MSP430FR2355 LaunchPad™ Development Kit (MSP ‑ EXP430FR2355)
2.2.2 eZ-FET Onboard Debug Probe With EnergyTrace™ Technology
To keep development easy and cost effective, TI’s LaunchPad development kits integrate an onboard
debug probe, which eliminates the need for expensive programmers. The MSP-EXP430FR2355 has the
eZ-FET debug probe (see Figure 5), which is a simple and low-cost debugger that supports all MSP430™
device derivatives.

The MSP-EXP430FR2355 LaunchPad development kit features EnergyTrace technology but does not
have support for EnergyTrace++ technology. The EnergyTrace technology functionality varies across the
MSP portfolio.

The dotted line through J101 shown in Figure 5 divides the eZ-FET debug probe from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. More
details on the isolation jumper block are in Section 2.2.3.
The eZ-FET also provides a "backchannel" UART-over-USB connection with the host, which can be very
useful during debugging and for easy communication with a PC. More details can be found in
Section 2.2.4.
The eZ-FET hardware can be found in the schematics in Section 6 and in the hardware design files
download page. The software and more information about the debugger can be found on the eZ-FET wiki.
