Petalinux 2016.4 on Ubuntu 16.04 LTS - xilproxy segfaults after "ERROR: Failed to source bitbake"

[wzab]

When I try to import the HW description from my Vivado project, I get segfault:

wzab@isw:~/petalinux/multi_eth1$ petalinux-config --get-hw-description=/home/wzab/test16.4/Xilinx-ZCU102-2016.2/Xilinx-ZCU102-2016.2.sdk/design_1_wrapper_hw_platform_0

An attempt to analize the core file with gdb does not provide any useful information:

Is there any solution known for that problem? Maybe the main problem is "ERROR: Failed to source bitbake"?

How to resolve that?

TIA & Regards,

OK. It's my fault. I have attempted to install Petalinux for all users as root, and I have missed the following error message:

INFO: Checking installation environment requirements...
INFO: Checking free disk space

Please refer to the PetaLinux Tools Installation Guide.

Check the troubleshooting guide at the end of that manual, and if you are
unable to resolve the issue please contact customer support with file:

 I have reinstalled PetaLinux as a normal user, and it has solved the problem!

Hmmm, in fact xilproxy still fails:

[INFO] generating petalinux-user-image.bb
Generate petalinux-user-image  bb file
webtalk failed:Invalid tool in the statistics file:petalinux-yocto!
webtalk failed:Failed to get PetaLinux usage statistics!
sh: line 1: 15808 Segmentation fault      (core dumped) /home/xl/petalinux-v2016.4/tools/webtalk/bin/unwrapped/lnx64.o/xilproxy > /home/wzab/petalinux/multi_eth1/.Xil/Webtalk-15804-isw/webtalk/xilproxy.log 2>&1

 petalinux-yocto is available in tools/common/petalinux/utils , but it is not added to the PATH by sourcing of "settings.sh".

I have added it afterwards with:

 export PATH=/home/xl/petalinux-v2016.4/tools/common/petalinux/utils:$PATH

The above eliminates complaints about "petalinux-yocto", but xilproxy still segfaults:

[INFO] generating petalinux-user-image.bb
sh: line 1: 27703 Segmentation fault      (core dumped) /home/xl/petalinux-v2016.4/tools/webtalk/bin/unwrapped/lnx64.o/xilproxy > /home/wzab/petalinux/multi_eth1/.Xil/Webtalk-27699-isw/webtalk/xilproxy.log 2>&1
[INFO] successfully configured rootfs

However, I can configure the system with different modes of "petalinux-config" and build the image with "petalinux-build", so I do not consider it to be an important problem.

Could you explan what other modes you used? Thank you

The segfault is being caused by webtalk. You can turn it off in your project by using the command:

petalinux-util --webtalk off
