About MK22 RAM

Hi, all.

I am using MK22FN512 in my project, IAR IDE.

I defined many arrays in my code. such as:

static double total_tem_data_y[128*8];
static double total_tem_data_z[128*8];

According to the link message, my project used about 70K bytes data memory.

when I defined one more array about 1K bytes, it doesn't work.

The IAR link massage show in figure.

My question:the RAM is not enough? but there are 128K bytes RAM in The MCU.

Look forward to your soonest reply.
