Issue Potential Cause Fix
XRT package fails to install in
CentOS7.4 or CentOS7.5
Kernel development headers are
missing. The XRT package is missing a
dependency on
kernel-devel
and
kernel-headers
.
Manually install
kernel-devel
and
kernel-header
with yum install:
$ sudo yum install kernel-
headers-`uname -r`
$ sudo yum install kernel-
devel-`uname -r`
Note
:
Do not run
sudo yum upgrade
.
This will update the kernel-headers to an
incompatible version.
Flashing the card does not complete
after 20 minutes .
The flash operation has failed. Perform cold-reboot and then re-flash
the card.
Run time fails with following message:
Error: Failed to find Xilinx
platform
Failed to source the
setup.sh
script. Source
/opt/xilinx/xrt/setup.sh
When installing XRT, you see the
following message:

downloading as file '/root/
xrt_201802.2.1.79_16.04.deb'

'_apt'. - pkgAcquire::Run
(13: Permission denied)
This is caused by running
sudo apt

The XRT will install correctly, despite
the error. You can find more
