Kernel release: 5.15.0-1029-mtk

Installation and Post-Installation

1. Download the Ubuntu OS image (Desktop or Server) of your choice. The following steps apply to both Ubuntu Desktop and Ubuntu Server. https://ubuntu.com/download/mediatek-genio

2. Download the boot firmware for your SOM-SMARC-Genio700 from our latest release.

3. Extract the Ubuntu image first, and then extract the boot firmware into the same directory. On Ubuntu host PC this can be done with the following commands:

   Code Block
   language bash
   tar -xvf {UBUNTU_IMAGE}.tar.xz tar --strip-components=1 -xvf {BOOT_FIRMWARE}.tar.gz -C {UBUNTU_IMAGE}/ cd baoshan-{UBUNTU_IMAGE}

4. The resulting image directory should contain at least these files:

   Code Block
   $ ls bl2.img bootassets.vfat fip.bin firmware.vfat lk.bin u-boot-initial-env ubuntu.img ubuntu.json

5. Check the following lines in the u-boot-initial-env file. They are responsible device tree overlays which will be applied. You can remove or add overlays from the list.

   Code Block
   conf ... list_dtbo= gpu-mali.dtbo video.dtbo apusys.dtbo

6. You can also set the MAC address at the boot time, which will be saved in the bootloader config. You can do so by adding a new line to u-boot-initial-env file:

   Code Block
   ethaddr=00:55:7b:b5:7d:f7

7. Connect the Baseboard with SOM-SMARC-Genio700 module to PC. Open a terminal application on your host PC and connect to the serial device (converter name). Make sure you set the following parameters on your terminal application:

   • baud rate: 921600

   • 8-bit

   • Party bit: 1

   • No flow control

8. Launch a command line prompt on your host PC.
   First change directory(cd) to the image directory, and run genio-flash:

   Code Block
   cd {UBUNTU_IMAGE} genio-flash

   The tool should have the following output:

   Code Block
   genio-flash AIoT Tools: v1.3.4 Ubuntu Image: ... Looking for MediaTek SoC matching USB device 0e8d:0003 ...

   The line Looking for MediaTek SoC matching USB device 0e8d:0003 shows that genio-flash tool is waiting for the board to be reset into download mode to start the flash programming procedure.

9. Set the board into download mode
   Describe the procedure here

10. The flash tool should continue with the following log output, which shows the progress of erasing the onboard storage and writing image content to the storage:
