Known DUML commands, to be sent over the virtual USB COM port (or TCP for devices without one):
Enter Flight Log mode (Verified on Mavic with .700 FW)
55 0D 04 33 2A C3 44 31 40 03 39 1F 79 55 0E 04 66 2A 00 0B 34 40 00 01 05 81 4D
Upon issuing these 2 commands the Flight Controller's SD card containing the detailed .DAT logs is mounted (read-only) on the host computer. The directory is also mounted (read-only) on the aircraft's filesystem at /ftp/flyctrl. It is visible on the FTP server, but pulling files through FTP does not work since the read-only mount prevents creation of the temporary encrypted file by DJI's modified busybox binary. The flight log card can be remounted rw using:
mount -o remount,rw /ftp/flyctrl
When uploading files to the card either through adb or FTP it seems the device will cause an IO error after about 1GB of transfer volume, requiring a reboot. Files can't be written through USB.
