Updating your firmware

Necessary updates occasionally become available for the Energy Probe firmware.

Follow these instructions to update your firmware:


  1. Detach the Energy Probe probes and ground from the target.
  2. Plug the Energy Probe into a USB port on your Windows host machine.
    Because of a limitation with the USB bootloader from the MCU vendor, updating firmware on a Linux host is not supported.
  3. To enable firmware programming mode, insert a paperclip into the small hole on the top near the LED.
  4. Press and hold down the button for three seconds.
  5. Wait for the LED to turn red, and then off. Firmware programming mode is now active.
  6. When the drive folder opens, delete the firmware.bin file. This file is a placeholder.
  7. Drag and drop the new emeter_firmware.bin file onto the drive folder. This file is located in DS-5_install_directory/sw/streamline/energy_meter/energy_probe/.
  8. Safely remove the Energy Probe drive from the host machine using the Windows Safely Remove Hardware icon.
  9. Unplug the Energy Probe from the host machine.
  10. Wait for one second and plug it back in.
