Flashing

Below are the known ways to re-flash the firmware. Some of the flashing methods may not be listed here.

By official package in camera

The official way of flashing the firmware is by inserting an SD-card with firmware package file into the drone camera. The camera will extract modules from the package and distribute them to proper target components. It requires the firmware in bin form to exist in root directory of the SD-card.

In order for the firmware to be accepted:

  • it cannot be compressed on the SD-card
  • no newer firmware should exist on the card
  • the firmware must have original file name, specific to the product
  • the firmware must match the product being updated
  • the new firmware needs to be newer than current, or current needs to allow rollback to the target version
  • if a proper FW_DEBUG file (ie. P3X_FW_DEBUG for P3X) exists in the root directory of SD-card, the version checking rules above does not apply

After the upgrade, two logs will be created on the SD-card. The more verbose log will be in a MISC/LOG folder which has the hidden attribute set. It is best to check that log for a result information.

By firmware module in camera

The camera can also upgrade specific modules of the drone if properly named files are found on the SD-card. The firmware module file needs to be unencrypted - flashing an encrypted firmware this way will cause the updated device to crash during startup, and the only way to bring it back to life will be to hook to it directly and flash it using a hardware programmer stick.

The proper file name for P3XW is "PMVOM4Fw3.bin". For P3X and current firmware lower than P3X_FW_V01.05.0030, or P3S and current firmware lower than P3S_FW_V01.04.0010 the name is "MVOM4Fw.bin". For newer current firmware version, the accepted file name in P3X and P3S is "PMVOM4Fw3.bin".

After the upgrade, log files will be created on SD-card, similar to the method with package.
