I’m trying to flash copter quad 3.5.7 to a black cube. I get to the point where I unplug, click ok, then the instant I plug in the USB cable I get the error in the attached screenshot.
I’m using the latest beta of MP 1.3.59.3.
I can flash 3.6 without any problems.
Where can I download the binary for 3.5.7 so I can try loading it locally?
Hmm, as I mentioned I thought I was on the latest beta. Just to be sure I clicked “check for beta updates” again and I still can’t get this to work. Here’s a line from the console window - am I on the right version?
INFO MissionPlanner.Utilities.Update - New file Check: local 1.3.6878.40374 vs Remote 1.3.6878.40374
Here it is. I started a new log file. I connected to the cube on com5 to verify MP could do that, then disconnected MP and tried to flash quad 3.5.7. As soon as I plug in the cube after the power cycle I get the invalid URI error.
I can flash current firmware just fine, it’s only when I try 3.5.7 that I get this error.
I did some more testing on this problem. To eliminate the possibility of a problem with my laptop or Mission Planner installation, I took a different computer, empty disk partition, installed Win 10 Pro from scratch, installed Mission Planner, updated to Beta (1.3.6885.41507), and tried again to flash ArduCopter 3.5.7 Quad to the Cube. I’m still getting the “Invalid URI error” and flashing fails. Installing ArduCopter 3.6.0 works fine.
I’ve got multiple Pixhawk 2.1 most of them with older firmware, one with 3.6.0 and I get the exact same message as shown in the first post for all of them when I want to go to 3.5.7.
I can not use 3.6.0 since I’ve got some lag of around 1 s in the servo signals over mavlink which makes it hard to control my gimbals precise.
I’ve tried the actual stable Version of Mission Planer and the latest Beta 1.3.59.3 build 1.3.6885.41507 as well.
