将文件系统上传到ESP-WROOM-02

Question

我的包含SSL证书的项目机密数据适合我的测试d1 (ESP8266MOD)板，没有问题。我试图将同一系统上传到ESP-WROOM-02系统，但失败，并显示错误：

A fatal error occurred: File .pio\build\d1\spiffs.bin (length 1024000) at offset 3145728 will not fit in 2097152 bytes of flash. Use --flash-size argument, or change flashing address.

d1 (ESP8266MOD)板自动检测到4mb的闪光，而ESP-WROOM-02仅2mb。我只在data目录中保留了一个小文件，但仍然遇到相同的错误。这是否意味着我根本无法将文件系统上传到我的ESP-WROOM-02？我正在将SPIFFS用于文件系统。如何解决这个问题？

根据数据表，ESP-WROOM-02仅具有2MB闪存。

也许您可以更改分区表以为spiff提供足够的空间。但是，如果您对闪存的总需求超过2MB，则无法将所有内容都放入内存中。
