The interface MCU features a
Mass Storage Device (MSD). This makes the Preview Development Kit (PDK) appear as an external drive on
your computer.
This drive can be used for drag-and-drop programming. However, files cannot be stored on this
drive. By copying a HEX file to the drive, the interface MCU will program the file to the
device.
Note:
- Windows might try to defragment the MSD part of the interface
MCU. If this happens, the interface MCU will disconnect and be unresponsive. To return to
normal operation, the PDK must be power cycled.
- Your antivirus software might try to scan the MSD part of the
interface MCU. Some antivirus programs trigger a false positive alert in one of the files and
quarantine the unit. If this happens, the interface MCU will become unresponsive.
- If the computer is set up to boot from USB, it can try to boot from the PDK if
the PDK is connected during boot. This can be avoided by unplugging the
PDK before a computer restart, or changing the boot sequence of the computer.
You can also disable the MSD of the kit by using the
msddisable command in J-Link Commander. To enable, use the
msdenable command. These commands take effect after a power cycle of the
PDK and stay this way until changed again.
