If it's really urgent you should consider engaging commercial support. This would probably be the fastet nd most reliable way to solve your issue quickly. As far as free community support is concerned, this is all done on a voluntary base, and you might even run into the effects described here: http://catb.org/esr/faqs/smart-questions.html#urgent > Please let me write what I understood from your idea.

You should try and read some documentation to get a better understanding of the terms. CONFIG_* variables are compile-time settings. They determine what get's built into the U-Boot image running on your target. This is different from envrionment variables, which can be loaded, changed, and stored in the running system. The only relation between the two is that you can use CONFIG_ settings to define thedefault environment which gets used when no valid environment can be found. > Next, when the u-boot is booted the environment variables should be > imported from Compact Flash. > This is done in two steps: > 1. ide read (read the u-boot config from Compact Flash to RAM ?) > 2. env import (import u-boot config from RAM to u-boot?) Right. > Could you please give me more hints which CONFIG macros should/could be > used for the above mentioned steps. This has nothing to do with any CONFIG_ settings. Of Course I assume that the "ide" command is enabled in your configuration so you can access the CF card. > Is there any command to import/export u-boot config. Yes, as noted: "env import" and "env export". Try "help env". > So far I was using saveenv to export/save u-boot config into Flash? "saveenv" ist just an alias for "env save", whichis a somewhat specialized version of "env export" (and which is not enabled in your system when you define CONFIG_ENV_IS_NOWHERE).
