release notes

Follow these steps to update your unit:
  • Select the UPDATE FIRMWARE menu option in the settings screen, which will put your unit into flashing mode
  • Click the blue connect button below
  • Select your RMP from the list of ports listed in the device window that pops up
  • Click "INSTALL RMPRO FIRMWARE" from the Device Dashboard window
  • Click "INSTALL" to confirm you want to flash your unit

The web-flash tool will then erase the flash on your RMP and re-flash it, and that's it, you're done!

IMPORTANT! Once complete your RMP will restart and you may get an error stating the serial port is not ready. That is simply because the serial port will change when the unit restarts. You can ignore this error and just close the dialogue.
