Petalinux ExpansionError on petalinux build

[Septyawan Aulia]

Dear All,

I am a newbie both in FPGA and Embedded Linux but I bought a Cora Z7-07s and try to use Petalinux. I follow https://github.com/Digilent/Petalinux-Cora-Z7-07S quick start guide. I'm using Ubuntu 16.04 LTS in VM with Win10 as host. there is no problem until I begin to build the project which I found an error

Dear vicentiu.

thank you for helping me. now I already installed the Petalinux 2017.4 in the same system and try to build the project again.

now I found another problem, when Generating bbappends it take almost forever the failed. I tried it many times.

Is there any problem or skipped step that I am not done yet?

Thank you

I was able to successfully run 

petalinux-create -t project -s Petalinux-Cora-Z7-07S-2017.4-1.bsp

Here are some common errors people make. Make sure you meet the following conditions:

1. You can only have one version of Petalinux installed. If you have more, you will get build errors on both.
2. Petalinux has to be installed in /opt/pkg/petalinux. (./petalinux-v2017.4-final-installer.run /opt/pkg/petalinux)
