3.2.1 Use of NAND Flash (RCM4000 only)
The following sample programs can be found in the SAMPLES\RCM4000\NANDFlash folder.

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.
This log can be viewed and cleared from a browser by connecting the RJ-45 jack on the
RCM4000 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.
