I am developing an application for communicating with the BBB using sockets via the onboard ethernet port.
The strange part is, my client(pc)/server(BBB) application communicated perfectly the first time I ran it, but when I rebooted the BBB, it could not establish an ethernet connection.
I tried pinging the IP given by running “ifconfig” on the BBB 169.254.40.43, but it never replied
I also tried changing to a static IP (192.168.1.80) via this post “http://derekmolloy.ie/set-ip-address-to-be-static-on-the-beaglebone-black/” but I still could not connect.
Finally, I tried this on two different BBB’s one with stock angstrom, one with the newest flash image. Neither could connect. I did not change to static IP on the stock BBB.
I can still connect to usb0, via 192.168.7.2 no problem. In fact I only had a problem with this when I changed eth0 to use static ip 192.168.7.80, somehow this interfered with the 192.168.7.2 IP of usb0 and would not let me ssh into the BBB
Please let me know if I am missing something, I tried rebooting many times and turning eth0 on and off, but I could never establish a connection to it since.
