Reprogramming the USB TAP Firmware
Image
At some point you may be required to reprogram the USB TAP firmware image stored in
its flash EPROM. To do this:
1. Make sure the USB TAP is connected to a USB Port on your host computer.
2. Launch CCS and open the CCS command window. The procedure is slightly different
on Windows and Linux host machines.
• For Windows:
Run the command:
<CodeWarrior Installation>\ccs\bin\ccs.exe
This will launch CCS and add a CCS icon ( Figure F.1 ) to your taskbar. Double-
click that icon in the taskbar to open the command window.
• For Linux
Run the command:
<CodeWarrior Installation>/ccs/bin/ccs
This will launch CCS and open the command window automatically.

3. In the CCS Command window, enter the command:
updateutap <serial_number>
The <serial_number> parameter should be the serial number of your USB TAP,
which is on the bottom of the device. If you have only one USB TAP connected to
your host machine, you do not need to specify the
<serial_number> parameter.
You should see the output displayed in Listing F.1 (although the version number may
be different).

*** WARNING ***
DO NOT UNPLUG YOUR USB TAP: Doing so will render your USB
TAP non-functional and require factory reprogramming.
