My SRAM_U too small, I want to combine SRAM_L&SRAM_U.
Is it possible and are there any limit?
/* SRAM_L */
m_data (RW) : ORIGIN = 0x1FFF8000, LENGTH = 0x00008000
/* SRAM_U */
m_data_2 (RW) : ORIGIN = 0x20000000, LENGTH = 0x00007000
I've seen some internal discussions on this issue and their answer is no, you can't combine SRAM_L & SRAM_U.
you can take a look at this discussions as below.

PS:
The SRAM of the S32K14x series MCU consists of two areas: SRAM_L and SRAM_U. The SRAM_L area is accessed through the Code Bus bus of the ARM CM4F core, while the SRAM_ area is accessed through the System Bus bus of the ARM CM4F core.
