Can not load the devicetree

[tadifiore]

Hi,

I download Pynq-image-2.4, and it is running in my Pynq-Z1.

In the boot patition i found two files: BOOT.bin and image.bu, but there is not a file named devicetree, so i can not change it to instance framebuffers settings

I follow the read-me file, and compile the modules kernel. I reach to make the pynqz1fb.ko and instance it in my Pynq, but nothing happens, i suppose because devicetree.dtb is not loading.

Is it possible that i need to compile the kernel to obtain a new image to load the device tree?
Are there any documentation recommended to do that?
