The firmware programs SoC with LTE modem, which handles radio communication (OcuSync) and controls intelligent flight functions (obstacle avoidance). Location of this chip:
- in WM220, LC1860C SoC is on WM220 Core Board A
- in WM240, LC1860C SoC is on WM240 Core Board
- in other products, the location is unknown
The module contains programming of a SoC originally designed as main processor in mobile phones; here software-defined part of LTE modem is re-programmed to create OcuSync protocol instead. All stages of the OcuSync transmission are closed within one chip. Remaining processing power and camera interfaces are used to implement obstacle avoidance system (called APAS - Advanced Pilot Assistance System).
TODO
The IM*H module within FW update package is always encrypted, with AES, using platform-specific UFIE key.
Decrypted firmware is a JAR file, which when unzipped reveals typical Android partitions (normal, recovery, system, vendor), an a 2nd stage bootloader.
