Debian with kernel 4.0 and fex script

[marpasternak]

Is it possible to use fex/bin script to boot Debian with kernel 4.0?

Regards,
Marcin

I think no.  Use DT (device tree).

Thanks for reply. The main problem is that I want to use two ethernet interfaces. Fex file has a easy to understand syntax, and I haven't any problems to adjust it, but I don't know how to modify DT. Could someone provide some informations what I have to do?

Isn't it in the Linux kernel doc tree?

You mean this?:
https://github.com/RobertCNelson/dtb-linux-dev/blob/master/src/arm/sun7i-a20-olinuxino-lime.dts
https://github.com/RobertCNelson/dtb-linux-dev/blob/master/src/arm/sun7i-a20.dtsi

These files are dedicated to Lime platform, and there are information only about Gigabit Ethernet interface. I have A20-SOM board with A20-SOM-EVB, and I want to use Gigabit Ethernet (which already is in A20-SOM-EVB), and normal 100Mbit Ethernet (I made my own module connected to GPIO-3 / PH pins).

In fex file I have:

I didn't tested it yet, so it's only an idea.

Edit:
My english isn't perfect and I misunderstood you. You mean I have to search information about modification DT in the Linux kernel doc tree. I will do it.
