General
UG1301 (v1.3) February 12, 2019
Getting Started with Alveo Accelerator Cards
Potential Cause
Kernel development headers are
missing. The XRT package is missing a
dependency on kernel-devel and
kernel-headers.
The flash operation has failed.
Failed to source the setup.sh script.
This is caused by running sudo apt
install as root.
Description
On CentOS 7.5, driver may not be
loaded properly after boot up (or
reboot).
Chapter 7: Troubleshooting
Fix
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.
Perform cold-reboot and then re-flash
the card.
Source /opt/xilinx/xrt/setup.sh
The XRT will install correctly, despite
the error. You can find more
information about this error on
AskUbuntu.
Comments/Recommendations
After boot up (or reboot), run these
two commands to load the device
driver:
$ sudo rmmod xclmgmt
$ sudo modprobe xclmgmt
