I have demoboard and it has an u-boot. In u-boot, I want to send command through ethernet rather than serial port(Like bootm 0x20000000 0x70000000). Actually, I want to use ethernet rather than serial port. Is this possible? If so, what should I do?
You need to provide much more details such as what board you're using and if you're using mainline U-Boot or some vendor tree. But the general answer is that yes, you can. See https://docs.u-boot.org/en/latest/usage/netconsole.html for more details on how to use netconsole.
