Pixhawk 2.1 BRD_TYPE Error

Hey guys,

A customer of mine suddenly started receiving the following error on a Pixhawk 2.1-equipped quadcopter. It also constantly emits the startup tone over and over again, and becomes very hot to the touch. Some details:

  • He’s using a custom firmware variant apparently based on AC3.5-rc8 but with some expanded CAN functionality. We checked to ensure the board target temp was set to 60. I’ve attached the custom firmware file.

  • The copter was calibrated and flown successfully this morning with no behavior issues. The error appeared while sitting on the bench

  • The Pixhawk doesn’t power up at all when the aircraft is powered by a battery. Only when connected directly via USB. Checked power connections; they’re fine.

Any thoughts? This system is identical to many I’ve built and delivered previously aside from the custom firmware, but I’ve never seen this particular error before. Will supply logs once I look through them and figure out which of them is relevant.
