3.1. Preparation#

3.1.1. Prerequisites#

Prepare the following hardware.

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 v7 image, please follow the below instruction.

  1. Download the image by using

wget https://swdownloads.analog.com/cse/gmsl/10G/v2_24/gmsl-10g-v7.tar.xz.gpg`

  1. Decrypt the gpg file by using gpg command.

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

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

Extract the image file

tar Jxvf ./gmsl-10G-v6.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 https://swdownloads.analog.com/cse/gmsl/10G/v2_24/gmsl-10g-v7.tar.xz.gpg.

  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.

3.1.3.3. (Optional) Using the C2 cameras#

Caution

  • This setting is only required in case you connect with the C2 cameras.

  • This procedure needs to be done when the SD card is mounted on the host PC.

By default, the image file is set to work with C1 cameras. To use the C2 cameras, you need to switch the device-tree file (dtb) file.

In order to do so, please copy the dtb file for C2 cameras to the root directory of bootfs, i.e.,

cp /media/ubuntu/bootfs/boot_files_v7/imx490/system.dtb  /media/ubuntu/bootfs/

(Assuming that the SD card is mounted at /mnt/ubuntu)

Then, please follow the following steps.

3.1.4. Hardware connection and setup#

../../_images/board_front.jpg

../../_images/board_back.jpg

Fig. 3.2 Back side of the board#

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

    • In case you connect 4 cameras, you can connect either P1 or P2 port.

    • In case you connect 8 cameras, please connect the Fakra cable to both P1 and P2 ports.

  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.
