supplementary information:

1. I have happened to succeeded to flash file system to esp-box for just only once.
2. It always failed to "idf.py storage-flash" or write file system "storage.bin" by "esptool.py"
3. It normally succeeded to "idf.py flash" to write bootloader or other binary

reproduce of this error.

[donghengqaz]

This is related to issue:espressif/esptool#795, I have fix this by reducing file-system image size.

Note: reduction to less than 16MB flash use is not a fix, only a workaround. For devices using 32MB flash, this workaround artificially limits the device to using <16MB of the flash.

Yes, this is a workaround, and I am waiting for esptool maintainer to fix this, firstly I try to let users of this SDK feel smooth to flash image.

I think it's fixed (since this commit, so you can probably restore the expected partition here).
