I designed new board with STM32WB55CGU6 based on MB1993C (P-NUCLEO-USBDongle). You can see my schematic attached(I uploaded both P-nucleo schematic and my schematic). But I can't connect to my MCU through SWD pins (DIO,CLK,NRST). I use st-link, I can connect to P-nucleo usbdongle with these 3 pins, but I can't connect to my MCU. ST-Link can't find MCU. Unfortunately one of the crystals in my design (which is connected to pins number 23 and 24) has wrong footprint, but at least I should be able to connect to the MCU. does anyone know what is the problem?
