Issue Details

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


The LabVIEW Real-Time module 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. Refer to Real-Time Controllers and Real-Time Operating System Compatibility to check which architecture your Real-Time target is using.
