I'm sorry for the misunderstanding. Linux really runs on my board, but only after I store the kernel and the root filesystem on the Flash memory. And to do these operations, I must have a good U-Boot environment. So I have a source board with a good U-Boot environment and Linux, and a destination board (picked from the shelf) with just U-Boot and its default environment (no Linux runs on it). I can copy the good U-Boot environment from the source board to a file by using Linux, but I can't use Linux on the destination board to store the good environment in the memory. I think the best solution is to use Linux on the source board to copy the good U-Boot environment in a image file. On the destination board, I can download (by tftp) the image and store it on the Flash at the correct address. In this way, I'll use only U-Boot on the destination board to retrieve the good environment. From that, I can install kernel and root filesystem. > > Another possibility is to printenv on the source board, copy the > > text result from the terminal into a text file, append "setenv " at > > the top of each lines, substitute = character with space, insert the > > quotes where needed and paste the result in the terminal of the > > destination board. > > You could (and probaly should) put the constant part of your > definitions into the default environment, and use a script image for > the rest. Just now I'm reading about the scripting capabilities of U-Boot. It's interesting. Starting from which U-Boot version they are available? Just another question. I have two redundant U-Boot environments. Should I copy both of them in two different images, or are they the same and I can copy the first into the second?
