Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>		2019-04-07 08:45:22 -04:00

Title: Zephyr File System Demo

Description:

Demonstrates basic file and dir operations using the Zephyr file system.
--------------------------------------------------------------------------------

Building and Running Project:

The demo will run on Arduino 101 and will use the on-board SPI flash.

       mkdir build; cd build
       cmake -DBOARD=arduino_101 ..
       make run

--------------------------------------------------------------------------------

Sample Output:

***** BOOTING ZEPHYR OS v1.6.99 - BUILD: Feb  8 2017 07:33:07 *****
Running test suite fat_fs_basic_test

Open tests:
Creating new file testfile.txt
Opened file testfile.txt

Write tests:
Data written:"hello world!"

Data successfully written!

Sync tests:

Read tests:
Data read:"hello world!"

Data read matches data written

Truncate tests:

Testing shrink to 0 size
Testing write after truncating

Write tests:
Data written:"hello world!"

Original size of file = 12

Testing shrinking
File size after shrinking by 5 bytes = 7

Testing expanding
File size after expanding by 10 bytes = 17
Testing for zeroes in expanded region
