Command Description
io-pullup-f <state>
Enables or disable the internal pull-up resistors of the
GPIO pins in port f. It is required to issue a commit after
the command for the parameters to be persistent across
restarts or power cycles.
This command requires a restart or power cycle to be
applied.
For a pin to be an input it must be set to 1, for output it
must be set to 0.
The <state> for the pins is the decimal value of the 8 bit
binary value that represents the desired state of the 8
GPIO in the port, e.g. 11111111 = 255 (all pins input),
11110000
= 240 (7,6,5,4 = Input, 3,2,1,0 = output).
Requires that the primary UART and LED signals have been
disabled.
io-pullup-g <state>
Enables or disable the internal pull-up resistors of the
GPIO pins in port g. It is required to issue a commit after
the command for the parameters to be persistent across
restarts or power cycles.
This command requires a restart or power cycle to be
applied.
For a pin to be an input it must be set to 1, for output it
must be set to 0. Note that pin 3,4 and 5 are ignored
The <state> for the pins is the decimal value of the 8 bit
binary value that represents the desired state of the 8
GPIO in the port, e.g. 11111111 = 255 (all pins input),
11110000
= 240 (7, 6= Input; 2, 1, 0 = output; 5, 4, 3 =
ignored).
Requires that the secondary UART has been disabled.
conn-led <state>
Enables or disables the CONN LED to allow the pin to be
used as a GPIO.
The <state> can be set as either enable or disable.
post-led <state>
Enables or disables the POST LED to allow the pin to be
used as a GPIO.
The <state> can be set as either enable or disable.
rf-link-led <state>
Enables or disables the RF_LINK LED to allow the pin to be
used as a GPIO.
The <state> can be set as either enable or disable.
wln-cfg-led <state>
Enables or disables the WLN_CFG LED to allow the pin to
be used as a GPIO.
The <state> can be set as either enable or disable.
serial-port-pX <state>
Enables or disables the primary serial port (UART1).
The <state> can be set as either enable or disable.
If your system uses pull-up resistors on the circuit assembly then it is not
necessary to enable the internal pull-up resistors available on the device server,
to do this issue io-pullup-f disable or io-pullup-g disable and
commit the parameter.
