NAND Flash Boot: NAND Flash Detection
The sixth vector, at offset 0x14, contains the size of the image to download. The user must
replace this vector with the user’s own vector. This information is described below.
Figure 11-7. Structure of the ARM Vector 6
The value has to be smaller than 24 kbytes. This size is the internal SRAM size minus the stack
size used by the ROM Code at the end of the internal SRAM.
An example of valid vectors follows:
This method is the one used on FAT formatted SDCard. The boot program must be a file named
“boot.bin” written in the root directory of the filesystem. Its size must not exceed the maximum
size allowed: 24 kbytes (0x6000).
After NAND Flash interface configuration, a reset command is sent to the memory.
The Boot Program first tries to find valid software on a NAND Flash device connected to
EBI CS3, with data lines connected to D0-D7, then on NAND Flash connected to D16-D23.
Hardware ECC detection and correction are provided by the PMECC peripheral (refer to the
PMECC section in the datasheet for more information).
The Boot Program is able to retrieve NAND Flash parameters and ECC requirements using two
methods as follows:
or

• the detection of a specific header written at the beginning of the first page of NAND Flash,
• through the ONFI parameters for ONFI compliant memories.
