DFU

Doc ID 16617 Rev 1

29/35

After installation, “MEMS demonstration DFU” appears in the DFU USB devices list

(

Figure 18).

To execute the firmware upgrade:

Click on File > Open, select the directory where the “.dfu” file has been downloaded,

and select it (

Figure 19).

Click on “Upgrade”.

The internal Flash memory will be erased (

Figure 20) and reflashed with the new

firmware (

Figure 21).

Once the procedure is complete, a Windows message appears, stating that a USB device is

not recognized. The user can then unplug the USB cable from the STEVAL-MKI0xxV1

demonstration board and use it with the new firmware.

To back up the user’s current firmware before flashing the demonstration kit with a new one,

flag “Upload DFU device” (

Figure 18) before clicking on “Upgrade”. The user is then

prompted to save the current firmware in the preferred directory before the erasing the

internal Flash.

Figure 19.
