W25Q64BV Write Enable Failed #34

您好这个我测试了，没有问题。可能代码移植有问题，建议用逻辑分析仪查一下波形 |
|
很可能是CS脚没有配置对！ |
|
不需要在 CubeMX 中配置片选引脚，片选引脚会在后面使用 |

这个可能与spi的驱动有关系，我也遇到过类似的，但后来发现是多个SPI读写切换引起，切换后需要重新重新初始化SPI发自我的手机-------- 原始邮件 --------发件人： ThinkCode ***@***.***>日期： 2022年9月22日周四 11:15收件人： armink/SFUD ***@***.***>抄送： Subscribed ***@***.***>主 题： Re: [armink/SFUD] W25Q64BV Write Enable Failed (#34)

那我要把flash挂载文件系统，这个怎么重新初始化。我测试过确实有的时候好，有的时候不能用。用sf工具读没有问题，但写和擦除时好时坏。 |

我测试过，好像写状态试能的问题 msh />sf bench yes

我又尝试了战舰V3上的W25Q128JV 没有出现这个问题，使用正常，能成功挂载为文件系统。 |
|
我给我F407的板子也换上了W25Q128JV,依然有问题 |
|
/**
// if (result == SFUD_SUCCESS) { 如果实在找不到办法，可以在sfud.c中屏蔽掉读写状态位判断就能正常读写了 |

借用https://blog.csdn.net/p1279030826/article/details/107334427，这个作者的方法做如下两点修改： 最终串口打印结果为： [11:29:41.307]收←◆繱FUD](......\sfud\src\sfud.c:116) Start initialize Serial Flash Universal Driver(SFUD) V1.1.0.

使用其他的F407测试, 没有出现这个问题, 果然便宜没好货, 这个单片机可能是翻新的或是拆机的, 现在已经坏了写不进去程序了. |
你好，你的工具设计很不错，我尝试了下，修改def为winbod W25Q64BV，运行后发现在
“sfud_erase”中执行write enable报错，但我用其它驱动读写都没问题，说明板子是可以write enable的，看你的代码中有lock spi 然后unlock spi这个动作，不太明白为什么需要，也不清楚为什么Status Register的WEL位没有置1，请问可以帮我看看么，谢谢！
