2.6.1.1
Run Code
Follow these steps to verify correct operation of the example code:
1. Plug the FX3 board into a USB host port using the provided cable. You can use any speed USB
port, but eventually you will want to plug into a USB 3.0 port to study and test FX3 SuperSpeed
applications.
2. Move the slide switch (
SW9
) in the lower right corner of the board to the UP position. This sup-
plies board power from USB, eliminating the need for an external power unit.
3. The board enumerates as a
Cypress BootLoader
, as seen in the
Device Manager
tree
(
Figure 2-16
).
Figure 2-16. FX3 Board appears as BootLoader
If the board appears as
WestBridge
or as an
unknown device
in the Device Manager, right-click
the entry, navigate to the bin folder in your EZ-USB FX3 SDK installation, and select your
operating system folder. These steps are shown in
Manual Installation of Cypress Driver on
page 39
of this document.
