Upgrading the System

Procedure

1. Install the Atlas 200 AI accelerator module on the PCB.
2. Log in to the OS of the Atlas 200 AI accelerator module and perform the following operations as the root user.
3. Use WinSCP to upload the target version software package A200-3000-Soc-FW-Vxxx.zip to any directory, for example, /opt/mini/.
4. Run the following command to go to the directory where the software package is stored, for example, /opt/mini/:

   cd /opt/mini

5. Run the following command to rename the package mini_developerkit.rar:

   mv A200-3000-Soc-FW-Vxxx.zip mini_developerkit.rar

6. Run the following command to decompress mini_developerkit.rar to obtain the upgrade script minirc_install_phase1.sh:

   Ensure that the partition has sufficient space for storing the decompressed package. If the space is insufficient, the upgrade will fail.

   unzip mini_developerkit.rar

7. Run the following command to copy the upgrade script minirc_install_phase1.sh to the directory where the target version software package is stored, for example, /opt/mini/:

   cp mini_developerkit/scripts/minirc_install_phase1.sh /opt/mini

8. Run the upgrade script.
   1. Run the following command to grant the execute permission on the minirc_install_phase1.sh file:

      chmod u+x minirc_install_phase1.sh

   2. Run the following command to start the upgrade script:

      setsid -w ./minirc_install_phase1.sh

9. Run the following command to restart the Atlas 200 AI accelerator module:

   reboot

10. (Optional) After the Atlas 200 AI accelerator module is started, query the Atlas 200 AI accelerator module version number.
    1. Run the following command to switch to the firmware directory:

       cd /var/davinci/firmware/

    2. Run the following command to check the version information. If the version information is the same as that of the software package, the upgrade is successful.

       ./upgrade-tool --device_index -1 --component -1 --version

11. (Optional) Check the PCB version number after upgrade.

    Run the following command to view the content of the sys_version.conf file:

    cat /var/davinci/sys_version.conf
