FIlename format - unclear

Solved myself but didn't see a post with the solution.
Make sure and reset the EEPROM config (no flash drive installed, press and hold both buttons for 5 seconds, display changes to 'rst', release the buttons.

Background:

• Roland MC-50 with GoTek
• GoTek Floppy Emulator with the 415 chip and 3 qty 7-Segment Display (no mods)
• Flash Floppy Firmware 3.43 successfully flashed.
• Read almost every wiki page and found mentions but not together with clear examples.
• Additional Reference: https://thiscow.fr/2020/11/27/roland-mc-50-gotek-floppy-emulator/
• Additional Reference: https://gearspace.com/board/showpost.php?p=13585675&postcount=57 Also downloaded image file from here.
• 4 GB USB Flash Drive formatted Fat32
• FF\FF.CFG contains

• nav-mode = indexed
  

• indexed-prefix = "RolandMC50_"
  

• FF\IMG.CFG contains https://github.com/keirf/flashfloppy/blob/master/examples/Host/Roland/IMG.CFG

• [mc::737280]
  

• + other related key/value pairs from the Additional Reference sites.
  

• Root of Flash Drive contains (root only because: indexed + 7-segment)

• RolandMC50_000.mc.img @ 737,280 bytes
  

• RolandMC50_001.mc.img @ 737,280 bytes
  

Result:

Error E34
I've tried lots of different variations on this but no luck. Did I misunderstand this feature? Is this not supported? Is this a bug?

Simplest Test:

• No CFG files, no folders, fresh Fat32 Format
• 3 files DSKA000.img, DSKA001.ima, DSKA002.dsk

Result:

Error E34

Does the filename have to have 4 digits? There are only 3 qty 7-Segment, so this seems error prone.

Not sure if it's relevant but when reassembling my equipment I wasn't clear on where the jumpers should be on the GoTek so I moved them all so they didn't connect anything (ex. S0 is OFF). Is S0 required for Flash Floppy? Any idea where I would see the error for this?

[keirf]

Yes, it has to be four digits, like RolandMC50_0000.mc.img, as described in https://github.com/keirf/flashfloppy/wiki/Image-Navigation-Modes#indexed-mode

[keirf]

And yes you need a jumper at S0. With no jumper at all, no drive-select wire is connected, and the Gotek will never be selected, and so will never respond to any host commands.

Thank you, I restored the jumper and renamed my files to include 4 digit numbers.
I found a reproducible issue with this feature and reported Issue #971
