Problem starting PreenFM2
« on: January 08, 2018, 05:38:48 PM »
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.

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

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.

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 ?

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.
