Issue Details

What bitness is the application running on my NI Linux RT Target? I am wondering if my RT EXE can fully use the memory (> 4 GB) on my 64 bit Linux RT system.


The LabVIEW Real-Time module (32 bit) installed on your development machine cross-compiles applications for both ARM (32 bit Linux) and Intel (64-bit Linux) architectures and the application bitness matches the bitness of the NI Linux RT target distribution.
  • cRIO-906x, myRIO, sbRIO-9637,07, and the SOM runs a 32 bit application (ARM targets)
  • cRIO-903x, cDAQ-903x runs a 64-bit application (Intel targets)
