I am a beginner in electronics. I recently designed a board using the STM32F407VGT6 and DP83848, but after assembly and testing, I encountered a problem.
The board can be programmed and it runs, but the Ethernet section does not work properly.
It does not obtain an IP address.
And the Ethernet LED(pin 26) turns on and off occasionally , but the Ethernet connection is not actually established.
I would appreciate it if you could guide me regarding the schematic and circuit so I can solve this issue.
