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,
Rodolfo

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 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
