Do you have a serial console TTL to see any output? You likely want to follow the image creation section using the Fedora built u-boot from the README in upstream U-Boot: http://git.denx.de/?p=u-boot.git;a=blob_plain;f=board/amlogic/odroid-c2/README;hb=HEAD > I was able to find an older fedora 25 image using a modified 3.14 kernel > that boots so I'm attempting to go through the upgrade process for this > currently. I have no idea what process that uses but I doubt it's compatible, userspace should work fine but I'm sorry this isn't really supportable because we don't have the time and resources to support some random image. I've had reports that the C2 works OOTB with Fedora kernels. > On 07/08/2018 08:05 AM, Peter Robinson wrote: >> On Sat, Jul 7, 2018 at 10:49 PM, Dr. Zenzic <dr.zenzic@xxxxxxxxx> wrote: >>> Hello All, >>> >>> Has anyone had any luck getting Fedora 28 to work on the Odroid C2? >> I've had a number of reports it works just fine.
