difference between the 'Xilinx Wiki Zynq Linux' and Petalinux flow

[ronnywebers]

I'm using Vivado 2015.4

If I understand it correctly, there are 2 ways to work with Linux on Zynq devices

Method 1: a 'manual' flow according to the Xilinx wiki

http://www.wiki.xilinx.com/Zynq+Linux

we currently use this method, so manually generated u-boot, kernel, dts -> dtb, ...  We also use Ubuntu as root file system

Method 2 : using petalinux tools

so far we didn't make use of the petalinux tools (but maybe that's a wrong idea), as we wanted to use a different RFS (Ubuntu). But the flow seems so much easier, so I have the following questions :

1) is the 'wiki flow' an older way of working, from before the Petalinux tools? Or what exactly is the difference between both flows?

2) Could we use the petalinux tools to generate everything except the RFS (or just don't use the Petalinux RFS, but replace it with our Ubuntu RFS?).

You can consider PetaLinux tools as a platform that eases building Linux based products. It helps customize, build and deploy Embedded Linux solutions on Xilinx processing systems.
