I cannot seem to find the answer to my question on the existing posts therefore I open a new one.
I am trying to load a custom firmware (APM 2.6 , Arducopter) in the latest mission planner which I downloaded today. When I click on “Pick custom firmware” I can see older version but just the one I need is not there . I need firmware V3.1.3 which has a hash of aefeb38b. Have a look at the picture.
According to release notes the firmware was released on 2014-04-07 but I cannot find it under http://firmware.diydrones.com/Copter/
Another question is how is hash calculated, what algorithm is used to calculate it, does not look like SHA or MD5 ?
