ld link file to do partition modification

HI,NXP

I would like to ask how to do the correct partition modification, because I tried to re-partition the memory by modifying the ld file, but when I finished the modification to compile. A hard error message is displayed.

Hi @zenging,

What modification have you made in the linker file?

HI@danielmartynek

This is the original default link file, because the SRAM of s32K311 is 32KB by default, and the underlying library I used here is about 70KB, which is obviously not enough. Therefore, my original practice is to free up the memory size of dtcm for expanding sram, but it will cause hard failure. Would like to ask if there is any way to make the dtcm section of memory and sram together

Hi @zenging,

DTCM and SRAM cannot be in one section.

These are different memories, mapped to different addresses.

Daniel

Hi，@danielmartynek

So is there any other solution, because the library file I imported is too large.

This example shows how to place functions into ITCM and data into DTCM:
