Bug report

Issue details Please describe the problem When configuring a parachute, if both "parachute enable" and "parachute release" are set on RC channel options, on the next reboot. GCS will not be able to fully read all parameters. Mission Planner, APM Planner 2, and QGroundControl all fail to read all parameters, hanging on VISO_ORIENT. This happens regardless of connecting via USB or telemetry modem. If I remove "parachute enable" from the RCx channel option, on reboot all parameters read fine again.

Here's the relevant parameters I used CHUTE_ALT_MIN 3 CHUTE_DELAY_MS 300 CHUTE_ENABLED 1 CHUTE_SERVO_OFF 1050 CHUTE_SERVO_ON 1950 CHUTE_TYPE 10

SERVO10_FUNCTION 27 SERVO10_MAX 2000 SERVO10_MIN 1000 SERVO10_REVERSED 0 SERVO10_TRIM 1500

CH10_OPT 21 (Chute enable: if this is set params don't load) CH11_OPT 22 (Chute release)

Version What version was the issue encountered with Copter 3.5.7 Stable Mission Planner 1.3.58 Winx64 APM Planner 2.0.24 Winx64 QGroundControl 3.2.4 Winx64 Platform [ ] All [ ] AntennaTracker [x] Copter [ ] Plane [ ] Rover [ ] Submarine

Airframe type What type of airframe (flying wing, glider, hex, Y6, octa etc) OctaQuad Hardware type What autopilot hardware was used? (Pixhawk, Cube, Pixracer, Navio2, etc) Pixhawk 2.1 FrSky R-X8R connected via S.Bus Logs Please provide a link to any relevant logs that show the issue

Is this issue still open???!

Can confirm this issue still exists in 3.6.11.

Disabling "Parachute Enable" from a CHxx_OPT Param "solves" the problem.

@JacksonUAS, it's still open and it doesn't look like anyone has looked into it yet so I expect the issue is still there in Copter-4.0.0 as well. Hopefully we will get to it.

The CH10_OPT param causing the issue is gone in 4.1, I have been playing with parachutes recently and never hit this, so I'm going to close.
