Hacking Some new information that hints about Mariko

[delete12345]

5.0.0 included hw bringup for a new SoC called Mariko. nvidia calls it t214 (it's a fork of tegra X1), it has a custom nintendo bootrom, new key material, new pmic (and new pcb!). however it will probably look identical from outside ;) @hexkyz

Found very strong evidence of a whole new PCB and 8GB memory for new T214 Switch (Mariko):https://t.co/qGRBeDB5mf

Oh, right, I should've clarified this better. The strongest evidence for a new PCB is the added support for a new PMIC in PCV sysmodule (max77621 will be replaced by max77812).

Sounds good. :)
They still call the retail board "nx-abca2" though, so nothing is certain at this point.

Indeed, I suspect the RAM upgrade should be for devkits only (at least for now).

Dev for new products begins immediately after the product releases, if not before. Nintendo was working on the n3ds as soon as the o3ds was out the door. It's standard product dev cycle, we've just never had a foothold in the system this early to witness it.

Interesting fact: Tegra systems are code-named after Marvel characters. TK1 was "Logan", TX1 was "Erista" and now T214 SoC's name "Mariko" comes from Mariko Yashida, Wolverine's lover. Whether this symbolizes Nvidia and Nintendo's scorching "romance" remains to be seen. ;)

That's all.

Does it mean a new Hardware Revision?

Maybe, maybe not. Only time (and hackers) can tell.

Hmmmm, I wonder if they will keep the 8gb memory just for the devs like what they were saying or if they will use this to incentivize people to get new switches with "faster" capabilities. But this would likely also piss people off, especially if newer games started having much more noticeable differences or complete incompatibility. It's going to be interesting to see how this develops.

Time for New Nintendo Switch!

guess were going to have to start naming our switch mods and firmware after marvel names as well

Petition to rename TrustZoneHax to Stark and call the Bootrom exploit Parker

We might as well call the first CFW "J.A.R.V.I.S."

New PCB makes sense to kill bootrom exploits, but 8GB RAM is probably devkit-only. Odds are this is sold as the same Switch.

 

[Chizko]

Only for the 8gb i would say it is the new devkit, but who knows if it the new switch for 2019.

Anything forked from TX1 won't be worthy of a "New" Switch upgrade. Nvidia is going to have to release Tegra X2 or something similar first.

mario finally changes hsi name to something more murican...good for him!

The cpu clocked at its original clockspeed would be worth a upgrade. Even the increase of ram, since if devs are using more, the final delivered product would still be somehow worse than the original developed on the better devs unit, so a new model with a slighty more ram could be possible.

Kinda makes you think, it would be funny for all the early adopters of a switch system. Hey, thanks for testing the beta model, glad im still waiting for the better revision and more games

All electronics have a (usually green) silicon board in them, it's what all the electronical doodads including the ports (for charging, headphones etc) and microprocessor (that little black thing with the wires out the side, it does all the "thinking") are attached to. This is called an "integrated circuit", or "system on a chip", SoC for short.

The exploits we've discovered in the hardware and software allow us to execute our own code. Now Nintendo can release patches to faulty software via updates, but there are some issues with the hardware (the physical products the Switch is made out of) that means that there will always be some exploits, no matter how much they patch the software.

Nintendo is releasing a new version of the Switch, identical to the old, except that it comes with a revised SoC that shouldn't have as many hardware flaws that can be exploited. This new hardware isn't compatible with Nintendo Switch's 4.1.0 software so Nintendo also released an update 5.0.0 which is a version of the software that will work on both the original and the new revised SoC Switch. Nintendo Switchs containing the new SoC should have 5.0.0 out of the box.

Some people have also discovered that the new SoC comes with additional RAM only accessible to official developers who are provided with developer firmware versions not released to the public.

Essentially what has happened is that Nintendo has developed a brand new console that is more powerful (8GB of RAM allows for more processing power in larger games) and is more integrated with Nvidia's chipset allowing them to access games and other capabilities that the Nvidia Tegra has to offer. Such as a GameCube emulator seen in the Nvidia Shield in China. Look it up. Interesting stuff.
