Oled screens not working

c957655337c4cf59

I’ve installed everything and STM32F4 app is running. Everything is working but the OLED screens do not.
I doublechecked everything and it seems to be ok.
Is there some kind of configuration that i missed out? Is there a way to test the screens?

And the correct HW.V4 file is on the root of the SD

Hello,

Typical causes are:

Core J15_S jumper missing or wrong voltage (should be 3v3)
Core R33D wrong (should be 560R)
Poor cabling
Poor contacts of IDC female plugs into headers
Bare end of IDC cables touch each other or the OLED PCB
Insufficient USB power capacity

Best regards,
Andy

Hello dijf. I hope you managed to get them working. What was the issue? Cause I’m facing the same problem.
@ latigid on: may be I missed out some parts more than the ones not needed for these displays?
