Without a log it is difficult.

Read this:

You will most likely have to post a link to the log stored elsewhere (Dropbox, etc.)

it displays no log to download.
what should i do now?
Right because you haven’t made a flight apparently. This error indicates your GPS is at fault which also may generate the bad velocity error.

pre arm check is okay.but apm is not arming whenever i am trying to arm it by shifting the throttle of the transmitter to right for 5 second. apm is still blue led solid and red led blinking. whats the problem?
