If the CPU is ARM does it have JTAG or SWD test access points.

We need a datasheet about the ARM11!

I thought the ARM11 has a JTAG support? How can we dump the NAND, through its pinout yes, but how can we do it exactly? I would like to do some tests on it to see how it works.--Lazymarek9614 23:36, 10 September 2011 (CEST)

The ARM11 IP (intellectual property) has JTAG support, however this port can probably be permanently disabled internally. So there is no way of knowing if this port even still works or exists in the first place.

For dumping NAND, you need to hook up the NAND pins to an FPGA or microcontroller. Then you need to follow the eMMC hardware protocol to read out the data in the various sectors. --Neimod 07:06, 11 September 2011 (CEST)

- Was there data on the raw NAND dumps that wasn't encrypted? Also, was it from a retail unit?

- Are pins exposed underneath the white-banding on the edges of the 3 largest chips? thx Jl12

Are there any photos of the back of the 3DS's PCB? Anything available in a higher resolution (front or back)? Closeups of the SoC and surrounding components (front and back)? Any help greatly appreciated, thanks! --CHR15x94 00:35, 13 September 2011 (CEST)

You could ask the Doctor --Elisherer 19:16, 13 September 2011 (CEST)

Hop... found some. Maybe we should add them to our page? --Elisherer 19:23, 13 September 2011 (CEST)

That's from iFixit, which is already linked to on the page. --Yellows8 20:50, 13 September 2011 (CEST)

Crap, I always manage to miss things like that... >_< Anyway, thanks Elisherer and Yellows8. --CHR15x94 21:11, 13 September 2011 (CEST)

Yes, please add them or replace the existing ones if nesessary.--Lazymarek9614

Hi, My friend, kouchan can't dump the eMMC of his new 3DS. He has already succeeded in dumping old 3DS with the same card reader. Is the pinout of new 3DS really correct?--173210 11:43, 16 April 2015 (CEST)

He finally succeeded. It seems correct.--173210 08:08, 20 April 2015 (CEST)

Are you talking about selling a 3DS version of this? http://home.comcast.net/~olimar/DSCapture/ --MegaByte 05:58, 5 April 2012 (CEST)

L2 cache on O3DS

Is there any L2 cache present on O3Ds at all? The wording "additional 2MB L2 cache" makes it sound like it. If applicable, do we have any idea how big the O3DS's L2 cache is? Neobrain 16:39, 29 September 2015 (CEST)

You are right, there is no L2 cache on the O3DS afaik. Plutooo 16:43, 29 September 2015 (CEST)

Even larger SD cards

I myself can confirm that a 256 GB microSD card works fine within my personal New 3DS XL. The system does take ~25 seconds starting up though (part of this might be me running an emuNAND off it as well). It also takes forever loading large numbers of application tiles. My O3DS also runs a 128 GB microSD, also with an emuNAND, taking about ~20 seconds on boot.
I'm pretty sure the SD card controller can handle even larger SD cards, but I simply don't have larger SD cards to test. I also think each card and each system will react differently to each other, I had the O3DS microSD in my N3DSXL for a long time (also using an emuNAND, it's a lot easier to replace an SD card than a motherboard) and if I remember correctly it also took forever booting up, longer than the O3DS takes right now. https://www.3dbrew.org/wiki/User:Hail
