I was going through my stack of Gotek emulators, and I realized that one of them I hadn't flashed with FlashFloppy (I have the flashed ones labeled as such). It's a weird one, with only a 2-digit display (all of my others are either 3-digit or have been modded with OLED).

I remembered why I hadn't flashed it when I got it first. It is not recognized in DFU mode (USB device not recognized, even with drivers installed, removed, reinstalled etc). This is one of the older models, purchased 3-4 years ago i.e. not one with the newer Artery MCUs but rather a STM32F105.

So I took it with me at work today, so I try and flash it in serial mode in a few spare minutes. Flashing apparently succeeded without errors:

1sudo stm32flash -vw FF_Gotek-v4.4a.hex /dev/ttyUSB0
2stm32flash 0.5

(this was of course after first unprotecting the flash with "sudo stm32flash -k /dev/ttyUSB0")

I can't verify if it actually worked until I get home later today. But the display behaves differently from all of the other Goteks I've ever had:

1. Before flashing, when plugged into power but not jumpered for flash: display blank
2. Jumpered for flash, powered on but not flashed yet: displays "8.8." i.e. all LED segments are lit
3. After flashing, jumpers removed and powered on again: LED display flashes for a split second then goes blank. I was expecting it to at least show a F-, but it doesn't.

So I don't know what to think of it. Was this flashed correctly or not? I guess I'll find out tonight.
