Overview

Note

This example uses file system with SD to write to and read from an SD card using ADMA2 in polled mode. To test this example File System should not be in Read Only mode. To test this example USE_MKFS option should be true.

This example was tested using SD2.0 card and eMMC (using eMMC to SD adaptor).

To test with different logical drives, drive number should be mentioned in both FileName and Path variables. By default, it will take drive 0 if drive number is not mentioned in the FileName variable. For example, to test logical drive 1 FileName = "1:/<file_name>" and Path = "1:/" Similarly to test logical drive N, FileName = "N:/<file_name>" and Path = "N:/"

None.
