Configure Intel® GMSL SerDes ACPI Devices#

To enable multiple GMSL cameras, for the same or different vendors, define the MIPI camera ACPI device in UEFI/BIOS settings.

  1. Review Intel®-enabled GMSL2 camera modules with their corresponding ACPI device custom HIDs:

  2. Review the GMSL Add-in-Card Design Overview, if not already done.

    Refer to each tab below to understand the distinct ACPI camera device configuration tables for ODM hardware.

    The Advantech® GMSL Input Module Card for AFE-R360 series and ASR-A502 series may provide up to 6x GMSL camera interfaces (FAKRA universal type).

    Attention: For the time being, each GMSL2 aggregated-link deserializer, for example MAX9296A, on the same I2C channel must set an identical Custom HID and Camera module label tuple matching the GMSL2 serializer and camera sensor device type.

    For the Advantech® GMSL Input Module Card for AFE-R360 series, the I2C1-channel aggregated-link deserializer at I2C device 0x48 can set the Custom HID, for example INTC10CD, and Camera module label, for example d4xx, tuple for both GMSL camera suffixes a and g, while the other aggregated-link deserializer at I2C device 0x4a can use a different Custom HID, for example INTC1031, and Camera module label, for example isx031, tuple on GMSL camera suffixes e and k.

    The SEAVO® Embedded Computer HB03 UEFI BIOS Version: S1132C1133A11 allows an admin user to configure up to 4x GMSL2 camera interfaces (FAKRA universal type).

    Note: On Axiomtek ROBOX500, the 4x D3CMCXXX camera ACPI configuration achieved by PPR Unit=1 requires setting Device0 for the GMSL2 aggregated-link deserializer I2C address, for example MAX9296A, and Device2 for the sensor I2C address, for example ISX031.

    Below is an ACPI device configuration example for four GMSL2 camera modules from D3 Embedded Discovery PRO:
