Enable Hybrid Mode

To enable or disable hybrid mode, and so make the card programmable, download one of the
following collections of hybrid upgrade files:

• XN-201355-LS Alveo X3 Hybrid Upgrade [RPM package], recommended for Red Hat, SUSE or

CentOS

• XN-201356-LS Alveo X3 Hybrid Upgrade [Debian package], recommended for Ubuntu or

Debian.

Install the Update Files

Install the package of .update files that you downloaded:

1. Log in to the x86 host for the X3522.

2. Copy the package from the remote host to the

/tmp

directory on the x86 host:

• On the remote server:

# scp <path_to_package> root@<x86_host_ip_address>:/tmp

• or on the x86 host:

# scp <username>@<remote_host>:<path_to_package> /tmp

3. Install the .update files from the package:

• For an RPM package:

rpm -ivh <package_name>.rpm

• For a DEB package:

apt install <package_name>.deb

The .update files are installed in the

/lib/firmware/xilinx/x3

directory.

Program the FPGA

The .update file is applied using standard Linux utilities:

• The devlink command is preferred.

Devlink reports progress in more recent versions, and does not block while it is running.

• The ethtool command can instead be used.
