双Bank切换图像 二.跳转APP机制 Flash配置为Dual bank mode(DBANK = 1),在Bank1的起始位置(0x0800 0000)放置Bootloader的中断向量表,在Bank2的其实位置(0x0804 0000)放置Bootloader的中断向量表。 正常情况下系统复位时会从Bank1启动,0x0800 0000对应为Bootloader复位向量,首先运行的代码为Bootloader。Bootloader跳转APP...
但这种结构存在的问题也非常巨大,如果用户程序校验异常,则只能停留在Bootloader中,此时MCU无法执行正常的业务。 为了确保正常业务的持续化运行,需要使用具有双Bank Flash结构的MCU。 3、Dual-Bank Flash、具有地址重映射功能的MCU 此类MCU将连续的Flash空间划分为两个Bank,这两个Bank在硬件层面可以独立工作,即某个Bank进...
The dual bank boot is also supported. Each bank contains 256 pages of 2 Kbyte. Flexible protections can be configured thanks to option bytes: • Readout protection (RDP) to protect the whole memory. Three levels are available: – Level 0: no readout protection – Level 1: memory read...

429FLASH为1M, 我想配置为dual bank, 每块512M.设置DB1M成功。现在想擦除dual bank 15 sector, 即#define zaichenxi2018-09-19 09:24:23 剖析STM32的FLASH和SRAM的使用情况 01前言STM32片上自带FLASH和SRAM,简单讲FLASH用来存储程序的,SRAM是用来存储运行程序中的中间变量。本文详细分析下如何查看程序中FLASH和...
可以 改动 FLASH_OPTCR 寄存器的SWAP_BANK 位实现BANK的映射交换, 比较骚操作(不再划分Boot和APP程序, 1MB可以全给应用程序, 直接Bank1运行写新程序到Bank2, 然后Switch到Bank2拷贝BANK2到BANK1, 然后还可以Switch到BANK1运行, 参考AN4767 On-the-fly firmware update for dual bank STM32 microcontrollers), ...
So it has to be related to the Dual Bank configuration done though the option bytes. How do make the JLINK aware of this configuration? I also observed that when I erased the controller through Jlink Commander, it would erase it according to the ...
