Issue Details

After compiling my FPGA code, I try downloading it to an NI 9144 EtherCAT chassis and get the following message: Error -2147138268 occurred at  How do I resolve this error and successfully download my FPGA code to my EtherCAT target?


This error is generally caused by failing to deploy the EtherCAT master.
To do this right-click the EtherCAT master and select Deploy.

This error can also be associated with a firmware mismatch between the NI 9144 and the NI-RIO and NI-Industrial Communications for EtherCAT drivers. In order to successfully download your FPGA code, update the firmware on your NI 9144. This process is outlined on pages 15-16 of the NI 9144 User Manual.
