Dear "Giuseppe Modugno",
In message 495A0644.29557.A6846B@g.modugno.elettronika.it you wrote:
I have a board running U-Boot/Linux. U-Boot program, two U-Boot environments, Linux kernel and root filesystem for Linux are stored in a NOR Flash.
I finished my developing process and now I want to copy the entire U- Boot environment to a new board. Of course, I don't want to manually copy all the variables in the environment.
Is there a simple way to dump the full environment in a file and copy it in the new board?
Assuming both boards have the same configuration (or, more precisely, at least the same size of environment and environment sectors), then you can just read the sector(s) containing the environment from their corresponding /dev/mtd* devices in Linux and copy it to the other system.
Best regards,
Wolfgang Denk
