Dear Wolfgang Denk,
thanks for your mail.

Why should "flashing of uboot-environment" fail? If you configure for redundant environment, you should always at least have the previous copy of the settings).
Right, but what happens if user is doing something stupid? I don't have any connection to uboot at all, as in my final system there is no serial interface to change it back. If linux is not booting anymore I am lost, as this is my only known way to reflash uboot env, kernel, filesystem.
updates from TFTP server etc. - Have a look at the manual for details.
I would see tftpboot as a chance - but there are a few questions to me: - howto call this (and where?) in uboot code? It must be executed before reading the uboot-environment, as this can misconfigured. So it cannot be part of environment. - howto handle boot/kernel parameters? I only know the way via environment variables - the timeout has to set to be very small (as this otherwise in 99% slow down the boot process to much)
This tftpboot look smart - if I could manage this (see above).
Best regards Arno
