Use the imgctrl tool to query, program and switch to a new FPGA image.

Check the correct FPGA image number of the SmartNIC. See FPGA image types and numbers in DN-1128.

The imgctrl tool is a Napatech standalone tool which manages the FPGA image configuration of Napatech SmartNICs. This procedure describes imgctrl command examples to query, program and switch to a new FPGA image.

  1. Check the FPGA state of the SmartNIC. 
    /opt/napatech3/bin/imgctrl -q
    An output example:
    ...
Scanning for Napatech adapters..
Adapter 0:
     PCI SLOT        : 0000:42:00.0
     PCI DEVICE ID   : 01D5
     PCI LANES       : x16
     ADAPTER TYPE    : NT50B01-01-NEBS-2x25-E3-FF-ANL 2x25Gb SFP28 platform
RUNNING FPGA:
     FPGA IDENT      : 200-9541-35-20-0000
     DESCRIPTION     : 2x25/10Gb, capture
FPGA BANK0:
     PRODUCT CODE    : 9541
     VERSION         : 35.20
     DOWNLOADED BY   : ntope
FPGA BANK1:
     PRODUCT CODE    : 9541
     VERSION         : 35.20
     DOWNLOADED BY   : ntope
SUPPORTCHIP INFO:
     NT50B01         : v3.5s
FPGA IMAGE STATE:
     IMAGE STATE     : NEUTRAL (code 0)
     PRIMARY BANK    : 0
     RUNNING BANK    : 0

    There are two flash banks in the SmartNIC as shown in the output example. The currently loaded FPGA image is displayed as PRIMARY BANK which is bank 0 in this example.

  2. Enter the following command to list the available FPGA images. 
    ls -R /opt/napatech3/images/
  3. Program the FPGA with the appropriate image using the imgctrl command. 
    imgctrl -a 0 -p --ntimg <path_to_image_file> --ini <id_string>
    where:
    • path_to_image_file specifies the path to the .ntimg FPGA image file to be uploaded to the flash
    • id_string specifies a user-chosen identifier

    This is an example of the command to program the FPGA image.

    /opt/napatech3/bin/imgctrl -a0 -p \
--ntimg 200-9530-42-05-00-210601-2117.ntimg --ini cap
    An output example:
    ...
Scanning for Napatech adapters..

  Erasing................... 100% done
  Writing................... 100% done
  Verifying................. 100% done
Done writing FPGA bank 1
...
Upgrade process complete
    The FPGA upgrade must not be interrupted.
  4. Switch to the new FPGA image using the imgctrl command. 
    /opt/napatech3/bin/imgctrl -a0 -s
    Run the following command to complete switching the image.
    /opt/napatech3/bin/imgctrl -a0 -s --confirm
    An output example:
    Scanning for Napatech adapters..
Applying current running image as safeboot image..
  OK. Adapter PrimaryImage has been updated to reflect current running image.
  5. Switching to the new FPGA image may fail with an error as follows on some servers. 
    ...
Error: Adapter did not wake up after image switch. Please reboot machine to re-enable adapter.
       You may need to apply --pcirst next time you switch image.
  FAIL. Switching failed. Use --query to examine adapter
    You must reboot the server to be able to detect the SmartNIC again.
    reboot
    After the server reboot, check the image state of the SmartNIC.
    /opt/napatech3/bin/imgctrl -q
    An output example:
    ...
FPGA IMAGE STATE:
     IMAGE STATE     : FAILED (code 3)
...
    The image is in FAILED state. Run the following command to reset the image to the NEUTRAL state.
    /opt/napatech3/bin/imgctrl -a0 -s --discard
    An output example:
    Scanning for Napatech adapters..
Resetting bank switch statemachine back to neutral..
  OK. Adapter bank switch statemachine is reset back to neutral
    Check the image state again.
    /opt/napatech3/bin/imgctrl -q
    Confirm that the image is in NEUTRAL state and switch the image with the --pcirst parameter.
     /opt/napatech3/bin/imgctrl -a0 -s --pcirst
    An output example:
    Scanning for Napatech adapters..
Switching image on adapter 0:
  OK. Reboot required to switch image. Do not forget to --confirm/--discard the adapter once rebooted!
    Reboot the server.
    reboot
    Run the following command to complete switching the image.
    /opt/napatech3/bin/imgctrl -a0 -s --confirm
    An output example:
    Scanning for Napatech adapters..
Applying current running image as safeboot image..
  OK. Adapter PrimaryImage has been updated to reflect current running image.
  6. Confirm the FPGA image state. 
    /opt/napatech3/bin/imgctrl -q
    An output example:
    ...
Adapter 0:
     PCI SLOT        : 0000:42:00.0
     PCI DEVICE ID   : 01D5
