Hello ep1015,

I have the same missing /dev/fpga0 device problem although the context is slightly different. The device is present if I boot from yocto.

I wanted to use ubuntu for package management reasons and have gone for the latest release of ubuntu desktop (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=836&partno=4) with the 4.5 kernel.

if I have understood your directions correctly, I took the kernel from the Yocto card, ran mkimage command in the SoC EDS shell and under Windows, dropped the uImage file alonside the zImage file in the FAT32 partition visible under Windows.

However I have had no joy after a reboot in seeing /dev/fpga0 device.

If you have any further ideas or can see fault with what I have done, I'd be most grateful.
