I’m happy to announce, that volumio 2 is now running on cubox-i (iMX6 devices).
Due to dependencies, the stock kernel 3.14 could not be used.
Volumio is using kernel version 4.7.2 instead, this means currently headless (no graphical support).
I have a first version running smoothly with a usb dac.
There is an issue with spdif output which needs to be solved (driver loaded, but no sound).
No ETA yet, as this needs to be fixed and more testing needs to be done.
A big THANKYOU to forum member Gribouille, who lent me a cubox-i2ex to configure the kernel, u-boot and develop the build scripts.
