So, i am able to dump my NOR thanks to judges and defyboy. Weird thing is every dump is 15.9mb and never a true 16mb file. Keep in mind I am testing this on a RSOD console. No two files are the same size but always about 50,000 bytes short (more or less) of 16mb. Hmm...

also with the 360 (not sure about ps3)
if you power on in between it will change the dump, but different file sizes...yeah bad wiring id imagine

Alright did some more dump tests. The previous dumps that weren't matching up were done with the console on in factory/service mode. I then put the console back to retail with "Lv2diag.self FILE 2" and now multiple dumps match but are still short by 20,000 bytes to complete the full 16mb. Wiring matches the source and I have checked the physical wiring many times both on the teensy as well as the motherboard and everything checks out. Here is the source code used NOR read.rar if anyone would like to take a look at it. Pictures of the pinout for motherboard to teensy that I used can be found on page 14.

Again this testing is done on a RSOD console so those last missing 20,000 bytes might be the cause. I am hoping someone with the same motherboard is working on this as well, as I would like to confirm the source code/wiring is working properly.

i was under the assumption that it needs dumped while in standby

I have tried dumping while it is off, standby, and powered. Powered on seems to give me the somewhat proper dump whereas in standby or off I get one long line of "ÿ"

All data is dumped as raw

Hey everyone I started a new thread for just the NOR and Teensy++ 2.0 discussion

Make sure you are supplying sufficient power, make sure you have it grounded and are using the correct tristate point.

The 3.3v regulator on the Teensy does not have nearly enough power to supply the console. USB port will only supply max 500ma, the 3.3v regulator is rated at 500ma but the console will draw about 1.7a, it will overheat the regulator and underpower the console. Disconnect 3.3v from your teensy to the PS3 motherboard and only use the consoles internal power.

I am getting closer to releasing the newest iteration of ATNORFLASH along with the PC-side application.

I see your dumps were a bit short, It might pay to look at the source here:

		for(int x=0; x<=0x7F; x++) {
			for(int y=0; y<=0xFF; y++) {
				for(int z=0; z<=0xFF; z++) {
					ADDR3_PORT = x;
					ADDR2_PORT = y;
					ADDR1_PORT = z;
					__asm__ volatile ("nop");
					__asm__ volatile ("nop");
					usb_serial_putchar(DATA2_PIN);
					usb_serial_putchar(DATA1_PIN);
				}
			}
		}

The loops look incorrect, try:

		for(int x=0; x==0x7F; x++) {
			for(int y=0; y==0xFF; y++) {
				for(int z=0; z==0xFF; z++) {

That should add a bit of data you are missing.

Again, this source was not ready for the primetime, don't expect it to work properly

Thanks for the update. As far as power to the teensy goes, I have already removed the 3.3 voltage regulator with the 5 volt trace cut, but I do still short out the 3 volt pads correct?

I appreciate it. I'll give it a try in the meantime while waiting for you updated work.

One question though. On your board you have a separate WP test point where as on my mobo it is tied to VCC. How would I go about wiring that point to the teensy?

So are you guys cutting the power cable in the usb cable? and just using the power from the Playstation?

We all are pulling for ya! Just let us know if you need anything or have us test things for you.
