I have seen this sometime back. However i think it was tested on 16MB nands and not on phat xboxes at that time.

But no mention of phat xboxes in this post as well. It certainly looks promising compared matrix nand flasher 6m, jr programmers 3m30s. I have only these 2. So...lets see

It's slow, I believe I saw someone state it takes roughly 10 minutes to dump a trinity nand. However it will be more accessible to some people than a regular flasher which is a win.

Yes that is what i also read. But OP states 50seconds approx. This is a different developer, so this is good stuff if it is stable and if it works on phat. Dont have a phat or a pi pico to test this. ?

So I haven't quite got this working yet, but I am in a discord with the developer and he's shown me videos proving that this new method actually beats out the xFlasher in terms of speeds. It operates at a higher MHz then the xFlasher allowing it to be faster. He is currently working on J-Runner support, so hopefully soon this becomes a standard.

Thx for the update!

Tested on jasper 16MB, took 1 minute 17 second to read nand, write longer almost 2 minutes.

Thats faster than jr programmer but the important thing is pico is cheap and widely available. Wonderful ?

Any photos or wiring diagram?

Thanks, was this the same wiring you tried but didnt work? I will order a pico just for trying.
Oh I haven't gotten it to work because Im unfamiliar with linux lol not because of the pico trying to learn my way through it

Hi, do you tested Raspberry Pi Pico to read/write xBox 360 Nand under Windows OS or Linux?
Does "J-Runner with Extras" already support it?

J-Runner doesn't support it yet, the developer is working on adding support though

Both, windows 10 & ArchLinux

pico run at 125Mhz default compared 32Mhz Nand-X, 20Mhz JR-P, 12Mhz MTX. Actually that considered slow (expecting below 1 minute) for that speed freq, maybe because I used 100R resistor for safety on all pins.

maybe I'll post later, still don't know how to put pics on post, LOL.

Just got it working with an experimental JRunner version, it dumped my 16mb jasper very quickly, I didn't test writes but it read it in under a minute.

Edit: I also made this pinout for Trinity motherboards to help make it easier to see where wires go

Does this Trinity scheme work with Corona?
The points aren't the exact same iirc, it should work for 16mb coronas just look up the nand header points and match the colors basically, ill make another diagram later tonight

I just received my pico. Does anyone have the compiled version (.uf2) and instructions for using it in windows?
