Hi, newbie calling, I’m trying to put together my first autopilot with the Navio2 and a Raspberry Pi B+, using the latest Raspbian release (Stretch), http://files.emlid.com/images/emlid-raspbian-20190227.img.xz, of which the archive has in it emlid-raspbian-20190227.img, which I burned using the recommended tool. (I’ve also tried using Win32DiskImager). When the Pi boots onto this card, the green LED flashes seven times, which apparently means kernel.img not found.
The same SD card put into another Pi (model unknown, its in a screwed together box, it normally runs LibreElec for the TV) boots just fine, so there is nothing wrong with the Navio image, or the burn, or the card. The LibreElec SD card boots up fine on the B+ with the Navio2 on it.
I’ve tried removing the Navio2 card from the Pi B+, and booting the B+ on the Navio image, but that didn’t work either.
The only possibility not accounted for I can see is that the Navio image won’t run on the B+.
Is there something I am missing here, or is there some reason the B+ can’t boot on this image?
Just for final info, I’m using a genuinely branded Raspberry Pi power supply
