Hacking Hardware Picofly - a HWFLY switch modchip

[Ganesha0112]

How can I update a pi zero trough toolbox?
The chip don’t have the USB C port

hey guys i found this thread and i didn't follow it at all but i'm really intersted in it, someone has done a guide for doing this ?
or i need to read all of this ?
if there isn't a official guide to follow i'll try to do one by myself and maybe share it with the admins
thx to everyone

Guys did anyone use 0.10 wire for mod and does it work as I think it's to thin?
Can someone confirm that works.

Works on all models.

yes it works for everything except the wires from caps to mosfet if u use wires installing the mosfet

I often replace m92t36 so was thinking of using another 3.3v point so to not run wires around m92 incase it ever needs to be replaced

The emmc board has a 3.3v point that I guess sx core and hwfly clones use with the solderless chips

That’s what I was wondering, too.
And for the same reasons.

yes u can also use it from the emmc i have done it on my v2 so no problem there

Is there a way we could incorporate the data lines from the switch to the picofly, and have a sort of update mode so we can flash the pico with the switch usb-c, that way we don’t need to open the switch and re add the usb-c every new update?

So what do you recommend to connect the caps to the mosfet ?

i would recommend using flex cable
or direkt soldering to the caps
wire for caps to mosfett i would say 0.4 or 0.5 i guess

I used AWG36 except for 3.3v/GND (AWG30). No issues at all.

Starting with 2.6 alpha, you can just update the chip using a special payload, no need to use USB.

MOSFET or flex? If MOSFET with cable or direct to cap?

However u want to do it

Can someone tell me the value of the cmd resistor on the OLED?

 

[Dee87]

Pinout for XIAO2040
@Adran_Marit if u want to add this to

same as the for every other board 47OHM

I used wires to the MOSFET, MOSFET is sitting next to the CPU. See here, before it glued it down: https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/post-10113097

The one on the board side.ot the one on the rp2040 47OHM.
I knocked of the resistor on the board cmd resistor.
