boot development
process. You can find it at

Please review and comment. [Note: this is a wiki. Instead of sending

Hi Doug,
Are you using linux kernel?  When you comment out 'enable
address translation', can you successfully boot with linux kernel?
When I comment out those line, it did help to boot until u-boot console
shows up, but it failed to continue boot up with linux kernel.  To make
linux kernel working, I have to keep following old 1.1.3 version code
in, which will cause another problem.  Did you have similar problem?
Thank you and best regards

Hi Dongy,
I do not use Linux; I run QNX Neutrino.  But I did have a similar
problem
running QNX when I switched to U-Boot 1.1.4 and beyond.  U-Boot began
leaving the data cache enabled with that version.  Note that the last
part
of 1.1.3 snippet that you still use (above) disables the data cache.
I fixed it for QNX by adding "CFG_COMMAND_CACHE" to 
"CONFIG_COMMANDS" in my board header file in include/configs, and 
adding "dcache off; " to the appropriate spot in the bootcmd environment
variable.  In my case,
#define CONFIG_BOOTCOMMAND "tftp ${loadaddr} ${ifsfile}; " \
    "dcache off; " \
    "go ${loadaddr}"


Since my disable address translation trick got your U-Boot up and
running, I suggest trying my data cache hack for Linux and reporting
back.
Regards,
Doug
