I have a beagleboard rev c4 and have a zippy2 ethernet combo board.I install ubuntu 14.04 on the beagleboard (GNU/Linux 3.15.3-armv7-x4 armv7l) i have a problem with zippy2 board.How to enable zippy2 board?I add kernel parametar buddy=zippy2 but this not solve the problem.(Kernel command line: console=tty0 console=ttyO2,115200n8 buddy=zippy2 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait fixrtc).Another problem is that in my serial port i get omap_i2c 48060000.i2c: timeout waiting on XUDF bit and omap_i2c 48060000.i2c: controller timed out why?

Wait! You mean someone is still using the "zippy2"! 
I think i have
one laying around somewhere, we need to write a custom *.dts for it.
The old "buddy=xyz" trick isn't going to work in a device tree world.
Another problem is that in my serial port i
get omap_i2c 48060000.i2c: timeout waiting on XUDF bit and omap_i2c
48060000.i2c: controller timed out why?
Yeah, this started in mid v3.13-rcX haven't tracked it down yet.
Regards,
can you write a custom *.dts because this is very important i need to work with zippy2 board in combination with beagleboard!
thanks for all your help!!!
