I have a Picozed 7030 SOM board on a FMC Carrier Card V2. When I enable Dropbear in the petalinux build, ethernet works on it using ifconfig & ping. This is through the Ethernet port. Instead of ethernet, I am using fiber optic cable with SFP+ connector on the board now. The cable is detected by the board as the corresponding LED lights up. But ifconfig doesn't show the connection. What do I need to enable in the Petalinux build procedure so that the fiber-optic connection is detected when I try ifconfig on the linux system? Alternatively, what are my options? Thanks in advance.
