Hello everyone, does anybody know the solution of the internal error 0x800?
Solution: Take out your I2C connection if gps is connected. I just using the m8n gps and took out the i2c connection. Then reflash your pixhawk as different than your build, after you built your device as different than your device then reflash your device firmware. (I were using rover 4.0.0 and I reflashed the plane 4.0.9 and then reflashed rover firmware again.) While doing that do not connect your i2c connection. Then unplugged your flight controller. Took out its sd card and format it as fat32. Plug your sd card that you formatted as fat32. Then plug your flight controller. Now you can plug i2c cable of gps and calibrate it from the beginning. I solve this problem as I wrote.
