embedded studio ram debug 进入hardfault

Superusrss

使用stm32h750芯片，ram比flash大，所以使用ram调试

在embedded studio中设置好__VECTORS_IN_RAM，改好memory map后编译会发现中断向量表在设置的地方，boot地址也设置了，但是进调试就hardfault。同样的工程不改 memory map和vectable没有问题，相同操作在f4上面也没有问题，看上去像是segger做了初始化后就fault了，

大家知道原因吗？大工程MDK太慢了，而且老是触发全编译（5.39每次都是全编译，服了）

帮顶，没用SES测试过RAM调试。

Superusrss

update:
system_stm32h7xx.c 文件中有这么一句：

/************************* Miscellaneous Configuration ************************/
/*!< Uncomment the following line if you need to use initialized data in D2 domain SRAM (AHB SRAM) */
/* #define DATA_IN_D2_SRAM */
/*!< Uncomment the following line if you need to relocate your vector Table in
     Internal SRAM. */

默认编译有部分内存用到d2域的sram，没有开时钟会卡在init。不过开了时钟会进hardfault
