I have made some progress ... I realised I was missing a (clearly rather important !!) item in my .config file, namely CONFIG_TI_DAVINCI_EMAC. I am now able to ping from our board to other systems on the network (again, I've only tested eth0 at the moment). However, I am unable to ping everything I should be able to !!
