Digi Embedded for Android provides a command line tool, mca_config_tool, to configure internal variables of the Micro Controller Assist (MCA).
You can use the following application options:
mca_config_tool --help mca_config_tool --factory_reset mca_config_tool --pwroff_boot_duration[=N] mca_config_tool --reset_delay[=N] mca_config_tool --boot_mode[=MODE]
The following table describes each command line option:
Command line option | Action |
---|---|
--help |
Print help message (the information on this table) |
--factory_reset |
Perform a NVRAM reset to factory default settings. |
--pwroff_boot_duration[=N] |
Get/set the time in ms that the PMIC_ON_REQUEST line is de-asserted during system boot (register PWROFF_BOOT_DURATION) |
--reset_delay[=N] |
Get/set the delay in ms that the MPU reset line will be asserted after the PMIC power-on event, at system boot |
--boot_mode[=MODE] |
Configure the SOM boot mode by selecting between ‘W4PK’ (wait for power key) or ‘BOP’ (boot on power). If W4PK is selected, the system doesn’t boot until the MCA PWR_IO line is asserted low. This line is commonly connected to the power button. If BOP is selected, the SOM automatically boots as soon as power is applied |
Get settings
You can read settings values from NVRAM. For example, to show the time that the MCA spends asserting the reset line, use the following command:
~# mca_config_tool --reset_delay Current Reset delay is 1 ms
Modify settings
You can modify settings and save the values to NVRAM. For example, to set a new value for the time that the MCA spends asserting the reset line, use the following command:
~# mca_config_tool --reset_delay=50 Configuration saved.
