ESP32S3 片外flash选择有什么限制没有

[sssgil]

ESP32S3 片外flash选择有什么限制没有，比如厂家，flash页大小等，目前开发板工作正常但是自制板子工作不正常，怀疑是不是flash选择有问题

[sssgil]

现在接的是4M的flash，这个会不会有影响我看开发板接的是8M的

[ESP_LJH]

4MB 没有问题的，你用的哪款 flash，现在报什么错？如果把开发板的 flash 放到你的板子上，可以工作起来吗？

[sssgil]

flash用的ZB25VQ32，我仔细看了下开发板的资料，发现不是同一个芯片，开发板是ESP32-S3-USB-OTG内置的8Mflash。问题挺多，之前是无法连接wifi但是开发板可以，然后我增加了一部分功能之后又报如下错误，但是开发板依旧正常。

[ESP_LJH]

可能你的原理图有问题，GPIO45 是不是拉高了，你供电给 flash 的电压可以检查下是不是对的。建议对照硬件设计指南排查下。

[sssgil]

谢谢，检查了遍GPIO45确实拉高了，本来这里的上拉电阻是NC的，但是焊接人员没注意接上了。之前因为VDD_SPI的输出电压不对，所以直接把这里割断拉到3.3V了，这里反复反复操作和焊接估计哪里坏掉了，换了块板子测试正常。至于wifi连不上正在排查其它硬件问题

[ESP_LJH]

wifi 也连不上可能是你射频性能不达标，可以测试下射频的参数。
