Greetings. I am a beginner and an electronic student and I am currently getting my hands on STM32H523. I have created a mcu board in Altium Designer just to control LEDs by GPIO, hopefully to understand more about STM32. I have the PCB fabricated, and the connection for ST Link v2 is SWDIO---SWDIO, SWCLK---SWCLK, GND---GND. I have also connected a wire at the VCC and GND to the 3.3v power supply to power up the MCU. For Boot0, I set it to HIGH since I see people saying that to program the MCU, I need to set it to HIGH.
I have soldered everything and connect the board to st link, and I cannot debug. I was hoping if anyone can give me some guide, and here I will attach my schematic so you may spot out any design errors... Thank you very much, understanding the STM32 means a lot to me as I intend to use them in my future advanced projects.
