If the driver is loaded successfully, but the ntservice daemon or NTService has failed to start, please check if the driver version is compatible with the SmartNIC FPGA image / AFU. The compatible FPGA versions are listed in the release note of the driver, e.g. Release Note for Napatech Link™ Software Driver Version 3.22.1 (filename: nt_driver_3gd-linux-3.22.1.html).
Please confirm with Napatech Technical Support that the SmartNIC has the correct part number so that the associated FPGA version can be checked from the part number of the SmartNIC.
In this example 801-0074-08-00 is the part number (PN) of the SmartNIC.
Some part number labels include a revision in the part number, for instance 810-0029-01-02-03. The revision is not displayed by the productinfo tool.
