Solo hice estas capturas de pantalla jeje, ya salí de mi laboratorio jeje tengo que madrugar, mañana subiré más imágenes, muchas gracias a todos por su ayuda.

Wrong 3.3V point

I will review this point again when I have the opportunity, thanks

hey guys, to grind and reveal this part here on oled do we need to use mini grinder? or its possible scrape it just only using scalpel ?

I always use a scalpel

OLED RP2040 install, First time i have had an issue but also the first oled install. I have done dual mosfet. When battery is plugged in i get blue LED then goes off. And then when i then click power button no LED shows and OFW boots. I have permanent DAT0 installed soldered under emmc. what have a missed?

edit:

I have the same problem, I have 2 mosfets connected and when I connect the battery only the peak turns on and the light turns off. What is the solution to this problem in Oled models?

Hey man. So just installed a oled HWFLY cpu flex and same result. My wiring is 100% legit so it’s either something with the rp2040 OR the oled doesn’t like the small enamelled wire, I am just going to flash another Pico and report back.

I just solved this problem, I just changed the 3.3v cable to its correct place and now everything works perfectly. Thanks to everyone for the tips. the error was mine in this installation.

Also just solved mine. New Pico worked fine. Flashed the old one again and no luck. Not sure what that’s about. They are brand new lol

@Mgt and @SeriousC where are you getting the wrong diagrams from? Surely it's not from the AIO guide.

I didn’t have a wrong diagram mine was faulty Pico. Swapped Pico to a new one and instantly worked.

Now i know why my order still waitng to ship from china ...

Just got an update from seller of RP2040Tiny "thanks for your order, but sorry to tell you that RP2040-Tiny-Kit has small quality problem, factory has recalled the products and reproduce. it need about another 1 month."
And now my wait begins...

Hey guys

EDIT: Could update it through payload picofly_toolkit. Now im facing the next issue FML.


When i go to console Info on Hekate it says eMMC is runing on lower mode but is still 400Mb. When i go out and revisit the console info it drops to 200 mb. The OFW seems also not starting. CFW is working. Any idea what the issue could be?

Maybe the wires are kinda long on a part somehow?

From the guide: "might be caused by not cleaned flux, bad soldering, lack of resistors, too long wires or too thin wires"
Had the same situation 3 days ago (on V1 unpatched switch). One additional 47R resistor on dat0 line solved the problem.
Maybe it was the wire (38awg single core) but I was too lazy to swap the wire so I tried the resistor first and it worked.

Where are you guys placing the 2040?
I've got mine on top of the memory ICs, but it's a tight fit, even with the PCB cut down Plus, with the height of a standard waveshare board, it looks like it's going to hit the shield/heatsink anyway.

Have a weird one and its already at my customer... He send me this video above.
May be You guys have experience with this issue?
He told me its boots fine at the first time into atmosphere but when he just installed some games the console just reboots into ofw. Then its no longer boots up into bootloader/atmosphere.
Customer will send it back to me today.

looks like cyan to me
something wrong with mosfets/cpu line

hmm, for me its looks like green but I will check CPU flex! Thanks!

 

[Marsowaty]

Hey, I have a problem on my switch lite.
Picofly not working, i remove pico and flex.
Nintendo start OFW, but have a problem microsd. Try three microsd and nothing.

And second question. Flex mosfet has three resistor that's right?
I have a bridged resistor (multimeter 0.000 and beep).
I marked in the picture, Please help me

 

[dz213]

I used IRF8714 on Mariko.
Another guy used IRFH3707 on Lite.
I also think (didnt try yet) that IRF8736, AON7506, AON7518 should work. Check the parameters on these and try to find something similar if you are in the "experimenting" mood.
Good luck

hi
can you tell me which mosfet will work :
IRF8721
IRF8707
IRF8788
thank you

Yes ir cyna problem with mosfer.Make now over 30 + oled check install

oooo for me some problem :
hello dear, thanks for your order, but sorry to tell you that RP2040-Tiny-Kit has small quality problem, factory has recalled the products and reproduce. it need about another 1 month. Could you please extend the delivery time by another 1 month? if you need the products urgently, please cancel the order. Sorry for any inconvenience caused. regards, Gintech team

From these 3 i would go with IRF8788

I think that mine has been already sent, don't know why...

Probably it was before they read this thread and understood that they fkd up the resistors value after people confirmed it was 470 Ohm, and not 47

 

[Kiuxn]

The resistors are those placed close to the pins and perpendicular?? it seems that he just bridged the connection and then placed bigger sized smd on the pins right?

yes

 

[MAI87]

@Mgt and @SeriousC where are you getting the wrong diagrams from? Surely it's not from the AIO guide.

I was guided by the correct scheme but I was wrong at the point of vcc. my mistake.

 

[jkyoho]

. Flex mosfet has three resistor that's right?
I have a bridged resistor (multimeter 0.000 and beep).

The middle resistor on the flex is indeed 0 ohm, in order to put both MOSFETs Gate together. Nothing wrong
