Problem starting PreenFM2

[memorysplice]

Hi  I am having issues booting from USB stick.  It will load into bootloader, but will not load into the synth.  I have tried to reformat the drive I have tried to use a different usb stick.  I have tried to reflash the bootloader.  I have checked the connections on the usb port.  I do not know what to do next.

what happens when you are in bootloader mode and access the usb stick via pc/mac? is the stick recognized by the pc/mac? can you move/delete/create files/folders?

what do you see on normal startup on the display? where does it freeze?

I can not see it in Mac or Windows.  It shows the block on all of the OLED when I start the synth.  Tried the instructions in the FAQ and no solution.

[lokki]

ok. the usb-stick directly on the pc works? how did you format it? /pfm2/ directory created? (just pointing out the obvious)

I have tried to format in both windows and osx using the basic format tools to format to fat32

That make me thing you didn't put files in a /pfm2/ directory, did  you ?

Haha just went to the other thread and it seems that was the same problem.. Thanks Lokki

It is in the pfm2 folder as instructed.

By the way to see it on mac or window you have to enter bootloader mode.

If you see only blocks on your display, it's not in bootloader mode.
So either you didn't press anykey when  you swtiched your preenfm on, or your key press are not detected.

I can press the top button on the left and enter bootloader mode but it will not access the usb drive.

OK perfect, there were recently people who soldered SMD components on preenf405 PCB themself. Are you one of those ?
Or is it a preenf405 you bought from me ?

[memorysplice]

I am the guy who requested for more stuff from you on Facebook. :-)

[Xavier]

Ah OK so you have a real preenF405 
The preenfm405 to usb stick connection is direct, so there should not be any problem.
And i test them all before shipping.

What USB stick did you test with ?
You said I would suggest to try with a third one.

[Xavier]

... and if the one i shipped does not work. I'll ship you a working one.

[memorysplice]

I will try with a third one.  Is there a possible issue with formatting in fat32 in Windows 10 that might cause the issue?
