Many Pixhawk 2.4.8 clones use an early STM32F427 chip revision that limits usable flash memory to 1 MB . This can prevent newer, larger firmware versions from loading unless you use specific "slim" builds.

Excellent wind handling, massive documentation, robust community support, and highly reliable fail-safes.

Unlike modern firmware, 248 requires a 3D fix (not 3D dGPS) and at least 6 satellites . Wait longer or adjust GPS_HDOP_GOOD to 2.0 (default is 1.6). The Pixhawk 2
