APM 2.6 and 3.2.x firmware

Posted by David Pulvermacher on July 18, 2015 at 2:58am

I'm running an APM 2.6 clone, which was fine on 3.1.5 firmware. I misguidedly upgraded to 3.2.1 last week and did an autotune with horrible results.

I want to revert back to 3.1.5 firmware, but in MP latest, if I try to download ealier or custom firmwares I keep getting an error...Any other way of doing it?

If I import the parameters from the previous autotune, which worked fine, I hope the craft will revert back to it's previous state..Is that so?

    Thanks Randy. Achieved the install by downloading 3.1.5 manually and then did a 'custom install'.
    By the way can you tell me which FW (date?) has the Drift mode included?

    David,

    I used the MP's "Pick previous firmware" link on the Initial Setup >> Install Firmware screen to install AC3.1.5 succesfully to my original 3DR APM2 after first uploading AC3.2.1 so the upload of AC3.1.5 should work I think.  Maybe double check the COM port is correct, plug and unplug the APM2 a few times, reboot the PC, etc.. you know, the regular antics.
