* Added some ANSI escape codes definitions in common.h
* Configuration is done via env variables bootmenu_delay and
bootmenu_num:
bootmenu_delay=delay
bootmenu_num=title=commands
(title and commands are separated by first char '=')
delay is delay in seconds of autobooting first entry
num is boot menu entry, starting from zero
title is text shown in boot screen
commands are commands which will be executed when menu entry is
selected
Do you need this command if you already have common/menu.c?
M
* First argument of bootmenu command override bootmenu_delay env
* If env bootmenu_delay or bootmenu arg is not specified, delay is 10
seconds * If delay is 0, no entry will be shown on screen and first 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 1. kernel=bootm 0x8200 # Set first menu
entry setenv bootmenu_1 Boot 2. 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 fourth menu
entry setenv bootmenu_4 # Empty string is end of all bootmenu entries
bootmenu 20# Run bootmenu with autoboot delay 20s
