If you can’t connect to the Beaglebone Black via SSH, you can connect with the Beaglebone Black serial port with a USB to FTDI converter to J1. Be sure not to connect the Vdd, 5V, 3.3V or any pin providing voltage to J1!
Beaglebone Black J1 pinout
|4||RX data (connect to TX data of FTDI adapter)|
|5||TX data (connect to RX data of FTDI adapter)|
There is no standard pinout for the USB to FTDI adapters, but the pins are normally labeled on the USB to FTDI adapter board.
- connect the USB to FTDI adapter to your Beaglebone Black (you might use a USB extension cable–I’ve had good luck over the years with the Keyspan USA-19HS)
- open up PuTTY and set the baud rate to 115200 8-N-1 and your COM port to the one you see in Device Manager in Windows or Linux.
- Hit Enter a couple times on your laptop and you should see the login prompt.
