Greetings:

    would anyone help me about the differences between the EWL/EWL Nano/NewLib/NewLib Nano as below? 

    I used to select the EWL library in MPC5775K project by default. I'd like to know if it is the most suitable selection for radar signal processing?

Hi,

There are basically two main Ansi C/C++ libs familes supported by S32DS: Newlib and EWL

Newlib

Newlib-nano

  • Newlib variant that is targeting memory constrained devices (e.g. no floating point support for std. I/O)

EWL (Embedded Warrior Library)

  • proprietary libraries created by NXP (source code available and distributed with S32DS/CodeWarrior)
  • maintained by NXP
  • easy migration from CodeWarrior projects
  • good scalability via config macros 

EWL-nano

  • EWL variant that is targeting memory constrained devices (currently smaller footprint then Newlib-nano)

S32R274 is a device with enough memory ~2MB internal Flash/ >1 MB of onchip SRAM. So you can choose between EWL and Newlib.

Hope it helps.
