The only difference concerns key naming. There are 4 -keys on TRAB: 1, 2, 3, 4. - -1) The "kbd" command provides information about the current state of - the keys. For example, - - TRAB # kbd - Keys: 1 0 1 0 - - means that keys 1 and 3 are pressed. The keyboard status is also - stored in the "keybd" environment variable. In this example we get - - keybd=1010 - -2) The "preboot" variable is set according to current environment - settings and keys pressed. This is an example: - - TRAB # setenv magic_keys XY - TRAB # setenv key_magicX 12 - TRAB # setenv key_cmdX echo ## Keys 1 + 2 pressed ##\;echo - TRAB # setenv key_magicY 13 - TRAB # setenv key_cmdY echo ## Keys 1 + 3 pressed ##\;echo - - Here "magic_keys=XY" means that the "key_magicX" and "key_magicY" - variables will be checked for a match. Each variable "key_magic*" - defines a set of keys. In the our example, if keys 1 and 3 are - pressed during reset, then "key_magicY" matches, so the "preboot" - variable will be set to the contents of "key_cmdY": - - preboot=echo ## Keys 1 + 3 pressed ##;echo - -3) The TRAB board has optional modem support. When a certain key - combination is pressed on the keyboard at power-on, the firmware - performs the necessary initialization of the modem and allows for - dial-in. The key combination is specified in the - "include/configs/trab.h" file. For example: - - #define CONFIG_MODEM_KEY_MAGIC "23" - - means that modem will be initialized if and only if both keys 2, 3 - are pressed. Note that the format of this string is similar to the - format of "key_magic*" environment variables described above. |
