I am trying to program a stm32 G0B1 series board. Most tutorial are using an ST Link to do so but is there a way to do it without one. Here is the picture of board I am using

Hello everyone. I’m trying to build a project that involves 6 PIDs to drive motors of a rover, I’m not much of a programmer so I went with the simulink coder. My boards is nucleo H753ZI and my idea is to have it do the pid loops, the set points of which are to be sent through the ethernet port on the board. So far I’ve hit dead end on the ethernet, I tried settings from the matlab site, yt videos but can’t get it to ping. I put a simple model with sine connected to led pin to verify that the model is working and it works. Has anyone done something with ethernet on the same board in simulink? Where and how can I start the troubleshooting? Also would be great if anyone can share ioc settings, but only if it is for the same board.
