Hi Pratiksha, This is a common error that indicates a physical hardware connection failure between the eZ-FET lite and target board. It is centered around the 2-wire JTAG (SBW) communication best explained by Figure 2-3 of the MSP430 Hardware Tools User's Guide (SLAU278): www.ti.com/.../slau278y.pdf You require four connections: VCC, GND, TST, and RST. They must all come from the eZ-FET lite side of the MSP-EXP430F5529LP and be as short as possible going to the MSP430F5528 . You will also need an external 47 kOhm pullup resistor and 2.2 nF pulldown capacitor on the RST line. There are several similar threads on the MSP E2E that you can reference to solve your problem. Regards, Ryan
