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
