Hi,

I wanted to recompile the Linux Kernel for NanoPi Duo following this tutorial: http://nanopi.org/nanopi_development.html#5 .
After replacing the zImage on the sdcard the Nano Pi Duo hangs on boot. I guess there's some configuration required to create the correct zImage.
Unfortunately I couldn't find any documentation regarding this. Can you help me with that?

At the end my goal is to set a higher I2C Frequency which appearently can only be done by recompiling the kernel. Or do you know a better way to do this?
