Recovering from a Failed Start on the S55
A system that does not start correctly might be attempting to boot from a corrupted FTOS image or from a
mis-specified location. In that case, you can restart the system and interrupt the boot process to point the
system to another boot location. Use the
setenv command, as described below. For details on the setenv
command, its supporting commands, and other commands that can help recover from a failed start, see the
BuBoot chapter in the FTOS Command Line Reference for the S55.
