我们知道,Flash在写的时候必须先整块Sector擦除才能写入。F0/F1系列的直接调用函数擦除指定地址的Sector就行,比如我们需要擦除0x08000000起始地址的Sector,程序如下: FLASH_EraseInitTypeDef f; f.TypeErase = FLASH_TYPEERASE_PAGES; f.PageAddress = 0x08000000; f.NbPages = 1; PageError = 0; HAL_FLASH_Unl...
编程方式是直接对FLASH进行底层的读写操作,需要对相关寄存器进行配置和控制。 1.写入数据 在STM32的FLASH中写入数据的操作需要经历以下步骤: 1) 解锁FLASH:通过FLASH_Unlock(函数解锁FLASH,使其可写入。 2) 擦除FLASH:通过FLASH_ErasePage(函数擦除要写入的FLASH扇区。 3) 写入数据:通过FLASH_ProgramByte(、FLASH_...

We are currently working with a new STM32F4 chip with the following internal flash and Ram address: iROM - Starting address: 0x00000000, Size = 1M bytes iRAM - Starting address: 0x20000000, Size = 128K bytes So far we have not been able to transfer…
STM32 Flash执行速度:ST系统频次不访问flash等待时长关系,0等待周期,当0<>z;1等待周期,当24MHz<>K≤48MHz;2等待周期,当48MHz<>K≤72MHz。 Flash擦除时长:GD擦除的时长要久一点,官方给出的数据是这样的“GD32F103/101系列Flash 128KB及以下的型号,Page Erase典型值100ms,实际测量60ms左右。”对应的ST...
