Debug Hints and Trouble Shooting
1. If installing on Windows XP and your PC is connected
to the internet through a firewall the USB install may
take up to 15 minutes if you let it complete normally.
The work-around for this issue is to simply disconnect
your network cable during the USB hardware install.
2. Some of the Help Files are links to Adobe Acrobat
PDF files. If you intend to access these files you must
have Adobe Acrobat installed on your system.
3. If you want to verify a successful USB driver install,
open your device manager by right clicking on the My
Computer icon on your desktop and selecting
Properties --> HW --> Device Manager. You should
see a new class “SD USB Based Debug Tools” and
one Spectrum Digital TMS320F28xx eZdsp installed.
4. The DS201 LED comes on when power is applied to
the eZdsp. Do not launch Code Composer until the
LED is off.

troubleshooting and software
