Hi all, Is it feasible to send u-boot commands via Ethernet instead of UART? I know that there is no such support right now. But can it be added? Moreover how am I supposed to transmit UDP or TCP packets from u-boot?
Look into netconsole for control over Ethernet. I haven't used it personally, but it's supported in U-boot.
What kind of UDP or TCP packets do you want to send? Many of the common UDP-based protocols have some support (NFS, TFTP and some others), but keep in mind that U-boot is not a multitasking environment and so there is no concept of 'servers'. Apart from netconsole, all network communications must start from the target.
