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 your more changes. The good thing is I've already made the sh files, simply 2 steps can make your work done.
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 ~ , NXP colleagues, take care the letters case sensitivity when you're coding, please.
