-The TRAB keyboard implementation is similar to that for LWMON and
-R360MPI boards. 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.
