In the default linker files the RAM is broken into 2 different segments SRAM_L and SRAM_U. For example on the S32k144
/* SRAM_L */
m_data (RW) : ORIGIN = 0x1FFF8000, LENGTH = 0x00008000
/* SRAM_U */
m_data_2 (RW) : ORIGIN = 0x20000000, LENGTH = 0x00007000
The addressing is continuous so is it OK to combine these or is there a good reason to keep them split. For example can I do the following?
/* SRAM */
m_data (RW) : ORIGIN = 0x1FFF8000, LENGTH = 0x0000F000
