I have been trying to program my STM32L476RG micro-controller based breakout board using ST-LINK v2 as the programmer. I have hooked every VDD of breakout board to 3.3 V pin of programmer and connected VSS of breakout board to ground.
Also, I've connected SWCLK and SWDIO respectively. But every time I try to connect it in ST-LINK Utility it is initially giving me "Can not connect to target ST-LINK. After I reset it is giving "USB Communication Error" and same error thereafter.
I have tried using solutions presented in Patrick Hood-Daniel tutorial and also pulling up the BOOT0 pin but neither seem to work.
Any suggestions on this problem will be of much help.
