Using the s32K144 chip, during debugging, there is a problem that the ram exceeds 32K and the compilation fails,

According to the specification, the ram of S32K144 is composed of SRAM_L(32K)+SRAM_U(28K)+4K, can I only use SRAM_L when developing?

How can I use the SRAM_U (28K) area. Are there any relevant examples? Thank you!
