Would be nice to make a video of the issue. The description is confusing.

There is something to test into your email box.

A video of what ? The bugs I found ? Well, it doesn't need a video.

The facts : I've 4 disk images on the USB stick.

Now, if I press the up button for a long time and not release it, here is what's happenning on the digits :
000, 001, 002, 003, 000, 001, 002, 003, 000, 001, 000 then the sequence stops (3-times cycling)

Now if I press the down button for a long time and not release it, here is what's happenning on the digits :
003, 002, 001, 000 then the sequence stops (no cycling)

For the debouncing problem, you can see something like that on the digits everytime you press the button (up or down) once :
- up 000, (001), 002 or 001, (002), 003, there are glitches.
- down 003, (002), 001 or 002, (001), 000, there are glitches.

That's all :)

What about the most important problem I have with my Gotek ? Did you find something wrong in the signals chronology or state changes that not occurred in the disk changed protocol ?

Great, I'll test that in the late afternoon and I'll keep you inform.
Many thanks :)

I've just updated the Gotek drive with the firmware you sent to me. Well, it's worse than before. The synth doesn't refresh the files. I can't see any filenames on the synth. So, impossible to load anything :(

I use IBM PC 1.44MB mode. I also tried some other possibilities but no success for the moment.
No luck.

I see that the synth fdc is NEC uPD72070GF, datasheet is here http://www.datasheetarchive.com/dl/Scan ... 101535.pdf

Try this : force the drive selection (the jumper) to the ground and retry.

Do you mean the DS1 jumper ? If so, it's already connected to ground.

Not sure you understand me : Have you already permanently forced the drive selection with a wire between the vss/gnd and the selection signal (DS1, wire 12) ?

Yeap !!! I did it and great news ! It's better ! It works but there are still some troubles with the green LED that always stays lit. Also, I need to touch the screen of the synth twice to make the refresh happens. But now, I can change the disk images and the synth can refresh when I change the image number. Great improvement ! Thanx Jeff, U R the best !

Tested :
Loading -> OK
Writing -> OK
Deleting -> OK
Formatting -> Fail !!!

Just another thing, normally when I insert a floppy and change it to another one, the synth always indicates "Medium changed" and I must press "OK". Now, I don't see that anymore.

What I did is to remove the jumper (DS1) on the Gotek and connect a wire between GND and pin 12 of the Gotek connector.

To go further, I've tried something that made the synth react as it should do. I mean, it can now display the message "Medium changed".

What I did is to make a positive pulse on pin 12 :

1 - Select the image to load
2 - Remove the wire on pin 12 (high)
3 - Put it back again on pin 12 (low)
4 - Refresh the files by touching the screen

And that's all !!

Now, how to make that automatically ?

Which interface mode are you using ?
Can you try this : remove the usb stick, wait some second (4/5s) and reinsert it. is there a media change message ?

Btw can you try the previous version firmware (the current one available for everyone) ? It should work the same.

I tried IBM PC 1.44MB then switched to auto and it was working the same (Shugart was working too). I'll try others this afternoon and original firmware too. I'll tell you :)
But, forcing the drive selection to 0 is not correct functionnaly speaking. :(

Try the usb stick ejection trick before.

It works, well. No refresh problem :)
Now I'm trying with the original firmware...and, same behaviour as the modified firmware you sent to me.

Changing the mode doesn't change anything, everything runs the same way.

I retry to format. The fact is that it works, but it's very very very very long ! Saving too ! It's really slower than a real floppy. Oops !
Deleting and loading are quite normal.

Hi,

@jeff, have a look here about how to detect a disk changed, maybe it helps :)
