Wolfgang
Thanks for the help so far. Ok. A little background. I'm completely new to the boot loader myself. The company that developed the prototype for us was a third party who we do not have a contract with anymore so the "new guy" is stuck trying to figure out what is going on.
It looks like they defined the environment variables (ip address, hostname etc) in the /include/configs/at91rm9200dk.h. From your previous email, I gathered that they probably should not have done this (meddle with this file). Or maybe there I could be getting something wrong somewhere. Not entirely sure which the board config file is but there are 2 files I suspect, the first is the fw_env.h ( I guess this the header file - should I define the preboot there?) or the other config file is under etc / fw_env.config but has only one line in it "/dev/mtd2 0x0000 0x10000 0x20000"
Anyway, the way I see it, since they defined the environment variables in /include/configs/at91rm9200dk.h and it has been working fine (bar the bad crc), maybe I should just go ahead and define the config preboot there as well. A couple of questions if I do this:
1. Will the command be seen or picked up from here? And if not? Where will it be picked up? 2. What exactly will the command do? 3. Is this the correct syntax: #define CONFIG_PREBOOT "setenv preboot 'setenv preboot;saveenv';" Or do I have too many quotation marks in here?
Thanks a lot
Solomon

-------------------^^ typo
Try CONFIG_PREBOOT instead...
- And also can you verify that I would add this line in the file that

Include/configs/at91rm9200dk.h is the configuration file for the old evaluation kit; I don;t think you should meddle with this file. You should have your own board config file instead.
