PetaLinux build can fail with the following timeout error in XSCT:
The following work-arounds can be used to overcome this issue:
1) Increase the timeout in XSCT.
2) Clean up using the following commands:
rm -rf ~/.Xil
rm -rf ~/.Xilinx
Note: This error could be due to a resource constraint on the PC.
The minimum configuration required for PetaLinux tool installation is 8 cores and 8GB RAM (This is not corrected in 2016.4-2017.2 (UG1144) documentation).
Ideally one project should be built at a time.
If you want to run projects in parallel, set parallel threads and configure execution in petalinux-config->Yocto Settings to lower values which match your system configuration.
