这是我的ICF文件,因为外部扩展了2M的SRAM,问题是编译器将堆栈自动放在了外部SRAM,这样程序启动时外部端口还没有初始化根本读写不了RAM,造成启动失败。假如改成这样
define symbol __ICFEDIT_region_RAM_end__ = 0x680FFFFF;
define region RAM_region = mem:[from 0x20000000 to 0x680fffff]-mem:[from 0x20020000 to 0x68000000];
只使用1M sram,就会自动将堆栈放在芯片的内部RAM中,这样就完全没问题。
如何设置将CSTACK强制放在内部ram中?
