Hi,
I have a beaglebone black which is under ubuntu 14.04 - kernel 4.1.13-ti-r36 installed following the well known eewiki page from Robert C Nelson.
I’ve use few days my beaglebone and, when I upgrade and reboot today, my computer (ubuntu14.04 also) is always looking for connection to the usb/beaglebone (192.168.7.2).
In order to understand what’s happening, I plug an ftdi usb to the serial port : here is what has been returned…
I don’t understand anything except I could not use my bbb until I re-flash my card. I’ve made an iso few days ago so I can easily used it but I’m curious…
Does anyone know what happens?
