Hello all,
I am having problem in updating the code to STM32F103ZCT7 using ST link V2.
I am getting the error as "Can not connect to divice; Internal Command Error"
I am using three pins SWDIO, SWCLK, NRST. 
I have cross check the connections using multimeter & all are OK.
I have not connected AVcc & AVss pins as well as Vbat pins i.e. they are floating, can this create any problem?
Please suggest.
Thanking You all.
