Powering Intelligence at the Edge

Secure Boot only allows digitally signed bootloaders and operating systems to start.

If the USB installer contains:

• Unsigned bootloaders
• Custom Linux distributions
• Modified Windows PE images

the system may block the boot process.

In such cases, try:

• Using a Secure Boot compatible installation image.
• Temporarily disabling Secure Boot.
• Verifying that the installation media was created correctly.

The BIOS version information can be viewed during system startup or from the BIOS Setup Utility, as shown in the screen below.

To help us investigate efficiently, please provide:

• Product Model
• Serial Number
• BIOS Version
• Operating System Version
• Problem Description
• Photos or Videos (if available)

The product model name and serial number can be found on the product label attached to the chassis.

Secure Boot and TPM (Trusted Platform Module) are different security technologies.

Secure Boot

• Protects the boot process.
• Verifies the authenticity of bootloaders and operating systems.

TPM

• Provides hardware-based security functions.
• Stores encryption keys and certificates securely.
• Supports features such as BitLocker and device attestation.

Many SINTRONES platforms support both Secure Boot and TPM 2.0 for enhanced system security.

Yes.

Most SINTRONES platforms support UEFI Secure Boot, which helps protect the system against unauthorized operating systems, bootloaders, and malware during the boot process.

Secure Boot can be enabled or disabled through the BIOS Setup Utility.

Note:

• Some third-party operating systems, drivers, or custom bootloaders may not be compatible with Secure Boot.
• Disabling Secure Boot may be required when installing certain Linux distributions or customized operating system images.

SINTRONES provides Vehicle Control Tools sample code to help developers quickly integrate vehicle-related functions into their applications.

The sample code demonstrates how to access and control platform features such as:

• Ignition (IGN) status monitoring
• UPS status monitoring
• Digital I/O (DIO) control
• CAN Bus communication
• MCU register access
• Other platform-specific vehicle control functions

Users can use the provided sample code as a reference and integrate the corresponding functions into their own software applications based on project requirements.

For detailed implementation examples and source code, please contact the SINTRONES technical support team.

The SINTRONES UPS function is integrated into the system and does not require an external UPS device.

When both the main DC input power (DC+) and the ignition signal (IGN) are removed, the system automatically enters UPS Mode and starts the configured UPS Delay Off Timer.

During the UPS Delay Off period:

• The system continues operating using the internal UPS battery.
• Applications can continue running normally.
• The operating system can perform data saving and graceful shutdown procedures.
• The remaining backup time depends on system power consumption, battery condition, and UPS configuration.

When the configured UPS Delay Off Timer expires, the system will automatically perform a safe shutdown and power off to prevent unexpected data loss.

Note:

• UPS Delay Off time can be configured through the BIOS, MCU utility, or platform-specific settings depending on the product model.
• The actual backup duration may vary based on system loading and battery capacity.
• It is recommended to configure a sufficient delay time to allow the operating system to complete its shutdown process safely.

Typical MCU functions include:

• Ignition Control
• UPS Delay OFF Timer
• DIO Control
• Power ON/OFF Delay Timer
• Hardware OFF Delay Time
  For further information, please contact the SINTRONES Technical Support Team.

The MCU firmware version can be queried through:

• MCU Utility
• Linux I2C commands
• BIOS Mainpage

depending on the platform model.
