Setting the Power Consumption Level in Main Processor or Coprocessor Mode

Procedure

1. Decompress the Atlas200_SoC_SDK.zip package to obtain the Hashrate_package.zip package. For details, see Downloading Software Packages.
2. Decompress the Hashrate_package.zip package to obtain the hashrate configuration files.

   The nve_low.bin, nve_middle.bin, nve_high.bin, and nve_full.bin files in the Hashrate_package.zip package correspond to the lowest level, second lowest level, second highest level, and the highest level, respectively.

3. Burn the nve_XX.bin file to change the power consumption level.
   1. Run the following command to go to the /var/davinci/firmware directory:

      cd /var/davinci/firmware

   2. Run the following command to switch to user root:

      sudo root

   3. Run the following command to burn the nve_XX.bin file:

      ./upgrade-tool --device_index -1 --component nve --path <path/to/nve.bin>

      For example, run the following command to change the power consumption to the lowest level:

      ./upgrade-tool --device_index -1 --component nve --path ./nve_low.bin

      If the following information is displayed, the burning is successful.

      root@davinci-mini:/var/davinci/firmware# ./upgrade-tool --device_index -1 --component nve --path ./nve_low.bin
              {"device": 0, "succeed"}
      root@davinci-mini:/var/davinci/firmware#

4. Run the following command to reboot the system for the modification to take effect:

   reboot

5. Check whether the hashrate configuration file has taken effect.
   1. Go to the /var/davinci/firmware directory.

      cd /var/davinci/firmware

   2. Switch to user root.

      sudo root

   3. Check whether the hashrate configuration file has taken effect.

      ./opsread-tool

      The hashrate configuration file has taken effect if the following information is displayed:

      root@davinci-mini:/var/davinci/firmware# ./opsread-tool
      low
      root@davinci-mini:/var/davinci/firmware#
