MCU: STM32H750VB
环境: IAR 9.30.1
内存分配: Flash空间存储代码；ITCM存储关键代码；DTCM存储ReadWrite数据
icf文件配置如下：

但是编译会报链接器错误，不知道什么原因，有大神指点下吗？
[C] 纯文本查看 复制代码 错误：
Warning[Lp051]: some sections in automatic block ".text" would have been placed differently if they were not part of an automatic block. Example: section ".text (msp.o #8)" would have matched "object msp.o section .text" Hat line 75 of "D:\SVN_Project\UAM221\trunk\UAM221_H750VB_APP\EWARM\stm32h750xx_flash.icf"h. Instead, it is placed in block ".text" which matched "rw" Hat line 60 of "D:\SVN_Project\UAM221\trunk\UAM221_H750VB_APP\EWARM\stm32h750xx_flash.icf"h.
Error[Lp008]: ambiguous placement when building the automatic block ".text": member "ro code section .text" matches a different place ("P7" Hat line 67 of "D:\SVN_Project\UAM221\trunk\UAM221_H750VB_APP\EWARM\stm32h750xx_flash.icf"h) than member "rw code section .text" ("P1" Hat line 60 of "D:\SVN_Project\UAM221\trunk\UAM221_H750VB_APP\EWARM\stm32h750xx_flash.icf"h)
Error[Lp005]: placement includes a mix of sections with content (example "ro code section .text in app.o symbols: [app_loop, get_radar_core, app_init]") [suitable for placement in ROM] and sections without content (example "rw code section .text in msp.o symbols: [msp_rangfinder_data_message_encode, crc8_calc, crc8_update]") [suitable for placement in RAM] D:\SVN_Project\UAM221\trunk\UAM221_H750VB_APP\EWARM\stm32h750xx_flash.icf 67
单独用简单的工程使用icf配置是没有问题的，但是结合该工程(源码模块多)就出现上面的报错。

楼主
现在确实还没有弄明白，其中msp.o是一个和其他模块没有关联的程序模块，完全独立的，但编译一直报错。
