Hi Expert

I have some questions about S32 studio

1. what are the different between "EWL,EWL Nano,NEWlib,NEWlib Nano "

2. How to modified the library(reelect the library) after the project has been created finish.

3. I used library of EWL . If I used lib API of "vprintf" in a freertos task ,the system  will be crash. whatever the heap size  that I give to this task (I most give to 5K). If I haven't used in freertos task is ok

So could you tell me how to solve it.

Hi, 

I'm afraid that there is no summary about EWL library variants. Each variant depends on build parameters. You can check them in [YOUR_S32DS_INSTALL_PATH]\S32DS\arm32_ewl2\lib\

You can change C library in existing project in project properties and rebuild your project:
