I have CDC-ECM working just fine to my Linux machine. Ping now working too.
I cannot get RNDIS to work. It is seen by Windows and has an IP, but pings in either direction fail. If I ping from my board to the windows machine I get: arp_send: ERROR: arp_wait failed: -110 Looks like arp is failing for some reason but I have no idea, despite having compared defconfig files that have RNDIS enabled :( >-----Original Message----- >From: Alan C.
