|
|
|
|
The demo will run on native_sim using the flash simulator.
|
|
|
|
mkdir build; cd build
|
|
cmake -DBOARD=native_sim ..
|
|
make run
|
|
|
|
To test fatfs on MMC, add this cmake option to your build command:
|
|
-DCONF_FILE=prj_mmc.conf
|
|

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
|
|
|
|
Close tests:
|
|
Closed file testfile.txt
|
|
|
|
Delete tests:
|
|
File (testfile.txt) deleted successfully!
