Hacking New 3ds and new 3ds xl nand pinouts

[Timburpton]

Has anyone figured out the nand pinouts?

I also have been looking, not found anything yet

Nope.

Someone posted a teardown here: http://garage99.net/blog/new_3ds/

It looks like the test points aren't labeled though, compared to the old 3ds boards.

Should be these. Though it seems like it's missing a pin.
The NAND is 4GB this time btw.

....thats probaby dat0-dat3........actually those 4 points seem to all link up together once they go through the resistor array :S....blah idk

i guess this will be figured out eventually

Yeah those 4 looks like DAT0-DAT3. The one outside should be either CMD or CLK.

Any news on this? Would be nice to be able to got back on my N3DS LL, like I was used to on my 3DS XL. Can post pictures of my own board later, but I don't have a logic analyzer, only a multimeter.

Here are two more pics of the N3DS LL board
EDIT:
Added close-up of what I assume is the NAND chip.

= so n3ds emunand would be/could be 4gb?
i wonder why it is 4gb...

Three and a half gigabytes of copy-protection.

It's actually 2GB. 3dbrew revised that part it seems.

Time to probe some pins with a logic analyzer I guess, I hope the CLK bus isn't on the other side of the board lol.

So this slightly interesting, the US one I have doesn't us a Samsung memory module and no epoxy resin around it either. Also the board is labbed as RED-CPU-01. Though it's highly likely it's pin compatible as everything else looks the same.

Pull ups/downs, the resistors are weak enough to force a 0 or 1 when no data is actually present but strong enough to not cause a short when the line is set to the opposite level

Oh so here, you go this is what I have discovered after a couple hours of tinkering at it. Hope it help those with a N3DS XL
