关于qspi w25q16下载算法的问题

1035916571

请问一下，使用v7的mdk下载算法例程修改后下载成功擦除也是成功的，并且把qspi里的内存读出来和原始文件对比都是相同的，但是在校验过程中失败，我看论坛也有人出现相似的问题，想问下有没有解决办法

看下你的算法使用的那种时钟方式，改成使用内部RC试试，部分坛友使用这个方法后解决了。

提示这个，这个是校验失败，你看下你的内存映射实现是不是还有问题，因为我那个例子，读取是直接配置成内存映射模式了。

如果你确认你的没问题，可以添加校验函数，并字节返回成功。

已解决，是因为下载算法例程的4字节读取寄存器0xec的宏有两个相同的，我只改了一个，但是另外一个没改，现在改成0xeb是正常的。
