Hi,
paste from the doc/README.autoboot
CONFIG_BOOT_RETRY_TIME
CONFIG_BOOT_RETRY_MIN
bootretry environment variable
These options determine what happens after autoboot is
stopped and U-Boot is waiting for commands.
CONFIG_BOOT_RETRY_TIME must be defined to enable the boot
retry feature. If the environment variable 'bootretry' is
found then its value is used, otherwise the retry timeout is
CONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and
defaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds.
If the retry timeout is negative, the U-Boot command prompt
never times out. Otherwise it is forced to be at least
CONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is
entered before the specified time the boot delay sequence is
restarted. Each command that U-Boot executes restarts the
timeout.
end of paste from the doc/README.autoboot
Currently is used function simple_strtoul() for parsing the bootretry
enviroment variable. It fails if the bootretry is negative. The attached
patch should fix it.
