[SOLVED]Mass storage is not working.

[salva_es]

Hi all,
I am a happy owner of the preenfm2 since December 2019 (vandaal kit) and I built it following the steps in the published guide. The device works fine but I haven't had much time lately to test it. I have seen that there is a new firmware 2.12 (I have 2.10) and I have tried to update it but my preenfm2 is not detected as a mass storage device in Windows 10. I have enabled USB MIDI: IN / OUT in the preenfm2 and access the bootloader and I press "Eng: USB access" -> Access USB Stick nothing happens in the operating system and the mass storage does not appear. If I connect the preenfm2 normally, the operating system detects it as PreenFM mk2.

I have read other threads related to USB problems but have not found a case similar to mine. I don't know what I could check to see if it's a hardware or software problem.

Could someone give me a hand ?

Thanks for any help!

Hi,

Have you tried several times "Eng: USB access" should be enough.
Sometimes it takes a little time to show up on your computer.
Have you tried on an other computer ?

If it realy does not work, you can still take out the usb stick and put it directly in your computer.

Thanks for answering,
I have tried several times "Eng: USB access" on pc and mac without success. The usb provided by vaandal reads perfectly on both systems but is not detected as mass storage when inserted into the preenfm2. I am testing other storage units and will comment on the results. In addition I have ordered another Sandisk Cruzer Blade usb drive like the one seen in the build of the device.

Regards.

Hello,
I have tested the sandisk cruzer usb drive and it works fine. So the problem was the usb drive. I have also tried other generic units without success.

For my part the problem is solved.

Thanks for the update.
Can you share the exact reference of the USB drive you bought ?

[salva_es]

Yes, of course. Thanks to you for designing preenFM2.
