stm32 Ethernet Error

younginpark · ‎2023-09-26

The problem you are experiencing with your STM32F407IGT6 board is that after programming the firmware and using Ethernet (UDP) communication, if you power it off and then back on, the Ethernet communication doesn't work. However, if you press the Reset button, Ethernet communication becomes operational again. Do you happen to know the reason for this?

Could be getting stuck on startup in some initialization method, perhaps clock initialization. Instrument your code or attach a debugger without resetting to understand where the processor is at when it's stuck and correct.

When entering debugging mode and opening the "start" file, the main screen does not appear. In this state, it is only when you perform a restart (Run -> Restart) that it starts from the "Main.cv" file. Is there a possible connection with this issue? I'm also providing the code for your review. Can you help me investigate this?
