Download NandPro Use this for reading and writing the on board 360 NAND.

Also be sure to check that your read is a valid bin. Read it twice just to be sure.
LPC2148 Olimex USB header board
High performance 16MB/2Mins
Parallel Printer Port, SPP mode
Low performance, 16MB/35mins (cpu dependant)
Dlportio printer port driver
Seven connections must be made from MAINBRD to the HW device interface.
MAINBRD connects as specified to either Olimex board, or a PC printer port.
ArmLpc Olimex LPT MAINBRD
SS EXT1-3 DB25.1 J1D2.2
MISO EXT1-6 DB25.11 J1D2.4
P0.28 EXT2-1 DB25.16 J2B1.6
GND EXT1-26 DB25.18 J1D2.6 or J2B1.12
MOSI EXT1-7 DB25.14 J1D2.1
SCK EXT1-5 DB25.2 J1D2.3
P0.29 EXT2-2 DB25.17 J2B1.5
Flash the .hex file to the LPC2148.
Connect LPC2148 to computer USB.
Point "found new hardware" to the "custom.inf"
Windows reports: "Your new hardware is ready to use"
Some parallel ports run at 3.3v others at 5v. The MAINBRD is 3.3 volts.
Testing with 5 volt lpt and NO resistors didn't burn anything up. YMMV
It is recomnened to use 100 ohm series resistors
for all lpt connections except for DB25.11 and DB25.18 (GND).
This solution isn't perfect but you typically dont leave it hooked up forever anyway.
If someone wants to design and post a buffer circuit go right ahead. I can't be bothered
Run the port95nt.exe application to install the DlPortio driver
Make connections to MAINBRD and run the app.
MAINBRD needs to be plugged in to AC power.
Actually powered on or not does not matter.
While running NandPro application reset will occur.
After nand operation is complete, reset will be released.
Typical command line:
Read entire 16M flash, including ECC:
NandPro lpt: -r16 nand.bin
Write entire 16M flash, including ECC:
NandPro lpt: -w16 nand.bin
READING WILL OVER-WRITE AN EXISTING FILE WITHOUT WARNING!
NEW LOG FILE WILL OVERWRITE OLD WITHOUT WARNING!
Edit: If you encounter problems when using the LPT interface as shown above, please refer to this post.
