Troubleshooting - maxct/paparazzi GitHub Wiki

Here we describe some problems we've faced and ways to solve them.

###1. USB number might be wrong Sometimes the USB number of the Telemetry is not 0. Make sure the right number was allocated by the OS or change the USB port in paparazzi ###2. Cleaning and Building in Paparazzi Center after changes in XML After any changes in XML files for some copter (flight plans, telemetry, etc.) everything have to be cleaned and built again in Paparazzi Center for this copter. But it isn't necessary to do any changes with other copter(including uploading). ###3. make paparazzi after some md5 message If message about some problems with md5 sum appears in Paparazzi center, Paparazzi have to be closed and made again. ###4. Repository has to be updated

###5. Suicide bug Suicide bug is unstable behavior of copter just after the start. Copter doesn't start directly up, but in some random direction and crashes within a few seconds. To prevent such behavior one should wait for a few seconds after plug in battery. Copter needs this time for inner stabilization. To be sure, that stabilization is over, one should check speed of blinking of LED indicator in center of the copter. It should blink very slowly.
###6. We cant switch to default (flightplan) for 3_01 This bug appears when we were trying to switch to default part of flightplan from Paparazzi center, when battery have already plugged in. This problem appeared first time after we've started to use new telemetry. But with 3_02 everything is correct, furthermore it works much better than with previous telemetry.
