- The 120MHz FPU 1M parts have 4k Flash sector size and don't support the long word programming command but instead the "phrase" programming command (8 bytes) However I don't find the sector size specified in either the user manual or the data sheets (apart from some timing which have...
Hello ! I can see flash memory sector size is 32KB and that size is used for define secure access rules and some ROM API is use that size in Erase
这里一开始就改过的，我现在是 FLASH_SECTOR_SIZE = 4096 FLASH_SETOR_COUNT = 1024， min_sector ...

One example are STM32F2, STM32F4 and STM32F7 series which have variable sector size. On these series, erase-block-size depends on sector size and then cannot be defined as done usually in flash controller parent. Check should have a fallback for this case....
以stm32f103cbt6为例,flash起始地址为0x8000000,大小是0x20000。一个Sector的大小是1K。那么定义参数位置如下: #definePARA_START_ADDR((u32)0x0801fc00)#definePARA_PAGE_SIZE((u16)0x400) 03 参数形式 将参数封装成一个结构体,方便读存。注意flash存储时会自动做4字节对齐,所有尽量保证PARASAVED_T的大小是4的...
