UG1301 (v1.5) June 3, 2020
Getting Started with Alveo Accelerator Cards
Potential Cause
Driver has not loaded successfully or
the card is not flashed successfully.
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
xbmgmt commands do not work. There
are no errors indicating this in output.
Chapter 7: Troubleshooting
Fix
Perform a cold reboot.
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
