4.2 MSP-FET430UIF, MSP-FET, eZ-FET, and eZ-FET Lite

NOTE

The built-in DC-DC converter of the MSP-FET and eZ-FET emulators causes a load-dependent amount of ripple on the output voltage (f_ripple = 1 kHz to 50 kHz, V_{rms_ripple} = 5 mV to 50 mV), which might affect sensitive analog and RF circuits that are supplied by the emulator. For such sensitive circuits, TI recommends temporarily increasing the amount of power supply decoupling used during development, using an emulator with an integrated linear regulator (MSP-FET430UIF or eZ-FET430), or using a separate bench supply.

eZ-FET 2.0 supports LDO mode and can be used for development purposes.

Installation steps for the MSP-FET430UIF, MSP-FET, eZ-FET or eZ-FET Lite:

1. Install the IDE (TI CCS or IAR EW430) before connecting the debug probe to the PC. During IDE installation, the USB drivers for the debug probes are installed automatically. Make sure to use the latest IDE version; older versions might install USB drivers that do not recognize the connected debug probe.
2. Connect the debug probe to a USB port on the PC using the provided USB cable.
3. The following procedure applies to operation under Windows:
   1. After connecting to the PC, the debug probe should be recognized automatically, as the USB device driver has been already installed together with the IDE.
   2. However, if the driver is not automatically detected, the "Found New Hardware wizard" starts. Follow the instructions and point the wizard to the driver files.

   The default location for CCS is: c:\ti\ccsv6\ccs_base\emulation\drivers\msp430\USB_CDC.

   The default location for IAR Embedded Workbench is: <Installation Root>\Embedded Workbench x.x\430\drivers\<Win_OS>.

4. The following procedure applies to operation under Linux:
   • Installation as root
     1. If installing TI CCS as root, make sure that the debug probe is not connected to the computer during installation.
     2. If you start installation with the debug probe connected to the computer, disconnect the probe and reconnect after installation finishes.
   • Installation as user
     1. If installing TI CCS without root access, install the debug probe UDEV rules manually after the CCS TI installation has finished.
     2. Make sure that the debug probe is disconnected from the computer during this step.
     3. Open the shell and go to: <CSS installation directory>/ccsv7/install_scripts.sh
     4. Execute msp430uif_install.sh as sudo.
     5. Connect the debug probe and make sure that the debug probe is detected as other than "modem". Use the dmseg command to check the system log.
     6. The debug probe is ready for use.
5. After connecting the debug probe to a PC, the probe performs a self-test. If the self-test passes, the green LED stays on. For a complete list of LED signals, see the LED Signals section of each debug probe in Section 5.6 through Section 5.8.
6. Connect the debug probe with the target board using the 14-pin ribbon cable.
7. When using a target socket board, make sure that the MSP430 MCU is properly inserted in the socket and that pin 1 of the device (indicated with a circular indentation on the top surface) aligns with the "1" mark on the PCB.

NOTE

To use the debug probe without an IDE, install the stand-alone driver package. The stand-alone driver installer can be found at www.ti.com/mspds under the heading MSPDS-USB-DRIVERS.
