I am looking for help with my own PCB design first running process. I have PCB with STM32F407VG and LAN8742A PHY. After powering on, the orange LED is on constantly, and nothing else. I tried it with the program, and the behavior is the same with an erased chip. I have attached schematic parts, clock configuration, and the board state photo.
I will be grateful for any help and suggestions! Thank you so much for your attention and participation.
I tried to set multiple clock configurations, but nothing came up. Maybe I need to add some power sequence at the start of the MCU. I tried many configurations of reset line and the same effect, just nothing. I don't have any idea what I should do more.
The problem has been solved. There was a missing pull-down resistor on one of the lines.
