Position Independent Code in S32ds IDE

Billi2110 — Tue, 18 Feb 2025 10:19:04 GMT

Hi,

Now I am making the sample app for S32k144 and choosing the option Position Independent Code as below the picture

I don't know when I chose it, the app applied PIC or still not and need to choose another option.

and why the *.bin file when I choose PIC has a big mass (~524KB)

Hi @Billi2110 ,

For a better understanding, you can refer the following example on how to create Position Independent Code using the S32DS ARM 2.2 tools: EXAMPLE S32K144 Position Independent Code - NXP Community

Additionally, for detailed information you can consult the following blog: Position-Independent Code with GCC for ARM Cortex-M | MCU on Eclipse

Hi @IsaulO

I fixed this error by using S32k144_64_ram.ld when I built the project. But it still does not define the RAM_START and RAM_END because it is defined in S32k144_64_flash.ld

So how to fix this error?

please help me solve it

Hi @Billi2110,

The project is already set up you just need to change the path for the restore gbd command to your project.bin location (see picExample_Debug_RAM_PNE_fpic Debug configuration) and start a debug session.

Also, if you just want to build the project, you can try selecting the Debug_RAM option.
