README.kbd
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.
