1. Are both power LEDs lit The board has two power domains because of the isolated JTAG interface For low voltage application development JTAG isolation is not needed and the power domains can be combined to allow for convenience that is the board can be powered completely through the USB Ensure that jumpers are placed on the posts of JP1 JP2 and JP3 Are drivers correctly installed for the XDS100v2 present on the LaunchPad Right click on My Computer and select properties Navigate to the Hardware tab in the dialog box and open the device manager Scroll to the bottom of the list and expand the USB Serial Bus controllers item Are there two entries for TI XDS100 Channel A B If not try unplugging and replugging in the board Does Windows give you any messages in the system tray In Device Manger do either of the entries have a yellow exclamation mark over their icon If so try reinstalling the drivers Why is the serial connection not working There are a few things that could cause this and they are easy to fix s S4 in the up position S4 connects the F28027 device serial peripheral to the XDS100 serial port so this switch must be turned on up for serial connectivity to function Are you using the correct COM port Right click on My Computer and select properties Navigate to the Hardware tab in the dialog box and open the device manager Scroll to Ports COM amp LPT and expand this entry Is there a USB Serial P2. 1 Can other programming and debug tools such as an XDS510 emulator be used with the C2000 LaunchPad While a user could potentially connect an external emulator to the F28027 device present on the LaunchPad it would require some rework of the board It is recommended that users who want to use an external emulator purchase a controlCard and docking station that includes an external JTAG connector What versions of Code Composer Studio can be used to develop software for the C2000 LaunchPad It is highly recommend that novice users develop applications with Code Composer Studio v5 The drivers examples and other associated software are tailored to make the user experience as smooth as possible in Code Composer Studio v5 However there is nothing to prevent a user from creating projects in Code Composer Studio v3 or v4 with the source files available in controlSUITE Keep in mind that all the projects for the C2000 LaunchPad are Code Composer Studio v5 projects and will not import into Code Composer Studio v3 or v4 Only expert users should attempt to use the LaunchPad with Code Composer Studio v3 or v4 Why can t connect to the LaunchPad in Code Composer Studio There are a number of things that could cause this and they all have an easy fix e Is S1 switch 3 in the down position This is the TRST pin that enables and disables JTAG functionality on the chip This switch must be in the up position for the emulator to be able to connect
