library selection when creating S32R274 project

guangyuanh — Mon, 20 Nov 2017 06:57:41 GMT

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.

Stan

Hi Stanislav:

Many thanks for your detailed description. It is clear to me for this question.
