Boot and Recovery Environment for Embedded Devices (BREED) is A multi-task bootloader with real-time firmware upgrading progress.
Because some official upgrade firmware comes with a bootloader, if you upgrade from the official firmware Web, it will cause Breed to be overwritten. When Breed flashes the firmware, it automatically removes the bootloader that comes with the firmware, so it can prevent Breed from being overwritten.
After updating the AR / QCA chip from U-Boot to Breed, please remember to check whether the MAC address is valid. If it is all FF, please modify it yourself! !!
