Hacking Hardware Picofly - a HWFLY switch modchip

Does this firmware require an RP2040 board with a larger capacity Flash?

Post automatically merged: Mar 24, 2023

The default flash for RPI PICO is only 2MB in size

RP2040-zero uses same winbond W25Q16JVUXIQ flash as rpi pico i believe

你能在RP2040板???中指出这一点吗？

The premise of this is that the RP2040 has a 3.3V supply inside the NS.

Type C pins are 0.254mm wide approx, not sure you get pogos that small tbh

Maybe it's for sale on AliExpress? I can buy it locally

it looks really thin, you could probably find/make space in the oled somewhere

normal rp2040 does not fit?

don't have an oled, but i believe the pico-zero board could fit in too, but only if the buttons and usb c port are removed

Why is the firmware and unlock firmware in PDF extension? It needs to renamed to .bin right?

to .uf2

 

[susi91]

this works for everyone

Probably a very dumb question (never messed with this tbh), but how fits the 4MB bin file into a 2MB Pico-Zero flash storage?

forum software only allows uploads of certain file extensions. As noted, rename to .uf2

Broken how? as long as you have at least the D+, D-, 5V, & GND lines on the board you can wire to it.

Sadly it seems to be software locked. I guess zip files work still?

Longshot but would 47k resistors work? Turns out Digikey didn't filter my resistance option well and 47k got into the mix of results and it was the cheapest......
