Gotek and FlashFloppy E34 error

Post by Mooger5 » Sat Jun 30, 2018 10:54 pm

OK, so I bought a Gotek SFR1M44-U100K USB floppy emulator for the SY77.
It should have been the 720k version, I know, but that was the only model available at the local importer. Seeing that you need to adapt the 26 pins to 34, just like with the 1.44 floppy drives that reportedly work with the SY, I thought I´d give it a shot.

I didn´t use an adapter BTW, having instead desoldered the 34 pin and the power connector and soldering directly the 26 pin cable from the SY to the Gotek´s PCB. I believe I got the connections right, but if someone knows of any shortcomings, please advice.
I also tried different jumper combinations, several thumbdrives, several formats. Nothing worked. Even pressing both buttons at startup for the auto-format feature. It did autoformat the thumbdrive, but the SY kept saying "bad disk".

On the FlashFloppy site it´s said the only difference between the 1.44 model and the 720k Gotek models is in the firmware, and that the FlashFloppy firmware is the same for both models, so I flashed it in according to these instructions:



It´s apparently working as it should, as it even lets me update the firmware via USB thumbdrive only.
But the error E34 keeps appearing :(

Any thoughts?

https://github.com/keirf/FlashFloppy/wi ... r-Messages

So E34 means "No entries to navigate: Direct Navigation mode found no valid directories or image files to display. Add some valid image files to the USB drive."

I´m also missing the initial setup.

" Initial setup has two basic steps:

Set up the physical interface to the host system
Configure the operating mode for image navigation
Physical Interface
By default FlashFloppy will emulate the Shugart floppy interface. This is compatible with a broad range of systems including Amiga, Atari ST, Amstrad CPC, and many other devices. Shugart-compatible systems will typically expect the Gotek to respond as 'unit 0'. Therefore place the selection jumper at location S0 at the rear of the Gotek.

IBM PC compatibles use a slightly modified interface which places the disk-changed signal on a different pin. To select this interface mode place a jumper at location JC at the rear of the Gotek. The host system may expect the Gotek to respond as 'unit 1': in this case place the selection jumper at location S1 at the rear of the Gotek.

An alternative method to specify the interface mode (Shugart or PC) is via the FF.CFG file.

See Host Platforms for detailed instructions and troubleshooting for specific host systems."

So I must place the jumpers at the JC and S1 and configure the OS for PC compatible. The odd part is there seemed to be some consensus the jumpers for the SY77 must be on S0=M0. Anyway, I´ve got a lot to do.

I really could use some help here, folks.

For instance, I can´t find the FF.CFG file. Everytime I put the thumbdrive back in the computer, it comes with a file named IMAGE_A.CFG. Is this the same as the FF.CFG? I take it FF is for FlashFloppy. But that´s about it.
The only time I get 000, 001, 002 etc is when I write some files with the .HFE extension, but the SY77 returns with a Bad Disk message. It would help if the files were in true SY format, but I can´t find any on the net. Is there a way to convert a .syx into a .J01 etc?

I´m going to recheck the connections, maybe I´ve misplaced a wire or two. The Gotek doesn´t need to be linked to a host for the firmware and to be installed, afterall. Just because the new OS is working OK is therefore no guarantee that the Gotek is correctly wired to the SY77. In fact, that may just be the cause of the Bad Disk messages.Fingers crossed.

Found some mismatches. This is the way to connect a 26-pin to a 34 according to the FlashFloppy Wiki.

(26-pin) -> (34-pin + power)
1 -> 5V
2 -> 8
4 -> 10
6 -> 2
7 -> 12
8 -> 34
10 -> 16
12 -> 18
14 -> 20
15 -> GND
16 -> 22
18 -> 24
20 -> 26
22 -> 28
24 -> 30
26 -> 32

It WORKS! :mrgreen:

Had to copy the FF.CFG example to the thumbdrive and edit it to 'interface = ibmpc' and put the jumpers on S0 MO for the wire connections posted above.

I saved ALL to the Gotek, then did a factory reset to the SY77 so the Internal bank would be identical to Preset 1, then loaded the file from the Gotek again and it went back to the Internal bankprior to the factory reset.

It works, and it works nicely.

Thanks for your attention.

I know I'm coming to this very late, but I've just started playing around with a gotek for Amiga and received the F-F error. Worth noting - I was frequently Amiga Amiga CTRL, and no problem when I was switching off from power. I wonder if the Amiga reset has and affect.

"F-F" isn't exactly an error. It usually means there's no USB drive connected. Double-check that the USB drive works by reading it in a computer. Make sure it's a FAT formatted volume.

It's not unheard of for USB drives to go dead when used with a Gotek installed in older equipment with bad (poorly regulated) power supplies. The dirty power can kill them even though the Gotek survives and the device (Amiga, in this case) is still working.

:roll: I got a GOTEK for my EPS16+. Was told it had been flashed for Amiga. Anyway I followed the instructions, did the FlashFloppy and DfuSe, dfu upload, all that seemed to work ok. Removed the 2 links, put a jumper on S0 connected up into EPS16+ power up.
First got the F-F message and then E34. Ok so the F-F is the FlashFloppy firmware got upload ok, and the E34 means, put some files on the USB stick dummy. :lol:

So I put the FF.CFG for the EPS16+ and the img (800k) for the OS1.3, and... still get the E34 message. I try a different USB stick, same E34. I had tried the hfe (1961k) versions, still the E34 message.

Both USB mem sticks read ok on my XP32 computer.

Any clues?

If you have the normal 3-digit number display on the Gotek rather than the OLED upgrade then the disk images have to follow a particular naming scheme: DSKA0000.HFE for the first image, and sequentially thereafter.

If you have it configured perfectly then you can also use IMG files instead. On a similar note, EPS/EPS16 will have issues with disk change detection unless it's configured very specifically.

Thanks Mr R, that got me sorted.

It all seems a little bewildering now though, so I put my *.ede files thru EDE2IMG to get *.img (800k) omniflop image, which is ok. And then I have to rename the file to DSKA0000.img - I then loose track of what files that image contains say: OS1.3, piano-a, bass-b

Has anyone got a program that can print out the contents of the *.img??

I have EDM and that can print out physical disk contents to make a floppy label, nice, but no use here. It can also list the files contained within an ede file, so I'm almost there, but I can't find a way to save the dos screen output to a text file, so then I can compile a text listing of the many DSKA0000.img files.
Best I can do is jpg screen captures, better than nothing I guess.

I think this will achieve what you want:
https://mega.nz/file/BRFB0ADK#3VqFrz8bV ... oISaYkkWVk

It will spit out text files of all your mystery DSKA**** IMGs, HFEs and such. Or dump them all to EFE, if you want to load them into Kontakt or whatever.

Should work on XP or newer. Reports are just text files which can be opened by Notepad.

Thanks Mr R that works perfectly on my 32bit XP, makes the GOTEK solution simply the best. It's so easy to transfer my ede now to the sampler via this GOTEK device and also to have a library listing of disk contents.
