I just recieved my BBB . I installed a Virtual box running Ubuntu 14.04.02LTS on a Windows 7 Professional Host
How can I connect to the BBB ?
I would like to coonect to the BBB via serial connection,such that I can see the bootlog of the BBB during boot and such I can stop the bootloader of I want to.
In the VB window where your guest is running, click on Devices → USB → Prolific Technology Inc (or whatever) USB device you want to share to your guest. Once you do that, Ubuntu will “see” the USB connection and automatically create the necessary /dev/ttyUSB0 device.
Then you can use any of the normal tools to open up /dev/ttyUSB0. Screen, minicom, gtkterm, etc.
The scenario you are describing is exactly how I do it as well, so I know it can be done.
