Crazyflie Startup melody played twice

[jakestmart]

Hi,

I currently have three crazyflies. I have recently just flashed all three the Crazyflie 1.0 using the latest firmware from: https://github.com/bitcraze/crazyflie-firmware

1 out of the 3 starts up fine and only makes the 'start-up' melody once. The 2/3 play the sound 'start-up' melody twice, about 1 second apart.

Where I had:

1. cd directory of frimware
2. make PLATFORM=CF1
3. cload PLATFORM=CF1

It updates the firmware fine, and I am able to connect to the crazyflie via the client.

• Plays start up melody twice
• When I add thrust there is no response

EDIT: This is what I have printed from the console tab:
IMU: MPU6050 I2C connection [OK].
IMU: HMC5883 I2C connection [OK].
IMU: MS5611 I2C connection [OK].
MPU6050: Self test [OK].
HMC5883L: Self test [OK].
MS5611: Self test [OK].
SYS: The system resumed after watchdog timeout [WARNING]

Has it got to do the with watchdog timeout?

Hi!

Yes, the watchdog has timed out, which in turn resets the processor. When the Crazyflie restarts it detects that it is recovering from a watchdog timeout, fails the self test and prints "SYS: The system resumed after watchdog timeout [WARNING]". The second start-up melody is played when it restarts.

Which version are you running? Could you please paste the full console log? There is a line at the top (saying something similar to "SYS: Build 10:d5eb851c07b0 (2015.08.1-10) CLEAN") that shows which version you are running.

Hi,

I have also flashed it with the VM 0.6. When i try connect via the cfclient I get the error:
"Dongle Communication error (ackStatus == None)"

this is the output from my console log below.

Hi!

We currently have some problems related to task priorities, interrupts, usb and i2c that we are working on (#72, #69) and your problems are most likely a duplicate of one of them. These problems became visible when we added the watchdog recently (fast fail for the win!).

What I might find a bit surprising is that you see these problems on 2 out of 3 Crazyflies.

The best workaround for you is probably to build the firmware in DEBUG mode, since that will turn off the watchdog
make clean
make PLATFORM=CF1 DEBUG=1

By the way, your problem with the VM is probably because the VM is not configured to use the USB for the crzyradio. See the "configuration" section of https://wiki.bitcraze.io/projects:virtualmachine:index

Closing this issue as duplicate.

I am having this issue still.

[krichardsson]

Which firmware version are you using?

[dajinchu]

All versions after 2015.1 (Crazyflie 1.0)

[krichardsson]

Is it still working on one of your Crazyflies but not the other 2? Is it always the same CF(s) that fail or does it work from time to time?

[dajinchu]

I am not OP of this issue.

[ataffanel]

Have you tried with the latest version from the repos?

So, This seems to actually be the issue #105. I reopened it and lets continue the discussion there.
