shm32 写内部flash之怪现象！

本帖最后由 modu8888 于 2017-7-10 15:36 编辑

   我的产品用在工业上，需保存工作记录。选择使用STM32的内部flash储存——我使用的是较大容量产品STM32F105RBT6,已让记录存储区远离代码区和数据区。考虑到STM32F105RBT6产品内部flash一页的大小为2k字节，加上我的一条记录规划为64字节，我选择在一页中保存32条记录，合计2048字节。
大体上，我预留30页循环存放记录，大致可存近960条。当记录超过后，则覆盖原来的。

现在的问题是，调用库函数写数据有问题。问题如下：
1 调用HAL_FLASH_Program(FLASH_TYPEPROGRAM_HALFWORD, ProgramAddress, (uint64_t)ProgramData)库函数编程有问题——仅能写入首个半字数据，其他半字给我写为0，然而插入一个条件判断则又能正确写入了。反复调试确认了该问题，非常奇怪；
2 刚擦除一页后，写第一条记录，无论如何仅能正确写第一个半字，其他写为0.

具体请看下面代码和我用st Link Utility读出的数据截图。
            i=Cycles%1200;
            ShiftAddress=i*64;
            ShiftAddress=ShiftAddress-64;
            ProgramAddress=0x08011000+ShiftAddress;

            FLASH_EraseInitTypeDef f;
            f.TypeErase = FLASH_TYPEERASE_PAGES;
            f.PageAddress = ProgramAddress;
            f.NbPages = 1;
            if((i-1)%32==0)
            {
                     HAL_FLASH_Unlock();
                     uint32_t PageError = 0;
                     HAL_FLASHEx_Erase(&f, &PageError);
                     HAL_FLASH_Lock();
            }

            HAL_FLASH_Unlock();
            HAL_FLASH_Program(FLASH_TYPEPROGRAM_HALFWORD, ProgramAddress, Cycles);

   运行下面代码，则不是这样：

:o 请问为什么？

modu8888 发表于 2017-7-10 15:41:34

我想应该是写flash的时序问题，也就是HAL库函数的问题。
请有经验的朋友指教哟～

我用hal做过在线升级，编程十几k都没问题呢

谢回复。

我平常写几个字节，都没问题。

结贴了。非HAL库问题！

shuolang126 发表于 2017-7-13 08:29:52

郁闷，结贴了，也不说明问题的原因！

是FreeRTOS的导致出错。系统复位后，创建的信号量的值都自动为1，也就使得我的任务自动执行一次！也就错误的写入一次～
