程序溢出：nable to allocate space for sections/blocks with a total estimated minimum size of 0x2’32ac bytes (max align 0x8) in <[0x0-0x3ff], [0x400-0x1’ffff]> (total uncommitted space 0x1’fc00)

第一次开始分享，加油。

When we used freertos+lwip+sdmmc+fatfs and many other features in RT1050, we encountered a problem.
As follows:
1、Based on SDK_2.6.2_EVK-MIMXRT1060.
2、When I choose not to use optimization:

2、optinos use MIMXRT1062xxxxx_ram.icf：

3、IAR compilation ram result:
unable to allocate space for sections/blocks with a total estimated minimum size of 0x2’32ac bytes (max align 0x8) in <[0x0-0x3ff], [0x400-0x1’ffff]> (total uncommitted space 0x1’fc00).

4、error：IAR compilation fails and can only be passed when optimization is used.

5、The project size now does not exceed the memory of RT1060:
1）RT1060：1MB On-Chip SRAM - up to 512KB configurable as Tightly Coupled Memory (TCM)
6、question：
1）Why is this problem? --------------nable to allocate space for sections/blocks with a total estimated minimum size of 0x2’32ac bytes (max align 0x8) in <[0x0-0x3ff], [0x400-0x1’ffff]> (total uncommitted space 0x1’fc00).
2）How to solve the problem of iar compilation failure?
3）Do you have any better suggestions?
7、Solution：
1）Modify the MIMXRT1062xxxxx_ram.icf file

2）run OK.
