Segger and Jlink disk

[DPJONES]

Hi

I am using the PCA10056 (nRF52840DK) when I plug in the USB please see below.

It creates a new disk drive Jlink and proceeds to slow down my computer by a factor 20? When I eject the disk the speed of the computer is normal. Can someone please assist.

Regards

David

Hello David!

That sounds odd. Does your computer react in the same way with normal USB sticks or hard drives?

Hi Elfving

No this is the only device the problem occurs, it would appear to be a driver issue.

What is your JLink and nrfjprog version now? And is that Windows 10 that you are running on? Are you able to flash anything to the DK?

Hello again,

Once again, this is odd. Did you try it on another computer?

What you can do if you don't need the MSD option (considering that the terminal works well for you), is to disable it completely. To do this, use the program "J-Link Commander", which is part of the Segger J-Link Software and Documentation Pack, and use the command "MSDDisable" (without the quotes). To reenable MSD, use the command "MSDEnable".
