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

Thanks for reply, Torbjorn,

we're running usbd msc

E:\nRF5_SDK_17.0.2_d674dde\examples\peripheral\usbd_msc\main.c

the sdcard can be read on UART but can not be recognized by windows10,

Any clues ?

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,

Any how fixing it ?
