I have (had) Yocto working on my Intel Aero drone perfectly, including connecting with QGroundControl. I also upgraded the Bios and Flash to version. When I ran aero-get-version.py it gave me the BIOS_VERSION = Aero-01.00.16, OS_VERSION = v1.6.2, AIRMAP_VERSION = 1.8, FPGA_VERSION = 0xc2 and Aero FC Firmware Version = 3.5.3. No problems with Yocto at all.
I created the usual Ubuntu 16.04.5 LTS Desktop USB (ubuntu-16.04.5-desktop-amd64.iso). When I try installing it, it momentarily flashed an error that said "Error, cannot find /boot", but then on pressing Esc went to the GRUB 2.0 menu that showed "Try Ubuntu without installing", "Install Ubuntu", "OEM Install.." and "Check disk for defects".
When I entered "Install Ubuntu", it reached the initial Ubuntu splash screen with the Ubuntu logo and the cycling orange and white dots. However, it did not get beyond this even after 1 hr. This this once again and same thing. Then I tried "Try Ubuntu without installing" -- same thing, and then "OEM Install.." -- same thing. Just stays stuck on the Ubuntu logo with cycling dots.
Just to make sure there was no problem with the Flash disk, I tried "Check disk for defects" and it went through all the checks and finally returned "Check finished no errors found. Press any key to reboot your system".
Can you please tell me how to install Ubuntu? Otherwise I have a $1000+ brick...
