I have device named "atol hub-19" with A20, runs on old 3.4 kernel (fex based system configuration) ... there is a way to do convert .fex to dt ? I used Armbian_5.59_Lime2_Ubuntu_xenial_default_3.4.113_desktop.img and change script.bin... and the device works fine

did you already search in the armbian documentation for your problem ?

 

Yes, but I didn't found any usable information ( I'm a little newbie ) , if You point Me to "how to" manual I'll be very glad

I am not sure such how-to or tool exists. Fex is nonstandard Allwinner way of defining hw while DT is version dependent.

my bad, I mixed fex/bin with DTB.

However, here you get some idea about what hast to be looked at here https://linux-sunxi.org/Device_Tree
