USB MSD on K20

derekdrost — Fri, 13 Jun 2014 17:44:22 GMT

Hello everyone,

I am working on setting up a USB MSD on an MK20DX256VMD10.

I am using the default example in mqx. (MQX_ROOT>usb>device>examples>msd>disk>cw10).

When connected to a PC, it connects, but it comes up as an unknown device.

Any thoughts on what could cause this?

Thank you,

Derek

Hi,

Please double check that you are not confused the MCU USB port cable and the BDM USB cable, MCU USB port has to be used in this case.

Please connect already running board to USB port of the host.

Are you using a Freescale board?

Have a great day,
Sol

I am using the correct cable. I am not using a freescale board however.

Looking over the schematics, the hardware looks to be set up correctly. Could there be something in my clocks that might be off?
