Our data acquisition methodology is based on the Chip-Off and Chip-On technique.
First, we dismantle the drone to reveal motherboard, then we try locating the flash memory. Once we have found the flash memory, identify the model and type followed by reading the data sheet of identified memory chip. By referencing the correct datasheet of the flash memory is important as identify the pins on the chip, these will be discuss in the next slide.
Then we try to read the data directly from the chip by connecting to a memory chip reader. If that is not possible, we do track the circuit using 2D/3D X-Ray to identify connection points to read the memory then we connect in-system programming to the points to read data off the chip.
