Hacking Hardware Picofly - a HWFLY switch modchip

[Dee87]

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

Oh okay thought u meant on the rp

Srry can't tell u that don't have the oled open other wise I would check

 

[detilmalala]

could someone make or share a link of some tutorial from chip programming to test run, using mosfet, thanks

Beautiful soldering, I would like to use this method too. Are both wires soldered to the CPU of the rp2040? Can these two lines be merged?

After playing around with the switch for a while today, 2.61 definitely takes longer to glitch than 2.5 or 2.6 did (Patched Erista, rpi2040 pico).

Edit: Resetting the training data using the toolbox seems to have fixed it.. will keep watching.

 

[eseldiem]

That is why it's alpha, once everything is fixed I post a new version.


fixing this right now, software update related thing.

I’ve tried make the OFW work using the following:
- restored known good boot0
- regenerated boot0+boot1 using emmxhaccgen
- restored full backup of 14.X, then upgraded to 16.0.1

Still can’t make the OFW boot from sdloader or from hekate’s restart->OFW.

Can boot it using “launch stock” entry, tho.

As I said, no biggie.

For the record, fw 2.6.1, upgraded via toolbox from 2.6. Console is Mariko (v2), rp is waveshare zero.

If I would use a rpi pico, how could I know what the issue is since it doesn't have a rgb led

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

What about the boot loader? Wouldn’t that need to be updated via USB?

Flashed 2.61 via toolbox

open picofly toolbox

Starting with 2.6 alpha, you can just update the chip using a special payload

how to access "picofly toolbox"? and what the difference if i run hekate > payloads > click update.bin?

What about the boot loader? Wouldn’t that need to be updated via USB?

what is bootloader?
im so sorry, just understanding it one by on. thank you for your time

 

[cliffkhew]

May I use v2.61 update.bin upgrade method with a v2.5 fw Picofly?

No problem man,I found that the resistor is a 3.7k ohm.

4.7k ohm to be cleared

 

[everyonesweird]

do i rename the 2.6.uf2 to .bin to update? or may i have the update.bin file link please.

 

[FANJIAQI]

2.61

- no more magic for xiao/itsy, detection by shorting pins
-- for xiao2040 please short GPIO 1 & 2
-- for itsybitsy please short GPIO 2 & 3

- moved to the latest sdloader version (I know, logo sucks now)

- software update bugfixes, rollback works fine now

i use usb to flash FW 2.61.uf2 ， should i still flash unLock.uf2 ？

 

[Dee87]

do i rename the 2.6.uf2 to .bin to update? or may i have the update.bin file link please.

update.bin is a few pages back or klick on the top of the thread ther is a field with importend post if u click on fw 2.61 u will get the post shown or u go to th AIO Thread and there are links to everything

i use usb to flash FW 2.61.uf2 ， should i still flash unLock.uf2 ？

no

Guys, can someone confirm. If i can use the switch v2 flex cable to switch lite?

yes since its a mariko board u can use V2 cable On v2/Lite/Oled

Guys Does the length of the wires matter?I saw so many comments that need more length for it to work?

Ask any Woman if the length matters

no the shorter the better ther where some board who needed for some emmc i think it was for the toshiba emmc

 

[FlowerFire]

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
View attachment 363672

Is it ok to short those two 3.3v points? (I do get continuity between them, but it never hurts to ask about it )

Also: Is it safe to boot up the Switch without the cpu plate and heatsink back on? Of course I mean just for testing if the install is alright and then turning it off again. I've seen it being done in some videos, but you never know

AWG36 to be exact.
