Generate a device tree without a processor in the firmware design

Jump to solution

Hi,

I have a firmware design with GPIO's for configuration, intended to be programmed by an external CPU.

I've been trying to generate a device tree for this design from Vitis, but it seems like it requires a processor in the design itself.

Is there any way of doing this without needing this processor?

Many thanks.

No, the DTG (devicetree generator) needs a processor. You will need to add the node manually

https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/gpio/gpio-xilinx.txt

 

You could hack the DTG to allow this, but it wouldnt be worth the effort for just one node
