问题描述
使用我自己设计的定制板，我无法对 S29GL064S nor Flash 的内容进行编程。我对原理图和布局非常有信心，因为在调用函数时
HAL_nor_Read_ID(&hnor1,&nor_Id)
我得到以下结果
这些值似乎符合 nor Flash 数据表的预期（链接 here）
#define nor_MEMORY_ADRESS1 ((uint32_t)0x60000000)
int main(void)
{
/* USER CODE BEGIN 1 */
uint32_t Address = 0;
uint16_t ReadData = 0;
uint32_t ii=0;
uint16_t WriteData =0;
uint16_t *pWriteData = &WriteData;
uint16_t *pReadData = &ReadData;
uint32_t *pAddress = &Address;

HAL_nor_Read_ID(&hnor1,&nor_Id);
WriteData = 0xbeef;
for(ii=0; ii < 100; ii++)
{
Address = nor_MEMORY_ADRESS1 + ii;
HAL_nor_Program(&hnor1,pAddress,pWriteData);
if(HAL_nor_GetStatus(&hnor1,Address,1000) != HAL_nor_STATUS_SUCCESS)
{
Error_Handler();
}
}

{

/* User can add his own implementation to report the HAL error return state */
while(1)

}
/* USER CODE END Error_Handler_Debug */
}
当我运行这段代码时，以下是我得到的结果：
出于某种原因，我似乎在“数组”的每个单元格中都获得了“ii”的值，而这显然不是我的代码中所要求的。我从来没有设法读回值“0xbeef”。我浏览了“HAL_nor_Program”和“HAL_nor_Read”函数的内容，它们似乎与数据表（表 10.17“命令定义”）中的要求非常一致。
在寻求帮助之前，我真的试图深入了解以确保我做的一切正确，但我真的迷失在这里。有人知道我的代码有什么问题并能帮我修复吗？

我希望它足够清楚，如果您需要更多详细信息，请不要犹豫。
预先感谢您的帮助！
