ZCU111 build error - Could not resolve host: github.com (embeddedsw)

Support
1

Hi,

I am building ZCU111 Pynq image.
During the build process, I am getting following error
fatal: unable to access ‘GitHub - Xilinx/embeddedsw: Xilinx Embedded Software (embeddedsw) Development’: Could not resolve host: github.com
Tried more than 3 times to triple check that it is not a network error.
I can easily access github.com and clone “embeddedsw” repo manually. No issues.

I am using Ubuntu 18.04.3. Using the Master branch for both Pynq and ZCU111-PYNQ

Hmm…
Could you try:
“git clone GitHub - Xilinx/PYNQ: Python Productivity for ZYNQ -b v2.5.1” ← This is official release of PYNQ and it worked for me several times.

Also, you could try first make image for Pynq-Z2 just for test.
If it builds that means error is in ZCU111

I tried v2.5.1 with Ubuntu18. It is not compiling under under Ubuntu18.
However, v2.5.4 (and Master Branch) works fine with Ubuntu18 and no issues with Pynq Z2 compilation.

I tried latest master branch with Ubuntu16 and Vivado, Petalinux 2019.1
Build process worked like a charm.
However, found some issues after linux boot on A53 processor.
I will raise it in another post.
