Huge littlefs.bin file

Hi,

When I m trying to upload file system image (Data folder) to Wemos d1 mini pro board the generated image file (littlefs.bin) is huge. More than 4gb and of course I m getting ERR: ERROR[4]: Not Enough Space. On Wemos d1 mini board everything working fine.

I checked it in Vscode macOs Catalina (pio core 4.4.0b1 and 4.3.4), Ubuntu desktop 20.04.1 LTS Vscode (pio core 4.3.4), Ubuntu server 18.04.4 LTS (pio core 4.3.4) and Win 10 Vscode (pio core 4.3.4).

Platformio.ini:

[platformio]
default_envs = d1_mini_pro

[env]
platform = espressif8266
framework = arduino
board_build.filesystem = littlefs
monitor_speed = 115200
upload_protocol = espota
upload_port = 10.0.0.35
lib_deps = 
	ESPAsyncTCP
	ESP Async WebServer

[env:d1_mini]
board = d1_mini

[env:d1_mini_pro]
board = d1_mini_pro

And my logs in both cases:

Thank you.

Now that’s a really large number, 4GB minus 2072 kilobytes. It reminds me of issue https://github.com/platformio/platform-espressif8266/issues/190 which however occured with SPIFFS but with the same d1_mini_pro board. The size calculation code may have been copy-pated from the SPIFFS version and still exhibit the same bug though.

Workaround may still be valid by forcing the usage of only 8MB of flash of which 7MB is the filesystem.

board_build.ldscript = eagle.flash.8m7m.ld

@valeros could you have a look at this?

Yes, this workaround is still valid.

Thanks @maxgerhardt !
