Target connection fails with "Cannot identify target as a stm32x" (although STM32L053 works)
Hello, glad to hear you succeeded.
The answer is simple, VSSA and VDDA are the Analog supply so it is not only the ADC that needs it, PLL is analog too, and maybe other parts needs it.
And for STlink Utility, it means they don’t activate the PLL to be faster so it is working without the Analog supply.
Rgds,
Laurent
