Question
Voltage problem on VDD pin on SWD connector.
It's my first design with a STM32 MCU. I want to program a MCU on my custom board with the ST-LINK but when I try with STM32 ST-LINK Utility the connection doesn't work. The STM isn't recognized. When I measure VCC signal on the connector SWD I have only 0.79 V instead of 3.3V.
Someone can explain me what is the problem or what I'm doing wrong ?
