3.2.1 Use of NAND Flash
The following sample programs can be found in the SAMPLES\RCM3360\NANDFlash folder.
As you run most of these sample programs, you will be prompted in the Dynamic C STDIO win-
dow to select either the
xD-Picture Card (0 = soldered, 1 = socketed).

User’s Manual
NFLASH_DUMP.c
NAND flash chip to the Dynamic C
rected to a serial port.
When the sample program starts running, it attempts to communicate with the user-
selected NAND flash chip. If this communication is successful and the main page size
is acceptable, the nonerased page contents (non 0xFF) from the NAND flash page are
dumped to the Dynamic C
Note that an error message might appear when the first 32 pages (0x20 pages) are
“dumped.” You may ignore the error message.
NFLASH_INSPECT.c
NAND flash chip. When the sample program starts running, it attempts to communi-
cate with the NAND flash chip selected by the user. Once a NAND flash chip is found,
the user can execute various commands to print out the contents of a specified page,
clear (set to zero) all the bytes in a specified page, erase (set to FF), or write to specified
pages.
NFLASH_LOG.c
the NAND flash. As long as the xD-Picture Card is plugged in to its connector J6, this
sample program will log hits to the xD-Picture Card. Remove the xD-Picture Card if
you wish to log hits on the soldered-in NAND flash (RCM3365 model only).
This log can be viewed and cleared from a browser by connecting the RJ-45 jack on the
RCM3365 to your PC as described in Section 6.1. The sidebar on the next page
explains how to set up your PC or notebook to view this log.
CAUTION: When you run this sample program, enabling the #define NFLASH_
CANERASEBADBLOCKS macro makes it possible to write to bad blocks. The first two
blocks on the xD-Picture Card are marked bad to protect the configuration data needed
to use the card in a digital camera or a PC. You will only be able to use the xD-Picture
Card in Rabbit-based systems if either of the first two blocks is written to.
