* Configuration is done via env variables bootmenu_delay and bootmenu_:
bootmenu_delay=
bootmenu_="=" (title and commands are separated by
first char '=')
is delay in seconds of autobooting first entry
is boot menu entry, starting from zero
is text shown in boot screen
are commands which will be executed when menu entry will be
selected
* First argument of bootmenu command override bootmenu_delay env
* If env bootmenu_delay or bootmenu argument is not specified, 10 seconds for
delay will be used
* If delay is 0, no entry will be show on screen, screen will not be cleared
and first entry will be called
* If delay is less then 0, no autoboot delay will be used
* Boot Menu will stop finding next menu entry if last was not defined
* Boot Menu always add menu entry "U-Boot console" at end of all entries
* Example using:
setenv bootmenu_0 Boot first kernel=bootm 0x8200 # Set first menu entry
setenv bootmenu_1 Boot second kernel=bootm 0x8300 # Set second menu
entry
setenv bootmenu_2 Reset board=reset # Set third menu entry
setenv bootmenu_3 U-Boot boot order=boot # Set four menu entry
(default u-boot boot script)
setenv bootmenu_4 # Empty string is end
of all bootmenu entries
bootmenu 20 # Run bootmenu with
autoboot delay 20s
