evening
my gotek with the oled idsplay only shows random garbage when powered up making seeing what slot number problematic to say the least.
images load ok though . if i turn the cable round i get a clear message telling me that .
ive swapped usb sticks clean installs etc but always get same result.
wiring is correct.
i know i'm prob doing something daft but after reading everything i can find i'm still puzzled.
the drives came with the oled fitted .
cheers phil

When this happens the OLED display needs resetting, do this: try leaving the ground on back of the actual PCB drive, then touch 5v on (so leave all the OLED connectors plugged in, and try the drive itself to see if that resets it).

I had this problem and it fixed it.

do you mean the jumpers near the power connector ?

I had a gotek OLED which had garbage on it and this was due to using a USB 3 stick. Went back to USB 2 devices and have avoided using USB 3 devices since with my goteks.

Flashfloppy firmware? If so, have you changed USB sticks lately, therefore using a different FF.cfg that has a different sized OLED in it (128x64 vs 128x32) specified in it? That can do it, for sure.

I had a faulty OLED which came with the GOEX drive. When powered up with the drive (or a GOTEK) it would display garbage but quickly disconnecting and reconnecting it would fix it, until the next power cycle. I just replaced the display with one which worked.

Cheers gents will try those suggestions after work

Thanks for the help all working .

Out of curiosity, could you post a detail picture of MPU (main chip) markings?
As there is a shortage of STmicro MPUs, Goteks with different chips surfaced lately. And I mean completely different architecture chips, not just fake STM. Such are of course not compatible with FF firmware.
