/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)
- 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

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.pyCis pressed, saves a 12MP JPEG capture to SDcard, file names starting from1000.jpgWhen the device is shut down gracefully, the POSIX
sync()function is called.Additionally, an auto-unmount for
/media/mmcsd-0-0is 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)
