Ok.

Good idea, but let's use a more general name and not restrict it to LCD; I'll set up a u-boot-video repo. Please send me your public SSH key.

I'll send it privately. :)

Thanks,

For cloning you can use http (or even rsync) as well. But to push your changes back, you need SSH (+ git).

Sorry, it doesn't work on my side.

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 1.2.0
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
	http://www.denx.de/wiki/UBoot/CustodianGitTrees

Please review and comment. [Note: this is a wiki. Instead of sending
your comments by e-mail, you also edit this document yourself.]

	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
