Issue Details

I have a data acquisition system, based on an NI Linux Real-Time (RT) controller and different DAQ modules that are being accessed and controlled through the NI-DAQmx driver. Even though I am setting the corresponding NI-DAQmx tasks correctly, I keep getting error -201377, when trying to start the task.

Error -201377 occurred at an unidentified location

Possible reason(s):

Device is unusable while firmware update is in progress.

The error is shown in the following dialog box:

I have reviewed in NI MAX the current status of my RT controller, and I am not currently upgrading the firmware. What could be causing the issue?

Solution

Error -201377 could be caused by not having the latest available firmware version installed on your RT controller. To solve the issue, upgrade the firmware on your controller:

For compactRIO, myRIO, compactRIO Single-Board, NI ELVIS III, and compactDAQ controllers, you can follow the instructions listed in Upgrading or Downgrading Firmware on an NI Linux Real-Time Device.
For PXI(e) RT controllers, you can refer to Updating PXI Chassis, Controller Or Card Firmware.
