Hacking Hardware Picofly - a HWFLY switch modchip

[billybobxxx]

looks fine, BUT ensure your rp2040-zero is fully connected and working (blue light).

I had such smoke several times when forgot to solder the GND wire

We can remove this caps and the switch will still works without any problem?

 

[SkylerTakashi]

yeah but they all connected to each other so bridging shouldnt be an issue.

So all the wires can overlap and touch one another with no issues?

 

[Tom8823]

Just an idea.

Is there a way to reprogram Pico to allow pins 13-9 (selected in green on picture) to act as a USB lines?

So for instance when we desolder USB port and we want to re-program Pico with software update it would be easier to solder pins to big pads on Pico instead of smaller pads to add ribbon cable

Wires cannot touch. I was referring to the double points.

Oh got it

Even better, thanks.

I just got the mosfets from digikey, theyre about $.50 a piece
Ordered resistors too but they ended up being 47K and not 47ohm which is what prompted me to salvage them. Other than looking at what boards you have or checking schematics if available, I think it might just be easier to order them. Especially since the ones that are recommended are specific models and not just any old mosfet.

That's what I was leaning towards, but your post just gave me hope and got me thinking about it again. I'M BROKE!

If I order anything, I think I'd rather get some flex cables (gonna use my SX Core flexes to test installing the coming Picos on a V1 and V2, after that HWFly flexes?) and OLED adapters.

Yeah it works fine.

Yeah it works fine.

But picofly work?

Just to confirm this is the route I went down.

Just to confirm it boots 1 in every 20 odd times on the switch lite so I have left those both aside. Now v2 have it working instantly every single time but I get the hekate failed to open payload.bin

What is the correct sd card setup for this as I have tried everything including using a sd card backup from my working V1 trinket build and fresh setup of hekate and atmosphere. Also if anyone sees this message and is struggling, V2 wire sizes don’t matter iv tried multiple and all get the same result, I have found that soldering directly to the cap is the best option though.

See attached image of correct method for V2 tested working.

Have hekate or your atmosphere bins named as payload.bin on the root of the card, obv copy any other files they mightve came with in the zip

you have to download the last hekate.bin file and rename it payload.bin and copy the payload.bin on the root of your sd card

Hello.. I have a V2 that installed a HWfly into was working, but I get bored and installed the Picofly using the same V2 CPU Ribbon.. I'm getting a Blue then White or teal hard to see.. but console boots straight to OFW.. I installed RST to Motherboard and the others to the emmc.. point was just alittle safer.. thx for any help..

edit: I flashed to 2.5+unlock file

Yeah I did that and it wasn’t this. The issue was the sd card reader wasnt plugged in correctly lol

This looks like a V1 to me, not V2.

First cap is vertical not horizontal

 

[AngryHelder]

Hi,
Is there a need for two parallel np2016 mosfets (Like there are on hwfly flex for v2 mobos) instead of one IR... Mosfet for mariko?
Or one np2016 will be enough?

Thnx 4 reply.

I'd like to know this too

Can that pad be used for dat0 on v2?

Mine

My image looks like it’s soldered there but it isn’t. I have come off the boards connector for Emmc pins so I can remove and upgrade the Emmc size later. This was just a test run to see what’s the best route to take when doing this with wire size, locations and placement etc. I’m in bed now but can go over with multimeter later and find more alternative pads.
