Ditto. Ira's suggestion is a very elegant and useful technique ... and has been used successfully for many applications. > We tftp our kernel and boot our board over NFS using the "ethernet" > interface. As Ira suggests, once your target appears as an addressable host, the sky's the limit. You can telnet/ssh into your target, run tftpd, run a web server for configuration/status, etc. Cool stuff!
