NI CompactRIO 19.6 and Drivers Bug Fixes

Firmware Update when Bitfile Downloaded to Memory Can Cause Unrecoverable Error or Failed Software Installation

An unrecoverable error due to Safe Mode corruption can occur when updating firmware on certain RIO targets if a large bitfile is currently in flash memory. In some cases, the firmware update is successful and there is no unrecoverable error, but software installation on the target will fail. This issue only occurs in RIO targets with a Xilinx Zynq FPGA chip that have a large bitfile downloaded to flash memory.

Note: This is not the only cause of an unrecoverable error on RIO targets with Xilinx Zynq FPGA chips.

Workaround: If the RIO status light shows an unrecoverable error (continuous flashing), contact National Instruments Technical Support and reference this Known Issue to receive the recovery instructions.

If the firmware update is successful but the RIO is unable to install software, recover in one of the following ways:

• Revert to the older firmware version
• Enable SSHD and manually remove the lvbitx file that was downloaded to memory in the /boot partition

To prevent this issue in the future:

• Erase the bitfile from flash memory before updating firmware
• Update to NI CompactRIO 19.6 and Drivers

NI 9202 FPGA IO Nodes Acquiring Faster Than Maximum Data Rate

Adding an NI 9202 to a CompactRIO project without configuring the module properties or programmatically setting the data rate will cause the NI 9202 FPGA I/O Nodes to acquire data at a rate faster than the maximum data rate. This can lead to invalid data or the error 65539, but it is not the only cause of error 65539.

Workaround: For more information on the below workarounds, see the Additional Information section in  KnowledgeBase article "Error 65539 Using FPGA I/O Nodes with NI 9202."

• Right-click the module in the LabVIEW Project and select Properties. Configure the settings or click OK.
• Programmatically set the data rate.
• Update to NI CompactRIO 19.6 and Drivers

Export to CSV in the LabVIEW CLIP Generator Ignores sbRIO Bank Voltages

Using the Export to CSV option in the LabVIEW CLIP Generator exports the CLIP parameters for I/O pin bank voltages incorrectly. This results in an incorrect CSV file and only the default pin configuration being set when using the file for import.

Workaround:

• Manually change the bank voltages in the CSV file after exporting
• Change the incorrect bank voltage values in the LabVIEW CLIP Generator after importing the incorrect CSV file
• Update to NI CompactRIO 19.6 or later and then export the configuration
