had a great flight with my octo yesterday without any problems. whenever i connect my pixhawk today, there is a weird sound beeping. it isnt reacting on anything i do. i then tried to connect to mission planner to figure out whats wrong but i cant connect via mavlink. it runs into timeout although mp recognizes the px4.
it sounds like this warning but going down on the last 3 extra beeps.
does anybody know what to do?
Hi Ben here is a link to the sounds that the various boards make and their meaning, yours means "New IO board firmware found(restart with safety button pushed to upload"
i know all these sounds but mine isnt there. the beginning of it sounds exactly like the one you say but the last tree beeps are deeper.
and the weird thing is that i havent done anything over night and i cant connect via mav link now. i havent connected the pixhawk neighter after the last flight yesterday nor the first time i tried to fly today. no computer was used, no telemetry. i just connected the full recharged battery packs and the pixhawk doesnt start as it should. so how can the px4 recognize a new i/o firmware if there was no connection yesterday or today?
Did you try and restart while holding the safety button down.
or try a reset and reinstall the firmware maybe.
it just occured as i tried to show the copter to some students. i did a reset on i/o and FMU. but no changes. didnt try the safety button. ill do so later and see what happens. its just very strange that it can find a new firmware without a connection to a computer and several flights in the last three days
Try to reformat the sdcard and reinsert it afterwards.
thanks Hugues and Martin
reformat didn`t help. pushig the button eighter. still not working
this is what happens when i power up pixhawk. the sound is different in the end. i also recognized that there is no light at the safety switch
This is weird and an undocumented sound, indeed. I guess you should send it back under warranty for an exchange, if you have tried to erase and reflash and the issue remains.
I contacted 3DR and we did a sensor testing procedure.
my FMU has no connection to the I/O controller so i had to ship it back to them.
thanks for your help Martin and Hugues.
I have the same werid sound.... what could be the issue? Any way to resolv eit?
Thanks... unforutnately I couldn connect to the board with all 3 steps. Either if I power the Pix from the Power Board or via USB keeping the switch pressed I get that weird sound....
but if I connect to the RC In also a backup 5 Volt power that the pix boots up normally and I get the heartbeat blue led from IO. Unfortunately it sill cannot connect and when I try in the Terminal I get this
Rebooting COM3 at 115200
Cant open serial port
mhh I tried another Pix... with this I cant connect either in the Terminal, while I can connect in standard mode
