Tastaturabfrage: |
||||
|
||||
Die Implementierung / Decodierung beruht auf den Angaben aus dem Do- |
||||
kument "PIC LWE-Tastatur" in der Fassung vom 9. 3. 2001, insbesonde- |
||||
re Tabelle 3 im Kapitel 4.3 Tastencodes. In U-Boot werden die vom |
||||
Keyboard-Controller gelesenen Daten hexadezimal codiert in der auto- |
||||
matisch angelegten Environment-Variablen "keybd" übergeben. Ist kei- |
||||
ne Taste gedrückt worden, steht dort: |
||||
|
||||
keybd=000000000000000000 |
||||
|
||||
Der decodierte Tastencode ("keybd") kann mit den "bootargs" an den |
||||
Linux-Kernel übergeben und dort z. 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. (4)), und schließlich die Systemconsole |
||||
definiert ("run addfb"). |
||||
|
||||
Dabei wird im Normalfall die Definition (5) verwendt; wurde aller- |
||||
dings beim Reset die entsprechende Taste gedrückt gehalten, so wird |
||||
diese Definition bei der Ausführung des in (2) definierten Kommandos |
||||
überschrieben, so daß Linux die Bootmeldungen auch über das Frame- |
||||
buffer-Device (=LCD-Display) ausgibt. |
||||
|
||||
Beachten Sie die Verdoppelung der '\'-Escapes in der Definition von |
||||
"key_cmd#" - diese ist erforderlich, weil der String _zweimal_ inter- |
||||
pretiert wird: das erste Mal bei der Eingabe von "key_cmd#", das |
||||
zweite Mal, wenn der String (als Inhalt von "preboot") ausgeführt |
||||
wird. |
