Problem starting PreenFM2
Xavier:
I saw this for 2 different reasons :
. Bad display
. bad solder on the power pin
Check the second one.
Where did you buy it ? Mouser change without any problem OLED screen if you email them a picture.

I got the screen from eBay. I will check the power pin.

None of my four new Intensio Nano 4GB stick boot at start up.
Press ENG" at startup works and a screen display and reboot is possible, also flashing...
Choose "MTX: DFU" tells me "STM32F4 USB DFU" and I have to restart. What does it means?
One stick boots sometimes after several restarts!
When I change USB stick when running every USB stick boots immediately! Controller permanent looks for a stick. Is a none working USB stick to fast or to slow??
Older Nano 4GB stick works and "pfm2" folder is on stick.
Is there a specification for USB stick to work properly with an original preen controller?
klangFM:
Found several 2GB sticks. Tested them and they work. Housing is a bit to big, so I removed it.
If some looking for a working Stick, please send me an e-mail.

I do have an issue with the screen display. Between lines two and line three there are lines above the characters. Is this normal or do I possibly have a bad screen/ connection with the screen?

I'm having the exact issue you describe, I can get the bootloader running and boot into the bootloader mode, but I cannot boot normally, I just get the full blocks in the OLED. I have a self-made preen405.
I removed the preen405 and put it back in, but it did not help. Did you say that you soldered in place in stead of using the socket?
