Hi!

First of all. Did you install the USB-connection driver for your F28335_eZdsp? Have this driver been installed correctly? Attach your device to USB of PC and power-on device. Look at the System device maneger of PC. Find your new USB-connection. If you can not find it then try reinstall driver.

Igor

Hi!

What did you install the first: CCS or eZdsp28335 Drivers? Try uninstall all. Install CCS furst and then eZdsp28335 Drivers.
