K22 RAM分配问题

[liubinc]

MCU:MK22FN512

RAM大小：两个64K组成128KB

问题：

程序中开辟了很多全局数组，如：

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

IAR编译链接OK后，出来的RAM空间6K readony data memory；70K readwrite data memory；

然后我再开辟一个全局数据 static double total_tem_data_x[128];128个double也才1K，加上之前的6K和70K也才77K的总大小。

编译链接后就报错了

Hello Liubin,

You can try to declare  the SRAM as one "single" area instead two parts.

Please refer to this thread :

Help me out of this IAR compile Error : cannot fit "Block .bss"   

Hope it helps

Have a great day,
TIC
