when i check the ld file "S32K116_17_flash.ld" i found that the SRAM_U is cut to two area, and i want to know the diff between these two area?

m_data (RW) : ORIGIN = 0x20000000, LENGTH = 0x000020C0
m_data_2 (RW) : ORIGIN = 0x200020C0, LENGTH = 0x00001740

 

file path:

D:\NXP\S32DS_ARM_v2.2\S32DS\software\S32SDK_S32K1xx_RTM_3.0.0\platform\devices\S32K116\linker\gcc

 

thanks

It is specified in linker command file. In can be configured as one area. But consider SRAM_L and SRAM_U are two discontinuous memory spaces.
