NAND Flash Raw Example

Purpose

This NAND Flash raw example shall show how to read and write data from/to a NAND Flash connected to the chip.

Description

The required steps are:

• Initialize NAND Flash.
• Find a good block by erase function.
• Prepare a buffer.
• Write the buffer into a NAND Flash page data area.
• Read the page and check data is correct.

Usage

1. On the computer, open and configure a terminal application (e.g. HyperTerminal on Microsoft Windows) with these settings:
   • 115200 bauds
   • 8 bits of data
   • No parity
   • 1 stop bit
   • No flow control
2. Start the application.
3. In the terminal window, the following text should appear:

   -- NAND Flash Raw Example --
   -- xxxxxx-xx
   -- Compiled: xxx xx xxxx xx:xx:xx --
   -I- NAND Flash driver initialized
   -I- Size of the whole device in bytes : 0x10000000
   -I- Size in bytes of one single block of a device : 0x20000
   -I- Number of blocks in the entire device : 0x800
   -I- Size of the data area of a page in bytes : 0x800
   -I- Number of pages in the entire device : 0x40
