Hacking Hardware Picofly - a HWFLY switch modchip

[rehius]

ok, I'm going to use the cpu flex v1, because it's erista, my question is, does anyone have a photo of the track where you have to solder the cable that goes to pin 15 of the chip?

any of the two middle traces on the flat connector

 

[detilmalala]

Is it correct that there is continuity between the tracks and the component that are inside the circle?

Here's another quick little edit I did of the picofly logo we've been messing with.

How to add this? And can you add your own one?

I've got a bunch of images in thw aio thread as I'm trying to condense all the useful information to there instead of going through hundreds of temp pages

if you find the rp2040 chip with the flat send me the link, it's gone on aliexpress

I placed the chip, all soldered, I turned on the switch and it turned on normally, no light on the chip, as if I had no chip placed

3.3v / GND is wrong

also might be an outdated firmware

The toolbox0.2 "back to Hekate" option is actually reboot instead of actually reload hekate bin.
I set auto-boot on and when select "back to Hekate" option, I see device boot into my emuNAND.
Not sure if this issue came along from INSTINCT -nx or just translation typo

this is a direct execution of hekate payload. the rest depends on hekate settings INI file.

2.64 glitching faster than 2.5 on my rp2040zero, thanks for the hard work!

Tomorrow I'm soldering back that USB port to try the 2.64 on SKHynix OLED

Yes that’s the same trace

I just usr my spare type-c breakout board and jump 5wires onto rp2040. Feel easier this way. LOL

Thank you for sharing

How to add this? And can you add your own one?

There are realistically two places this can be added: as the background for Hekate, or as a custom boot logo that appears when launching CFW or OFW from the launch menu of Hekate.

Here is a guide to setting the background



and here is a short little guide to setting up individual boot logos for each launch option in Hekate

I changed the chip and now the console works, but it says that the emmc runs in slow mode, what does it mean and how to fix it?

It means you either got a broken emmc or it's corrupt. Either way, it's not good. Double check so it aint shorting.

This is likely related to the resistors that are soldered to the picofly.

47 Ohms is the base recommended setup, but you can put 94 Ohms (or two 47 ohm resistors in series) on DAT0 and CMD lines but leave 47 Ohms on the CLK line.

This is what ended up fixing my slow emmc mode. I also swapped from 47O (that's forty seven Oh, not four seven zero) to 47RO because the RO variants have a tighter variance of resistance (+/- 1% instead of +/- 5% of the resistor value)

what type emmc you have, toshiba?

I have a samsung on a patched V1
