cora z7-07s Help programming Cora Z7-07S PL through Petalinux

[JPP75]

Hi Everyone,

 

I'm new to Zynq FPGA and I have some difficulties to understand how to program the PL through Petalinux.

I have a Cora Z7-07S board and by fallowing Digilent's instruction (https://reference.digilentinc.com/reference/software/petalinux/start), I'm able to boot Petalinux on a SDcard and SSH to it.

I can also load the basic PL demo (https://reference.digilentinc.com/reference/programmable-logic/cora-z7/cora-z7-07s-basic-io) through the JTAG with Vivado.

But I'm struggling trying to program the PL with the same demo program trough Petalinux.

If I understand correctly this guide: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841645/Solution+Zynq+PL+Programming+With+FPGA+Manager, I have to change the device-tree to add the top.bit.bin.

Does anyone know which files of Digilent's BSP should be changed and how? Can anyone provide a step by step guide?

 

Thank you

Hello,

The Xilinx guide you mentioned is relevant for versions starting with 2018.1.

Since our Petalinux project on github is using 2017.4, the procedure is a single command.

$ cat bitstream.bit > /dev/xdevcfg

Here is the reference for versions 2017.4 and earlier:
