I had same issue, that me get almost crazy, but resolution is pretty quite simple :) Only what you need is change oscilator circuit from this:  , to this:...

I also try floppy_capture_track_test, and last version on GIT, but without luck. Wirings is also OK, and without shortages. 

Its seems, as RP2040 have insufficient voltage to trigger head stepper motor controller to work.

Addendum: I tryied three different FDD, and state is same.

Addendum, adddendum: If i use 0.1.0 (floppy_capture_track_test), floppy it seems work: 

Hello ca0abinary, thanks for help! Now head is moving, and trying to read/write, but without success (GW):     In Flux:   Thanks.

Hi @ca0abinary. For serial debug, you can use CH340 USB to TTL UART (for. example: https://www.laskakit.cz/prevodnik-usb-ttl-uart--ch340), and connect it RX on USB TTL to GPIO 0 (and GND to GND...

I have breakthrough :D !!! If i add 6,8k resistor between IDC 30pin (RDATA / READ), and GPIO12 on RP2040, GW is working OK.   Also when write it...

But now i have problem with Flux, its still not working :( 

With new code, is state same as begin of this issue (doesnt start read).
