BIOS/UEFI Configuration

Activate eMMC

To activate or deactivate eMMC Support apply the following settings:

1. Boot the system into the BIOS menu
2. Set up 'SCS/SCC Configuration' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > RC Advanced Menu > PCH-IO Configuration > SCS Configuration > eMMC 5.1 Controller = <Enabled>

3. Press <F10> to save the settings and reboot the system

Toggle module configuration between GPIO and SD card

The module can be configured either on GPIOs or on SD card. The same pins are used for both functions.
Only one function can be used at a time.

Activate SD-Card:

1. Boot the system into the BIOS menu
2. Set up 'SD-Card Controller' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > RC Advanced Menu > PCH-IO Configuration > SCS Configuration > eMMC 5.1 Controller = <Enabled>
 BIOS Frontpage > Setup Utility > Advanced (Tab) > RC Advanced Menu > PCH-IO Configuration > SCS Configuration > SDCard 3.0 Controller = <Enabled>

3. Set up 'GPIO/SD-Card Configuration' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > SIO TQMx86 > GPIO/SD-Card configuration = <SD-Card Interface>

4. Press <F10> to save the settings and reboot the system

Activate GPIOs:

1. Boot the system into the BIOS menu
2. Set up 'SD-Card Controller' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > RC Advanced Menu > PCH-IO Configuration > SCS Configuration > SDCard 3.0 Controller = <Disabled>

3. Set up 'GPIO/SD-Card Configuration' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > SIO TQMx86 > GPIO/SD-Card configuration = <GPIO Interface>

4. Press <F10> to save the settings and reboot the system

Enable console redirection (Serial)

To activate or deactivate console redirection apply the following settings:

1. Boot the system into the BIOS menu
2. Set up 'Console Redirection' option in the BIOS Menu accordingly:

 BIOS Frontpage > Setup Utility > Advanced (Tab) > Console Redirection > Console Serial Redirect = <Enabled>

3. Select and activate the desired UART port: 

 COMx > PortEnable = <Enabled>

Press <F10> to save the settings and reboot the system

Now the UEFI interface will be printed on the desired port with the Serial Port settings.

Reset UEFI Settings to Default

There are several ways to reset the UEFI firmware settings to the default values.

Important

The UEFI settings are stored in the SPI flash and no longer in the CMOS memory. Removing the buffer battery does not reset the settings.

Option 1: Press F9

The UEFI settings can be reset by pressing F9 in the UEFI. You have to be in the Setup Utility Page to use this function.

To reset the settings without the display, proceed as follows:

  1. hold ESC on the keyboard to enter UEFI (about 1min. to be safe)
  2. Press the Down key at least 5 times
  3. Press return to open the Setup utility
  4. Press F9 and then press Return to load setup defaults
  5. Press F10 and then Return again to save the settings and restart

Option 2: Update the UEFI Firmware

When updating the UEFI firmware, the firmware defaults are loaded and all changes to the settings are lost.
Installing the same firmware resets these settings (e.g. UEFI update under Windows).

Option 3: Reset via RESET button

Our modules provide a function that allows to reset the UEFI to default values in case of emergency.
For this, the reset button must be pressed three times within one second.
If the module LED blinks red for a short time the reset to defaults was successful.
