Is it necessary to create NPF file for LIN Communication in S32?

[mbtmxk1]

now i am start to develop about lin communication,after read the LIN User Manual , i was told that the development sequence should do as below:

1.create npf and ldf file and generate .c/.h files(lin_cfg.c lin_cfg.h lin_hw_cfg.h),then copy them to your source project 

2. finish your Lin logic in application layer

3.compiling the source code to verify your function

is it correct?

but  i can not see any npf files in Lin examples project in S32 Design Studio for ARM,only ldf file can be found inside,Why? why the generated file contains lin_hw_cfg.h which is supposed generated by NPF file? and when i intended to create a npf file i can not found any proper mcu name in option list (KEA-144 i used now)....

Thanks

Hello, 

I'm not much familiar with the LIN interface - but you can start with S32DS LIN example. Click on File -> New -> Project from Example and choose S32K14x_EAR_SDK_v0.8.5 Example Project lin_master_s32k144

I assume that the node config file (npf) is part of processor expert:

thank you for your reply,Jiri.

I did create and analyse the  S32DS LIN examples(Master and Slave), only ldf file could be found in inside, so i just doubt the necessary of NPF for LIN configuration.do you have any idea about this?

Hi, 

the NPF file is not used for S32DS and SDK. Info from NPF is inside Processor Expert lin_cfg.
