USBD_Msc windows10 driver ?

[RixtronixLAB]

Hi,

We tried copying file from nRF52840 board sdcard to windows10,

do you have a driver for windows10 that can be used with USBD_Msc ?

Kind regards,

Hi 

Which sample are you running on the nRF52840 side? Do you have logging enabled, to see if something fails during boot?

The error could be caused by a problem with the SD card, but it could also be a connection issue with the nRF52840, or something else entirely. 

More information would definitely be helpful. 

Best regards

main()

Check that the data lines are connected properly.

That is the error code when D+ or D- gets to the "device detected" state but no actuall communication happens at all - usually because some of the basics don't work.

Thanks for the reply Turbo J,

Is it related with impedance matching, we don't do that,

Schematic and track :

Any how fixing it ?

Hi 

Could you provide the full schematic and layout files? 

Then we can do a proper review, and see if the design looks OK. 

If you don't want to provide your design files in a public case then just let me know, and I can make the case private. Alternatively you can also open a new private ticket. 

Best regards

Hi Ovrebekk,

Thanks for the reply,

For full schematic and layout files, we prefer to be in private case.

We will open a private new private ticket.

It's for USB 2.0, so we don't think impedance match is needed.

Best regards,

Sounds like a plan. I will close this ticket then.
