Hacking Hardware Picofly C Point fail 1.663v

[McLaren670]

I've had the problem for a few days now that the picofly doesn't start. According to the LED, the D0 soldering point is what I measured earlier. I have a value of 1.663v at point C. Where is the error? Can you help me? I don't feel like opening the switch anymore

There are two threads about the picofly you will get better answer if you ask on that threads, you can use the search bar at top of page.

this is not a picofly chip, it's an rp2040-based hwfly. you won't get any support in the picofly threads.

Picofly is the nick name to raspeberry pico (RP-2040) - Hwfly hybrids on the wild.

the two large threads support the rp2040-zero/rp2040-tiny chips only, not these undocumented things

but to be constructive instead of just complain, the issue could be related to the fact that whoever makes these chips puts way too strong resistors on the dat0/C point connection, over 200 ohms. try switching to a 100 ohm resistor instead

what value do you get when you reverse your prob, red prob to ground, black prob to C point

I also replaced the chip from picofly to hwfly, both have this error, it's the dat0 contact that doesn't have a proper connection, a bit of fiddling then it works, as soon as I shut down the switch completely it no longer works and boots into the OFW

So rework the DAT0 adapter? What do you mean with fiddling exactly? Push the adapter in gently? Did you solder the ground anchors on the shield and the anchor next to the eMMC?
