SOLVED:Cant flash again "Failed to get init ACK from device"

Postby Kosmonaut » Fri Jul 05, 2013 1:27 am

Hi AQler,

after setting up my AQ - flashing with FW 6.6.1 rev2 it first looked good but when it comes to try the first flying i have some problems with spinning some of the motors. Only the front left (Quad X) is spinng up then with more throttle the left back Motor spins up too, but both right motors does not spin. i configured the mixing table custom to use the Port 3 (left front), 10 (right front), 8 (right back) and 1 (left back) to keep the cables short.

After long trys in differnt ways i decided to flash the AQ new and now i always get the well know Message:

"Failed to get init ACK from device"

Com port is right, jumper is set, Flyduino FTDI connected right (new version).
I can connect to the AQ in non bootloader mode, i see my rc controls working fine, i can arm and disarm, see the horizon moving right - so connection seems to be fine - but if i try to write any change to the aq i get the warning:

"possible problem(s) exist:

Do you wish to ignore this and continue saving?"

Additional i cant see the Version of the AQ FW in QGroundstation 1.3B or 1.2.1.

My Testsystem (QuadX) is flashed with FW 6.6.1 rev 2 and i use blheli ESCs with fully damped Mode (HK-10) with Suppo 2208 and RC is via PPM with old Graupner MX16 Hott and Thomas Scherrer LRS.

I think there is something wrong with the FW on the AQ but i cant flash it - any Advice is highly appreciated.

Hi again,

i get some progress - when i choose (in non bootloader mode and coonected) "Onboard Parameters" and then klick "read" the parameters are downloaded. When i did this the second time i can now see the AQ FW Version in QGround:
AutoQuad FW v. 6.6.1 r165 b1036 HW v 6r2

Then i looked what the settings look like - PPM and RC Channels were right, but in "Mixing & Output" it was set to an very confusing Octo, i never choose an Octo and after loading my QuadX settings i can write to the AQ, so the seqond part of my problems is now gone :-).

But the flashing Problem is still there...

Good morning!

The problem is solved - very stupid reason: the jumper for flashing was set but a little to the side so that it has no connction to the pins but looks fine and as i have moved it i thought it must be ok. maybe i use a other jumper which has not this mechanical problem

Now first flight is m< daily target ... :-)
