Creating Boot Image for Zynq

Hello guys,

 

I'm trying to rebuild boot files for my zynq board from scratch. But so far it proves unsuccessful...

I work with the 2014.2 release, and Xilinx tools 2014.2 (Vivado, SDK, Petalinux).

I follow this guide: here.

 

From the hdl master branch, I was able to build the hardware and the bitstream files.

From the Vivado project, I generated the associated devicetree with SDK (.dts). I compiled the file into .dtb (with dtc linux command).

 

Then in order to generate the FSBL project, I need the bitstream file (I have it), the zynq_fsbl.elf file (I have it from Vivado as well) and the u-boot file (need to generate).

 

To generate the u-boot file, I use this Wiki Xilinx guide.

I am able to generate the uImage file with the linux git branch from analogdevicesinc github (git clone command). Thing went fine and I have my uImage file.

I also need the devicetree.dtb file that I generated previously.

But now I need to generate the uramdisk image.From the 2013.1 release, the Zynq uses uses initramfs. However, I don't know how to proceed.

 

Can you give me some hints?

Thanks
