Cannot run a precompiled example hex file

[junma]

Hi all,
I have one PCA10040 board, and want to start to download and run some examples while reading the on-line documentations.
In section "Running precompiled examples ", I see the description of copy and drag an existing hex file to the standard USB drive. I've tried several times to copy and drag hex files to the USB drive, however, each time after I dragged to the drive, seems the USB drive will reset and delete my dragged hex files. Attached is the capture of the USB drive.

Is there any procedures that I missed? Hope someone can help me about this issue. Thank you in advance!

Best regards.

the drive doesn't delete the file, it uploads it to the chip for you, after it's uploaded you will no-longer see it on the drive. The drive is just for transport.

Hi RK,
Thank you for your reply! But the problem was that I didn't see the effect out from the board, even I pressed the "Reset" button or power-off then power-on the board.
So I thought that the hex file was not flashed to the chip.
