大家好，
我正在尝试用STM32F1的FLASH编写程序，但是由于某种原因它无法正常工作……每当我编写某些程序时，它都会返回错误：HAL_FLASH_ERROR_PROG，这是编程错误。当我在闪存状态寄存器中查看它时，它的意思是：当要编程的地址包含一个与编程前的“ 0xFFFF”不同的值时，由硬件进行设置。
然后当我解析到STM32F1的FLASH存储器中时，我看到从0x801EC00到0x801F17F的内存范围为0x0000。因此，编程错误。
我不明白的是为什么没有删除存储器的这一部分。这是我的代码：
/* Specify the memory areas */
MEMORY

RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 20K
FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 128K - 5K
Erases (RW) : ORIGIN = 0x801EC00, LENGTH = 4
Frames (RW) : ORIGIN = 0x801EC04, LENGTH = 4

FRAMESRx (RW) : ORIGIN = 0x801F180, LENGTH = 1800
FRAMESADC(RW) : ORIGIN = 0x801F888, LENGTH = 800
FRAMESOP (RW) : ORIGIN = 0x801FBA8, LENGTH = 800
}

函数“ Saving_Flash”是我在main.c中调用的函数，用于将CAN_Tab_TxMessages保存在FLASH中。 Flash_writepreparation（）应该准备好要写入的Flash（解锁，擦除5页，清除标志）。最后，Flash_CANTx_write将数组的每一帧写入FLASH。
如果您对为什么HAL_FLASHEx_Erase（）无法正常工作有任何想法...
只需添加：构建代码时就没有特殊的警告或错误。
提前谢谢！
EDIT：我试图更改FLASH_CANTx_Write中的HAL_FLASH_Program的地址，以将＆CAN_Tab_RxMessages_Flash放入内存缓冲区中，从0x801F180到0x801F888等于00000000。因此，根据我要写入的位置，地址无法正确删除...但是我不知道该如何处理..
