How to fix XRT package fails to install on CentOS7.4, CentOS7.5, or CentOS7.6 for Xilinx Storage?
- L

  If the XRT package fails to install on CentOS7.4, CentOS7.5, or CentOS7.6, it may be because the kernel development headers are missing. 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.

Why does the Xilinx Storage card fail to train to the full expected PCI Express link width or link speed?
- J
  jamiepenaSep 12, 2025
  If the Alveo card has not trained to the full expected PCI Express link width or link speed, ensure that it is plugged into a Gen 3x16 capable slot and that the power cable is connected. Then, perform a cold reboot to see if the card trains to the correct settings.

  If the Xilinx Storage card is not present when running `xbutil` or `lspci`, it might not have been ready when the server enumerated PCI Express. Try a warm reboot of the server and disable Fast Boot.

What to do if Xilinx Storage card does not show up when running lspci and the red LED on the card is illuminated?
- P
  Phillip WoodardSep 10, 2025
  When a Xilinx Storage card is first installed in a server, the BIOS may not recognize the card correctly, and the red LED on the card may illuminate, indicating an error. Try cold booting the server four times until the blue LED on the card is illuminated, indicating the card is successfully running. If the red LED is still illuminated, disconnect the power to the server for 5 minutes and repeat the step above.

How to fix 'Card not found' issue on Xilinx Storage?
- D
  Debra WilliamsSep 9, 2025
  If the Xilinx Storage card is not found, there might be several reasons: * The card may not be correctly installed. Reinstall the card following the installation instructions and check if the card shows up by typing the Linux command: `lspci -vd 10ee:.` * The card may not be compatible with the server. Ensure you are using a qualified server. Refer to the Alveo U200 and U250 Data Center Accelerator Cards Data Sheet (DS962) for system compatibilities. * The maintenance USB cable might be attached. Remove the maintenance USB cable before booting the system. * The kernel version may be incompatible. Run `uname -r` to check the kernel version. Ensure that the kernel version matches the version listed for your OS in Chapter 4: Installing the Deployment Software.

  If the XRT package fails to install in CentOS7.4 or CentOS7.5 for your Xilinx PCI Card, it is likely that the kernel development headers are missing. Manually install kernel-devel and kernel-header with yum install: `$ sudo yum install kernel- headers-`uname -r`` and `$ sudo yum install kernel- devel-`uname -r``. Note: Do not run `sudo yum upgrade`. This will update the kernel-headers to an incompatible version.
