S32K322 memory overflow

user01 — Mon, 11 Aug 2025 04:05:51 GMT

Hello:

I have encountered some issues while using the S32K322 chip recently. The specific problems are as follows:

(Development Platform: S32DS. 3.6.2 Chip model: S32K322)

The program reported an error during compilation:

So I modified the size of int_stram_c0 in Project_Settings ->Linker_Files ->linker_flash_c0us32k322.ld
Before modification：

After modification：

After recompiling, there are no errors reported：

But when I was debugging, the program got stuck in SRAM_LOOP in Project_Settings ->Startup_Cde ->startup_cm7. s:
SRAM_LOOP:
strd r0, r1, [r2], #8
cmp r2, r3
blt SRAM_LOOP
SRAM_LOOP_END:

This problem has been bothering me for a long time, but I have not been able to solve it. Now I need your help to provide an effective solution. Thank you very much!

Hi @user01,

Can you open the core register view and check the values in R2 and R3.

ldr r2, =__INT_SRAM_START (int_sram_c0)
ldr r3, =__INT_SRAM_END (ram_end_c0)

R2 is the start address of the SRAM region.

The loop is incrementing R2 by 8 bytes each iteration until R2 is equal to R3.

Thank you,

BR, Daniel
