3.3.1.1 Ignition On/Off

1. Turn on the system by ignition

For the cases of in-vehicle applications, an ignition signal is often used to turn on or shut down the system. When the system is in the OFF state and the ignition is turned ON, MCU will count down for ON_DELAY second(s); once it counts to zero, the system will be turned on immediately.

The MCU boot console is shown as below.

Note, the rework might be needed for the MCU UART console.

Change SW1 to HIGH and SW2 to LOW respectively, Ignition is enabled.

2. Shutdown the system by ignition

When the system is powered on and the ignition is turned off, the OFF_EVENT_DELAY will start to count down. During this stage, if the ignition is backed to ON, MCU will stop the countdown and reset the OFF_EVENT_DELAY value.

If OFF_EVENT_DELAY counts to zero, MCU will send an event (power button press) to the system and start to count down HARD_OFF_DELAY.

Note, NV idia will pop a "Power Off" dialog when entering the power off state.

3. Accidentally touched shutdown menu

When the user accidentally touches a button or shuts down in a short case, the OS will pop out a window and the system will start counting for 30s to shut down.

At this time, if the window is closed via the mouse, the system will consider the behavior mode of improper shutdown and start counting down for 180s to shut down.

Note, NV idia will pop a "Power Off" dialog when entering the power off state.

4. Power LED OFF behavior

When the user switches to any function, as long as the final path is related to the M7 Function, the green Power LED will light off. At this time, the user needs to manually turn the switch back to OFF, and the system will return to the System OFF stage then proceed to the power-on and power-off options that the user needs.

5. Low battery protection

To avoid draining out the car battery, low-battery protection is involved to ensure the car battery is able to start the vehicle. When the system is ON, MCU will monitor the car battery voltage. If the battery voltage is lower than a programmable threshold (LOW_THRESHOLD), MCU will go into LOW_DELAY stage and start to count down. During the stage of LOW_DELAY countdown, if battery voltage rises to above LOW_THRESHOLD, MCU will stop counting down and return to the System ON stage. If LOW_DELAY counts to zero, MCU will send an event (power button pressed) to notify the system and go into LOW_HARD_DELAY stage and start to count down. Once LOW_HARD_DELAY counts to zero, MCU will cut off the system power immediately to avoid draining out the car battery.

Figure 3.4 Ignition Disable

1. Turn on the system when ignition disabled

For the cases of in-vehicle applications, an ignition signal is often used to turn on or shut down the system. When the system is in an OFF state and the ignition is disabled, after the AC is ON, the system will be turned on.

The MCU boot console is shown as below.

2. Shutdown the system by power button

When the system is powered on and the power button is long-pressed, the system will be powered off immediately. Afterward, once the power button is pressed again, the system will boot up with the ATX mode. When the system is powered on and the power button is short-pressed, the OS will pop out a window and start counting for 30 seconds to shut down. After the system has shut down, once the power button is pressed again, the system will boot up with the ATX mode.

3. Low battery protection

To avoid draining out the car battery, low-battery protection is involved to ensure the car battery is able to start the vehicle. When the system is ON, MCU will monitor the car battery voltage. If the battery voltage is lower than a programmable threshold (LOW_THRESHOLD), MCU will go into LOW_DELAY stage and start to count down. Once LOW_DELAY counts to zero, MCU will cut off the system power immediately to avoid draining out the car battery. Afterward, once the power button is pressed, MCU will send an event (power button pressed) to notify the system to boot up.

3.4.3 Write the delay value to EEPROM

Please open test_init_delay_time.sh.

<h1 id="cd-tool">cd tool</h1>
<h1 id="sudo-chmod-x-test_init_delay_timesh">sudo chmod +x test_init_delay_time.sh</h1>
<h1 id="sudo-vim-test_init_delay_timesh">sudo vim test_init_delay_time.sh</h1>

We can adjust this value to meet our booting or shutdown time. For example, change "set-on-delay 10" to "set-on-delay 20". After the modification, as shown in the Figure 6, turn the AC OFF/ON of the machine again.

echo; echo "----[ init delay time ]----"
echo; ./vpmctrl set-low-delay 5; ./vpmctrl get-low-delay
echo; ./vpmctrl set-low-hard-delay 60; ./vpmctrl get-low-hard-delay
echo; ./vpmctrl set-on-delay 10; ./vpmctrl get-on-delay
echo; ./vpmctrl set-off-event-delay 10; ./vpmctrl get-off-event-delay
echo; ./vpmctrl set-hard-off-delay 180; ./vpmctrl get-hard-off-delay 

It's recommended to have a clear power cycle after the modification has been written to MCU.
