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! The pins you want to use on the Beaglebone Black J1 are:
|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.
