Position Independent Code for s32k144

stark21 — Thu, 13 Feb 2025 04:14:27 GMT

I have been working on the firmware upgrade process for the S32K144 microcontroller. The memory architecture includes a bootloader and two applications, App1 and App2.

Here is what I have done so far:

App1 is mapped to start at 0x11000 and App2 starts at 0x42000 in the linker file.
I have successfully created individual HEX files for both applications, and they download and jump to their respective addresses (0x11000 for App1 and 0x42000 for App2).

Now I wanted to have position independent code. Could please share the detail documentation and steps to follow in the case of S32DS?

I have reviewed below article but the information provide is limited.

Hi,

PIC has very limited usage on Embedded System without OS. You can find more details here - https://mcuoneclipse.com/2021/06/05/position-independent-code-with-gcc-for-arm-cortex-m/#more-28612

Hi,

Thanks for sharing the information.

The information you have shared is somewhat general and not specific for S32DS and it is surprising that no one from NXP support has tried this PIC feature or have detailed document to use with S32DS.
