Hi everyone, constantly we are getting an error while trying to initialize MSP430F5438 via cp2102. we are using bsl_scripter for initialization of msp430.

Connected pins are shown below:

RXD of CP2102 - TA0.0 (P1.1) of MSP430
TXD of CP2102 - TA0.1 (P1.2) of MSP430
GND & 3.3V of CP2102 - AVcc and Avss of MSP430 (only 2 pins are connected)
DTR of CP2102 - RST pin of MSP430 (with pull-up resistor 47k to 3.3V)
RTS of CP2102 - TEST pin of MSP430

The error shown on the command prompt is shown in the picture:

Do we need to connect all the Vcc and Vss pins of MSP430 or just the Avcc and Avss is enough? Do we also need to connect at least one Dvcc and Dvss?

Thanks in advance.
