Basic IFS

Simple Webserver demonstration using IFS.

View the filesystem using a web browser.

To see directory content in a different format, append ?format=XX, one of:

  • json

  • text

  • html

Use the format archive to retrieve an archive/backup of the directory tree as an FWFS image.


By default, data is stored in a read-only FWFS (Firmware Filesytem) partition.

This sample also demonstrates how to store the data in a FlashString object:

make config-clean

Because the data is linked into the program image this is only suitable for small filesystem images. This could be used to store default recovery data, especially with OTA updates because each program image is self-contained.
