Dear Marcel,

see tools/env for tools to read and write the U-Boot environment settings from Linux. This can be used to change the boot command, boot delay etc.
I used an AVR processor before and did this in the environment settings but currently that doesn't work for me yet. My env is in nor flash and I don't have a driver in linux yet to communicate with it. I'll look into this.
Linux MTD drivers for NOR flash are really standard; they should work out of the box on all architectures.
Currently I write settings to eeprom but have no idea if it can be read from u-boot. I currently only use it for items that I need in Linux. I did see some
Yes, you can do this. Use the "eeprom read" (or raw "i2c" commands) to read the eemprom content into RAM; then you can use "env import" to import it into the environment.
Or you can combine "env export" with "eeprom write" for the opposite direction.
Best regards,
