PXIe-7903 or PXIe-6954 will fail to compile a bitfile if LabVIEW is not run in administrator mode

When run from LabVIEW without administrator privileges, PXIe-7903 or PXIe-6954 FPGA applications will fail to compile bitfiles in the codegen step due to permissions error copying files to the lvaddons directory. 

Workaround:

Run LabVIEW in Administrator mode when compiling bitfiles.

PXIe-7903 100GbE example does not respond to ARP requests

The PXIe 100GbE example doesn't respond to ARP requests sent to it by connected systems. This can manifest as data sent to a Sasquatch not being received, because the connected system doesn't know where to send the data.

Workaround:

Manually configure the ARP table of the system connected to the Sasquatch. On Windows this can be done with the command `arp -s <sasquatch IP> <sasquatch MAC> <IP of sending NIC>`. e.g. `arp -s 169.254.122.138 01-02-03-04-05-06 169.254.122.137`

PXIe-7890 Errors when Being Added as a Target in LabVIEW 2021

Adding a PXIe-7890 may report an error when being added as a target in LabVIEW 2021. The error message will be "An internal software error has occurred in LabVIEW FPGA". 

Workaround:

There are 2 possible workarounds -

  1. Use LabVIEW 2023 Q1 or later instead of LabVIEW 2021
  2. On a fresh system, first install LabVIEW 2023 Q1 or later on the system, followed by LabVIEW 2021 and the FlexRIO driver. This will enable using LabVIEW 2021 and the FlexRIO driver to add a PXIe-7890 as a target
