I have had no luck in getting my PC to talk to drive.
My rs232-ttl I don't think outputs 5v so I have connected the 5v+ from PC floppy drive lead. Not sure what to do with GND. I have tried both GND from serial-ttl and GND from PC floppy power.
The error message on the firmware flashing software says about resetting the device. There is a RESET header on PCB but I don't know what I connect it to for enabling resting.
Sometimes programme hangs for say 20sec before error message, other times message was coming up quickly, so it suggests it is talking with some combination of my leads!
