Figure 14. Insertion/Removal of microSD Card
Rabbit Semiconductor recommends that you use the microSD Card holder at header J3
only for the microSD Card since other devices are not supported. Be careful to remove
and insert the card as shown, and be careful not to insert any foreign objects, which may
short out the contacts and lead to the destruction of your card.
It is possible to hot-swap microSD Cards without removing power from the RCM4300
modules. The file system must be closed before the cards can be hot-swapped. The chip
selects associated with the card must be set to their inactive state, and read/write opera-
tions addressed to the microSD Card port cannot be allowed to occur. These operations
can be initiated in software by sensing an external switch actuated by the user, and the
card can then be removed and replaced with a different one. Once the application program
detects a new card, the file system can be opened. These steps allow the microSD Card
to be installed or removed without affecting either the program, which continues to run on
the RCM4300 module, or the data stored on the card. The Dynamic C FAT file system will
handle this overhead automatically by unmounting the microSD Card. LED DS4 above
the microSD Card is used by the FAT file system to show when the media is mounted.
Standard Windows SD Card readers may be used to read the microSD Card formatted
by the Dynamic C FAT file system with the RCM4300 as long as it has not been parti-
tioned. An SD Card adapter is included with the microSD Card in the in the RCM4300
Development Kit. The SD Card adapter has a sliding switch along the left side that may be
moved down to write-protect the microSD Card while it is being used with an SD Card
reader.
Sample programs in the SAMPLES\RCM4300\SD_Flash folder illustrate the use of the
microSD Cards. These sample programs are described in Section 3.2.2, “Use of
