SFUD W25Q64BV Write Enable Failed

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！

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 rt_hw_spi_device_attach 函数添加 SPI 设备时配置，如果在 CubeMX 中配置了可能反而会导致报错。

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。

打不开关不上，然后挂载文件系统是报的是格式不正确，应该 W25Q16DVSIG 是支持的吧

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
