可以这样的,不过H750的默认启动地址就是这个,想把程序放到外部运行需要内部的跳转代码的
你要先写个从0x08000000地址跳转到0X90000000地址的程序。MCU上电后默认启动地址0x08000000开始运行。所以你需要2个下载算法以及flash地址分配。
The BOOT_ADD0 and BOOT_ADD1 address option bytes allows to program any boot memory address from 0x0000 0000 to 0x3FFF 0000 which includes:
1、All Flash address space
2、All RAM address space: ITCM, DTCM RAMs and SRAMs
3、The TCM-RAM
The BOOT_ADD0 / BOOT_ADD1 option bytes can be modified after reset in order to boot from any other boot address after next reset. If the programmed boot memory address is out of the memory mapped area or a reserved area, the default boot fetch address is programmed as follows:
1、Boot address 0: FLASH at 0x0800 0000
2、Boot address 1: ITCM-RAM at 0x0000 0000
