System Workbench for STM32

>> Note: When creating a board, you can specify ST-Link version, After that SystemWorkbech will create the custom.cfg for you 😊

Great, I tried launch debug session with this .cfg but I still received the error: ..-+Error erasing flash with vFlashErase packet+-.

OpenOCD log is below. I think there is a problem with reset_config. I have connected stlink and my board only by 4 wires - VCC, SWDIO, SWDCLK and GND. Could it couse the problem?
