Hello,
When we used (RT1060) freertos+lwip+sdmmc+fatfs and many other features, we encountered a problem.
As follows:
1、Based on SDK_2.6.2_EVK-MIMXRT1060.
2、When I choose not to use optimization:
3、optinos use $PROJ_DIR$\MIMXRT1062xxxxx_ram.icf：
define symbol m_interrupts_start = 0x00000000;
define symbol m_interrupts_end = 0x000003FF;
define symbol m_text_start = 0x00000400;
define symbol m_text_end = 0x0001FFFF;
define symbol m_data_start = 0x20000000;
define symbol m_data_end = 0x2001FFFF;
define symbol m_data2_start = 0x20200000;
define symbol m_data2_end = 0x202BFFFF;
4、IAR compilation ram result:
122 737 bytes of readonly code memory
22 331 bytes of readonly data memory
87 615 bytes of readwrite data memory
5、error：IAR compilation fails and can only be passed when optimization is used.
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).
6、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)
7、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?
Thank you very mach.
