My project wit data that contains SSL certificate fits to my test d1 (ESP8266MOD) board that without problems. I tried to upload the same system to ESP-WROOM-02 system and it failed with error:
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) board autodetects 4mb flash while ESP-WROOM-02 only 2mb. I left only one small file, in data directory, but still got the same error. Does it mean I can't upload file system to my ESP-WROOM-02 at all? I'm using SPIFFS for file system. How to solve this problem?
