I can't seem to convince the linker to use the section SRAM_LOWER. It overflows SRAM_UPPER without adding anything to the lower section.
Memory region Used Size Region Size %age Used
SRAM_UPPER: 262116 B 192 KB 133.32%

c:/nxp/mcuxpressoide_10.1.1_606/ide/tools/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/bin/ld.exe: rtcpu16 Foundation.axf section `.bss' will not fit in region `SRAM_UPPER'
FLEX_RAM: 0 GB 4 KB 0.00%
How do I utilize this memory?
