Hello guys,
I want to utilize old APM1(2560) board for AntennaTracker and want to upload there FW of version 0.8.0 via MissionPlanner. When I hit “Load previous firmware” after detecting board version and start of downloading firmware for it I get error:
"The hex file did no contain an end flag. aborting"
Seems like there is no built hex file in repository there to download. Will it be possible in future yet?
I can’t upload AT 1.0.0 because of APM1 hardware limitations. Therefore I’d like to have there 0.8.0 version.
I also tried to compile it from sources by my self (with PX4 Toolchain) but have no luck yet 
I’m trying to get AC3.3.3 for Trad Heli and Mission Planner won’t connect to get that either.
I just tried an apm with a 2560 on it and it loaded AT 1.0 fine. this was without using any previous firmware options
what board are you using?
It was a PX4. But the problem was Windows. I don’t actually use Windows, and I borrowed a laptop from a friend with Win7 in it, and installed MP in it, so I could put AC3.3.3 Heli on the board. But it kept failing with an error. And some error about .NET when it started MP up. I really hate Windows. So I borrowed yet another laptop with Win10 in it. And despite Win10 being a bigger kludge than Win7, it actually worked and I got AC3.3.3 on my board.
