Regulatory and ethical notes

• Ensure compliance with local UAV regulations for indoor/outdoor use, data capture, and safety.
• Obtain consent before recording others; privacy and ethical capture practices are important.
• Design for fail-safe behavior to minimize injury or property damage in case of malfunction.

4.1 Loading in Ghidra / IDA

Load the binary as raw ARM Thumb (little-endian, base address 0x00000000). The reset vector at 0x00000004 points to 0x00000101 (Thumb mode). Entry point reveals standard peripheral initializations: p1flyingring

• GPIO setup for an LED and a PWM pin (ring coil driver)
• ADC read from a Hall effect sensor (measuring ring position)
• UART at 115200 baud (debug output)

3. Initial Analysis

Running file on the binary reveals:
