PIXHAWK ISSUE NEED SUPPORT

Posted by Jeff P on December 29, 2013 at 11:03am

Hoping someone can help, I have a lot of knowledge of APM 2.0, 2.5, 2.6 etc.......so do not need the basics.

Never had a problem with APM.  Received my Pixhawk yesterday.  Please note I have tried this with the new APM planner and Mission Planner after the most recent update.  This is the issue.

I can connect to the unit via USB ONLY to load the firmware.  I am loading the Stable 3.1 and following the procedure exactly, I have an acceptable upload with no errors.  BUT the unit after each re-do of this has LED fast blinking Red and I cannot connect via USB to MP or APM Planner, also cannot connect via 3DR radio.

I have also used the firmware from DIY firmware site and loaded as custom.  Exact same results

Any help would be appreciated.  Thank you  much, JEFF

    @Jeff,

    Do you have the speaker hooked up to the Pixhawk?

    If the Pixhawk startup sequence is like the PX4, which I have, you have to wait until the second set of tones before connecting via MavLink. The first set of tones is the boot loader followed by a moment of silence and then the second set of tones after which you should be able to connect via MavLink.

    I assume that you have the correct Com port and baud rate selected and the SD card inserted in its slot?

    Also I have found that using a powered USB hub can help with the USB communication issue. Both the PX4 and Pixhawk take a fair amount of USB current especially with the GPS/Compass module attached.
