S32K314's SRAM is overflow

[shunyizhang]

Hi,@NXP

Appears when compiling a project with S32DS for S32 platform“Description Resource Path Location Type
Ld error: region `int_sram' overflowed by 417616 bytes S32K314OFBCU C/C++ Problem(IC S32K314)”

.ld

HEAP_SIZE = DEFINED(__heap_size__) ? __heap_size__ : 0x00002000;
__STANDBY_RAM_LIMIT_END = 0x20407FFF; /* 32Kbyte for standby ram */

ENTRY(Reset_Handler)

ram_rsvd2 : ORIGIN = 0x20444000, LENGTH = 0 /* End of SRAM */
}

How should I modify this ld file, please give an example and list the modification process, thank you!

Hi@shunyizhang

In your link file, the SRAM space has been fully used and exceeds 417616 bytes. This number is far beyond our SRAM space. This is not a problem that can be solved by modifying the link file. You should check the space occupied by your application code.
