check BRD_TYPE:Failed to init CubeBlack -sensor

hello… this is my first contribution here, i’m a beginner in pixhawk,… I have a pixhawk 2.4.8 which was working fine, but yesterday, I tried to connect it to the laptop it refuses to arm and gived me the message:
check BRD_TYPE:Failed to init CubeBlack -sensor
and it didn’t give anysound and the main light is not lighting.
when I connect it to the battery, the main light gives a solid red without any sound.
may anyone help me please?

Looks like you loaded the wrong firmware onto it.
The fake Pixhawks need fmuv2 firmware
