RTD is not officially supported on Linux because the Case Sensitivity on Linux OS.
To make the RTD working on Linux, need some changes in folder: /NXP/S32DS.3.X/eclipse/mcu_data/components
Please read the 'ReadmeToModifyTheRTD.txt', I only did the neccesarry changes for my project, for other codes may need more changes.
Just my opinion: Linux OS has much faster performances when S32DS doing the code's compiling and debugging. NXP should officially support it, including the RTD ~
