How do I put the BSS part of the SRAM in the dtcm

[zenging]

HI，NXP

On the S32K311 chip, I imported a library that took up about 70KB of BSS segment. I would like to ask if there is any way to put the BSS part of SRAM in the dtcm.

We don’t have example code for this specific configuration, but I can offer example code for using DTCM/ITCM memories in the project:

Modification has been done in following files:

- main.c

- startup_cm7.s

- linker_flash_s32k344.ld

Modifying of linker command file in order to put .bss section should not be difficult.
