    See also

    How much host performance is needed to receive the image from GMSL2-10GbE conversion module?

  • 1 x SFP+ Ethernet cable or SFP to RJ-45 converter

    • SFP to RJ-45 converter: SFP-10G-T-S or SFP-10G-T-X

  • AC Adapter

    • Supply voltage: 10V < V < 48V

    • DC Jack: 5.5x2.5mm

Caution

Make sure the Host computer you use has 10Gb ethernet card/port. Otherwise, consider using an adapter, such as a Thunderbolt-10Gb Ethernet adapter.

This system may work with the other host operating system, such as Windows environment, but not supported by TIER IV yet.

3.1.2. Preparing the SD card image (with Linux environment)#

Firstly, you need to download the image file.

To download the v9 image, please follow the below instruction.

  1. Download the image by using

wget https://swdownloads.analog.com/cse/gmsl/10G/v2_24/gmsl-10g-v9.tar.xz.gpg

  1. Decrypt the gpg file by using gpg command.

gpg --output gmsl-10g-v9.tar.xz --decrypt gmsl-10g-v9.tar.xz.gpg

  1. The system will ask the passphrase. Please contact to TIER IV for the passphrase.

  2. after decrypting the gpg file, please proceed to the next step.

Extract the image file

tar Jxvf ./gmsl-10g-v9.tar.xz

Connect the SD card to the computer. Then identify the SD card using lsblk command. The result will look like the below.

In this case, the SD card is /dev/sda.

Then burn the image file to the SD card (Please change the name-of-the-image.img and /dev/xxx upon your environment). This process may take several minutes.

sudo dd if=name-of-the-image.img of=/dev/xxx bs=4M status=progress
sync

After burning the image file, please proceed to the next step.

3.1.3. Preparing the SD card image (with Windows environment)#

3.1.3.1. Download the image and extract it#

  1. Download the image from the URI as described in the Linux section

  2. decrypt the file by using gpg. Please contact to TIER IV for the passphrase.

  3. Extract the image, for instance, by using Zip Extractor

3.1.3.2. Burning the image#

You can use various software, such as Etcher or Raspberry pi Imager to burn the image file to the SD card. Please download & install your preferred SW.

In this document, we take Raspberry pi Imager as a example.

  1. Open Raspberry pi Imager

  2. Select CHOOSE OS -> Use custom

  3. Select Extracted image file (***.img).

  4. Select Target SD card by selecting CHOOSE STORAGE

  5. Click NEXT then start the burning.

3.1.4. Hardware connection and setup#

  1. Connect the Fakra cable to the GMSL port. You need to use mini-Fakra jack cable.

    Attention

    There are some points to note about connecting the camera. Please check this page for details.

  2. Connect the Cameras to the Fakra cable.

  3. Connect the ethernet cable to the ethernet port.

    Caution

    You need to use SFP+ ethernet cable or SFP to RJ45 converter.

  4. (Optional) Connect mini-USB cable to the serial port.

  5. Insert the SD card into the SD card slot.

  6. Power on the board by inserting the power plug.
