STM32F746程序镜像大于1MB时，同时使用IROM1和IROM2下载失败是为什么？

问答对人有帮助，内容完整，我也想知道答案 0 您好，我的应用程序大于1MB后，勾选IROM2后，下载失败，提示：Load linking...Program Size: Code=225528 RO-data=866252 RW-data=188 ZI-data=223420 ".Objectslv_f746.axf" - 0 Error(s), 0 Warning(s).

答案对人有帮助，有参考价值 0 手册上看STM32F746最大的容量是1M哦，所以代码超过该型号容量，编译器会限制的。

答案对人有帮助，有参考价值 0 这个问题可能是由于你的芯片的存储器不能同时使用IROM1和IROM2引起的。STM32F746芯片的IROM1区域大小为496KB，IROM2区域大小为512KB，总共只有1MB的Flash可用。当你的应用程序大于1MB时，就无法同时将其编译进IROM1和IROM2区域。解决这个问题的方法是，将你的应用程序编译进IROM1区域，然后使用外部存储器，比如SD卡或者外部Flash，来存储额外的数据或者代码。你可以使用SD卡接口或者外部存储器接口来读取这些数据或者代码，并在运行时加载到RAM中。你还需要在链接器脚本或者工程设置中指定正确的存储器映射，以确保编译器正确地将代码和数据放置在正确的存储器区域。如果你对如何配置存储器映射不确定，建议你参考ST官方的文档或者开发板的参考手册，以获取更详细的指导。
