I guess one could use an existing system on the plug to set up U-boot to boot d-i over TFTP and use a network console to install. However this is probably too complex (and fragile) for most users. > Since I wrote that, a better version[1] called kwboot (although I think > the name may be about to change) has been independently written and > incorporated into the u-boot source code.

Your version has the advantage of being small and self-contained; thus easy to build for anyone who needs it. Building all of U-boot needs a working cross toolchain which means extra work for a user. What is missing at the moment for a normal user to be able to upgrade U-boot are some pre-built "blessed" binary images of the bootloader, ideally hosted on a Debian machine. The following files are required to upgrade the bootloader using the UART method: - u-boot.kwb built with BOOT_FROM=uart to boot via UART - u-boot.kwb build with BOOT_FROM=spi to flash the device I can build known-good versions of these using either the latest (2013.01.01) U-boot or the version in wheezy, if someone can arrange to have these hosted on an official site? After that the steps for installation are fairly straightforward: 1) Download the U-boot images. 2) Download and build kwuartboot, boot and flash the new U-boot using UART. 3) Copy d-i to an USB stick and follow the steps from my previous e-mail.
