In U-Boot werden die vom -Keyboard-Controller gelesenen Daten hexadezimal codiert in der auto- -matisch angelegten Environment-Variablen "keybd" übergeben.

B. in einem Device-Treiber oder -einer Applikation ausgewertet werden. - - -Sonderfunktionen beim Booten: - -Es lassen sich eine oder mehrere (beliebig viele) Tasten oder Tasten- -kombinationen definieren, die Sonderfunktionen auslösen, wenn diese -Tasten beim Booten (Reset) gedrückt sind. - -Wird eine eingestellte Taste bzw. Tastenkombination erkannt, so wird -in U-Boot noch vor dem Start des "Countdown" und somit vor jedem an- -deren Kommando der Inhalt einer dieser Taste bzw. Tastenkombination -zugeordneten Environment-Variablen ausführen. - - -Die Environment-Variable "magic_keys" wird als Liste von Zeichen ver- -standen, die als Suffix an den Namen "key_magic" angefügt werden und -so die Namen der Environment-Variablen definieren, mit denen die -Tasten (-kombinationen) festgelegt werden: - -Ist "magic_keys" NICHT definiert, so wird nur die in der Environment- -Variablen "key_magic" codierte Tasten (-kombination) geprüft, und -ggf. der Inhalt der Environment-Variablen "key_cmd" ausgeführt (ge- -nauer: der Inhalt von "key_cmd" wird der Variablen "preboot" zugewie- -sen, die ausgeführt wird, unmittelbar bevor die interaktive Kommando- -interpretation beginnt). - -Enthält "magic_keys" z. B. die Zeichenkette "0123CB*", so werden -nacheinander folgende Aktionen ausgeführt: - - prüfe Tastencode ggf. führe aus Kommando - in Variable in Variable - ----------------------------------- - key_magic0 ==> key_cmd0 - key_magic1 ==> key_cmd1 - key_magic2 ==> key_cmd2 - key_magic3 ==> key_cmd3 - key_magicC ==> key_cmdC - key_magicB ==> key_cmdB - key_magicA ==> key_cmdA - key_magic* ==> key_cmd* - -Hinweis: sobald ein aktivierter Tastencode erkannt wurde, wird die -Bearbeitung abgebrochen; es wird daher höchstens eines der definier- -ten Kommandos ausgeführt, wobei die Priorität durch die Suchreihen- -folge festgelegt wird, also durch die Reihenfolge der Zeichen in der -Varuiablen "magic_keys". - - -Die Codierung der Tasten, die beim Booten gedrückt werden müssen, um -eine Funktion auszulösen, erfolgt nach der Tastaturtabelle. - -Die Definitionen - - => setenv key_magic0 3a+3b - => setenv key_cmd0 setenv bootdelay 30 - -bedeuten dementsprechend, daß die Tasten mit den Codes 0x3A (Taste -"F1") und 0x3B (Taste "F2") gleichzeitig gedrückt werden müssen. Sie -können dort eine beliebige Tastenkombination eintragen (jeweils 2 -Zeichen für die Hex-Codes der Tasten, und '+' als Trennzeichen). - -Wird die eingestellte Tastenkombination erkannt, so wird in U-Boot -noch vor dem Start des "Countdown" und somit vor jedem anderen Kom- -mando das angebene Kommando ausgeführt und somit ein langes Boot- -Delay eingetragen. - -Praktisch könnten Sie also in U-Boot "bootdelay" auf 0 setzen und -somit stets ohne jede User-Interaktion automatisch booten, außer, -wenn die beiden Tasten "F1" und "F2" beim Booten gedrückt werden: -dann würde ein Boot-Delay von 30 Sekunden eingefügt. - - -Hinweis: dem Zeichen '#' kommt innerhalb von "magic_keys" eine beson- -dere Bedeutung zu: die dadurch definierte Key-Sequenz schaltet den -Monitor in den "Debug-Modus" - das bedeutet zunächst, daß alle weite- -ren Meldungen von U-Boot über das LCD-Display ausgegeben werden; -außerdem kann man durch das mit dieser Tastenkombination verknüpfte -Kommando z. B. die Linux-Bootmeldungen ebenfalls auf das LCD-Display -legen, so daß der Boot-Vorgang direkt und ohne weitere Hilfsmittel -analysiert werden kann. - -Beispiel: - -In U-Boot werden folgende Environment-Variablen gesetzt und abgespei- -chert: - -(1) => setenv magic_keys 01234#X -(2) => setenv key_cmd# setenv addfb setenv bootargs \\${bootargs} console=tty0 console=ttyS1,\\${baudrate} -(3) => setenv nfsargs setenv bootargs root=/dev/nfs rw nfsroot=\${serverip}:\${rootpath} -(4) => setenv addip setenv bootargs \${bootargs} ip=\${ipaddr}:\${serverip}:\${gatewayip}:\${netmask}:\${hostname}::off panic=1 -(5) => setenv addfb setenv bootargs \${bootargs} console=ttyS1,\${baudrate} -(6) => setenv bootcmd bootp\;run nfsargs\;run addip\;run addfb\;bootm - -Hierbei wird die Linux Commandline (in der Variablen "bootargs") im -Boot-Kommando "bootcmd" (6) schrittweise zusammengesetzt: zunächst -werden die für Root-Filesystem über NFS erforderlichen Optionen ge- -setzt ("run nfsargs", vgl. (3)), dann die Netzwerkkonfiguration an- -gefügt ("run addip", vgl.
