stdio.h in DS for S32K118

Dear Officer,

I am working on S32K118 with Design Studio. It supports the stdio.h as standard. Is there any linkage between this stdio with DS debug? e.g. steerr, stdin and stuout can be "displayed" via any DS window? (The Console, Debugger Console and Debug windows seems not related with it).

 

Thanks and best regards

He Wei

Hello He,

I'm not aware of such document.

EWL comes from Freescale/NXP, NewLib is a standard distributed under freeware license:

https://sourceware.org/newlib/

Some introduction can be found S32DS user guide (c:\NXP\S32DS_ARM_v2.2\S32DS\help\pdf\S32DS_ARM_User_Guide.pdf):

Regards,

Lukas

Hi,

something similar was already discussed here:

https://community.nxp.com/t5/S32-SDK/S32K-and-printf-implementation/m-p/867907

I guess this could help.

Regards,

Lukas

Dear Lucas,

Thanks for the information. I notice we need to configure the Libraries support setting to ewl_c no I/O (-specs=ewl_c9x_noio.specs), and there are few options we can select such as newlib_nano no I/O, etc.

Is there doc. to explain the usage for each setting?

Thanks and best regards
