@Eric-Katzfey Yes, I would agree. So what is the path I need to take to fix these issues? The entire setup consists of a Modal AI FCv2, a Modal AI FPV 4-in-1 ESC (over UART), a Mateksys SAM-M10Q into the "J10" port, a Spektrum FPV Racing Serial Receiver into the "J12" port, an RF Design 900x US Telemetry radio into the "J1" port, a USB to serial adapter (for connection to QGROUNDCONTROL) into the "J3" port, and I am powering my VTX system from the 5V and Ground out of the "J7" PWM port. There is nothing in my system that should be causing interference with the barometer, especially if the barometer is over I2C, because I am connected to all my other basic components via serial connections.

@Eric-Katzfey Yes, that is what appears to be happening. However I cannot properly isolate the FCv2 because other errors are present in QGroundControl due to the other missing components when trying to run the board in isolation. (GPS errors, RC Input Errors, etc.)

@Eric-Katzfey I could not get the barometer issues to show while strictly isolating the flight core v2, but I also have another FCv2 unit that I just completed assembling... after several hours of intermittent ESC connection issues (VOXL FPV ESC) the Baro 0 Missing error started displaying on the second flight core unit as well. Please advise.

@Eric-Katzfey Hi Eric, I believe I solved the Magnetometer sensor failure issues. Extreme interference from my radio transmitter was causing issues. I swapped it out to a different radio and that issue is no longer happening. I am still getting barometer issues though. It seems as if every other time I boot the drone on the barometer says its missing. Usually a reboot will solve this, but even when it isn't missing, the barometer seems to be having issues. I am getting close to 5ft in elevation variance when in Altitude and Position flight modes. Even when the gps is disconnected I am still getting these errors. Could it be a faulty or damaged flight controller?

I am getting errors while trying to set up my drone.

System:
Flight Core V2 Flight Controller running PX4 (Latest)
VOXL FPV 4-in-1 ESC
Mateksys SAM-M10Q GPS

Issues:
I am getting a persistent "Magnetometer sensor #0 failure: Timeout" on QGroundControl. Does the FC V2 have it's own magnetometer? Is the issue related to the onboard mag or the M10Q GPS I am trying to use? Upon rebooting, I will usually get the same error, but sometimes I get a "found 0 compass (required 1)" error.

I am also getting a "Barometer 0 Missing" error, but not consistently, sometimes a reboot will clear that error, sometimes it will not.

Any help in getting the barometer and gps properly set up would be greatly appreciated.
