This file documents GPL violation by SZ DJI Technology Co., Ltd.. On 2016-09-28, the company released a new product - Mavic Pro. This drone uses Atmel ATSAME70Q21 micro-controller as the Flight Control unit. It looks like some shortcuts were taken while porting the FC code to the new MCU. Low-level driver code for MMC and SD memory was copied from U-boot, which is an amazing bootloader based on GNU General Public License. Here you will find proof of the violation, and the means to reproduce the findings.
