When I am deploying CD to Linux RT, The error occurs like this

[LIANSHI]

Background：At the beginning, I generated a CD project through the official NI custom device template tool, and found that if it is to be deployed to NI linux RT, some additional settings and modifications are required.Then I spent a lot of time on it , and Then I succeed. But I found if the CD is the empty one ,then I can succeed to deploy it. but if I add some channels, and some computation in it (main page.vi/ installation.vi/ RT driver.vi). it will have this error:

here is the linux RT side:

the whole error expanded are :

Deployment Error

Error -307682 occurred at Project Window.lvlib:Project Window.vi >> Project Window.lvlib:Command Loop.vi >> Project Window.lvlib:Connect to System.vi

Possible reason(s):

NI VeriStand: Could not complete one or more requests because a target is offline.

So I don't have the direction to fix, I only add some simple stuff on my CD project.So can you please help me to analyze this issue? it is really urgent for me. Thanks.

Can you try to create your custom device using niveristand-custom-device-wizard instead of the template shipped with the VeriStand? You might have modified the settings incorrectly at some point. This consolidated template has the Linux RT configured correctly.
