Error in Device Tree FIle

[engr.majid]

 I installed PetaLinux2016.1 for Creating Linux Image for Zybo Board. I have BSPs for Zybo Board with version 2015.4.

I created a Hardware system in vivado involving only Zynq PS and Two GPIOs one for Buttons and one for LEDs. I exported hdf file to Petalinux project. I then try to build petalinux project but it ends with the error as under:

ERROR: Failed to build linux

Is this due to version mismatch of BSPs and Petalinux software or some thing else?

Hi,

Are you using Vivado 2015.4 generated hdf with Petalinux 2016.1? If yes, then you will need to upgrade/migrate your 2015.4 hardware design/project to Vivado 2016.1 and generate hdf, export to 2016.1 SDK and generate BSPs and proceed to Petalinux(use 2016.1 generated hdf). Using different versions combination may lead to complicated errors.

I was actually not configuring hdf file in the petalinux project. Adding Hardware configuration solved these issue. Thanks...
