Hey everyone so I just got this today been fiddling around with just the basic stuff, Im about to dive into some more heavy stuff, but before i start I was curious about one thing. So i am also an xbox 360 modder and Id like to jtag my xbox so that I can run homebrew and emulators and develop homebrew and the likes. Now my dillema is i have neither an LPT port nor a USB NAnd flasher like the nand x. Would it be possible to program the Parralel p8x32a propeller quickstart to use the 40 pin serial port to read and Flash the NAND from and Xbox 360. Im not that learned with this at this point to know if its possible or not. Id appreciate it if someone may be able to help me out. The program im trying to interface with can be found here. I basically want to know if i can program it as a nand capture device capable of working with this program. Sorry bout the long crappy explanation to my ?
Heres the program im trying to interface with: http://tech-modz.net/showthread.php?t=331

This is not my guide, i sourced it from elsewhere
So to start you want to get all of your parts together.

After you have got everything in front of you, you can start cutting the tracks on the stripboard ready to solder everything in.
A couple of points.......
I have removed pins from the IC Socket (marked in RED) so there are less tracks to cut (pictured). You can cut tracks instead but that will take alot longer. To remove pins from the socket, hold the tip of your iron on the bottom of the pin while applying a little presure. The pin should just drop out easily.
There is a jumper cable linking pins 8 & 19 on the PIC that can either be connected on the front or the back of the board.
There is also a jumper linking pin 18 on the PIC to ground that needs to be connected to flash the chip (enter bootloader mode) but this must be disconnected to read or write to your nand. You can either solder two wires and connect them when needed or solder a header and use a jumper.
Notice the polarity of the capacitors. If you get polarised capacitors make sure you wire them in right.
Now look at the pictures below to see where everything goes.
R1 = 100Ω RESISTER (Brown Black Brown)
R2 = 10KΩ RESISTOR (Brown Black Orange)
R3 = 100Ω RESISTER (Brown Black Brown)
R4 = 100Ω RESISTER (Brown Black Brown)
R5 = 100Ω RESISTER (Brown Black Brown)
R6 = 100Ω RESISTER (Brown Black Brown)
R7 = 10KΩ RESISTOR (Brown Black Orange)
C1 = 0.1uf CAPACITOR
C2 = 0.22uf CAPACITOR
RZ1 = 12MHZ RESONATOR
thats the USB nand i can make would it be possible to program the propellor to interface the pic so i can flash the .hex files needed to program the pic???

The one other option that is probably available would be to buy something like the ARM-USB-OCD from SparkFun, which the software in the thread you pointed to probably can use, since the ft2232 is a common low-cost JTAG interface, no matter what the target CPU is.
thank you Im going to five the ARM-USB-OCD a try and let you know. I ordered a parralel port today just in case too tho.
