No /dev/epiphany device

[Pavel]

I have a Parallella board.
I had problems with ubuntu-14.04-140611.img image so I switched to ubuntu-14.01-lxde-14.03.06.img.
I also use Linux kernel without HDMI support (“headless”).
I have built Epiphany SDK but when I try to use E-UTILS (e-reset, for example) I get an error like "/dev/epiphany not found" .
Actually I see no "/dev/epiphany" device in the filesystem.
What can be the issue?

Ah, so my guess is that you've got a bleeding edge SDK which expects a kernel with Epiphany driver/module. However, the current kernel build doesn't have this AFAIK. Safest option may be to checkout an older commit of the SDK.

Someone else who knows more about this may also be able to comment further

Regards,

Andrew

Is there a kernel source tree available which supports the /dev/epiphany device?

Currently everything is done through mmap and /dev/mem, but we are currently working on a new driver here (some exciting stuff....)
