Accessible from Script nodes usually at:
/media/mmcsd-0-0 - first partition
/media/mmcsd-0-1 - second partition
...
The partition(s) should be pre-formatted as FAT32.
Note the Script node must set: .setProcessor(dai.ProcessorType.LEON_CSS)

An example is added: examples/Script/script_jpeg_to_sdcard.py

  • displays an uncompressed preview stream of RGB camera at 640x360
  • creates a HTTP server listing all files on the first partition of the SDcard
  • when C is pressed, saves a 12MP JPEG capture to SDcard, file names starting from 1000.jpg

When the device is shut down gracefully, the POSIX sync() function is called.
Additionally, an auto-unmount for /media/mmcsd-0-0 is attempted; to succeed, it needs to file or directory handles to be left opened (e.g. os.chdir('/media/mmcsd-0-0') won't allow unmounting).

Related PR: luxonis/depthai-core#293

Note for non-PoE boards (or PoE boards running over USB):

Currently a separate branch is needed: sdcard_no_eth , diff: sdcard_support...sdcard_no_eth
(the HTTP server will not be enbled there)

  /media/mmcsd-0-0    -- first partition
  /media/mmcsd-0-1    -- second partition
  ...

- displays an uncompressed preview stream of RGB camera at 640x360
- creates a HTTP server listing all files on the first partition of the SDcard
- when `C` is pressed, saves a 12MP JPEG capture to SDcard, file names starting from 1000.jpg
No file handles should be left opened for unmount to succeed, not even `os.chdir('/media/mmcsd-0-0')`.
Anyway, a `sync()` is attempted first
