将文件系统上传到ESP-WROOM-02

Question

我的项目wit数据包含SSL证书，适合我的测试d1 (ESP8266MOD)板，没有问题。我尝试将相同的系统上传到ESP-WROOM-02系统，但失败并出现错误：

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4mb闪存，而ESP-WROOM-02仅检测2mb。我只在data目录中留下了一个小文件，但仍然得到相同的错误。这是否意味着我根本不能将文件系统上传到我的ESP-WROOM-02？我使用SPIFFS作为文件系统。如何解决这个问题？

根据数据表，ESP-WROOM-02只有2MB闪存。

也许你可以改变你的分区表，为spiff腾出足够的空间。但是，如果您的闪存总需求超过2MB，就没有办法将所有内容都放入内存中。
