Short intro to start your DragonBoard 410C with serial console


#1

What you need:

Step by step procedure:

(Do not connect your AC adapter yet.)

  • Connect the USB serial adapter or the Mezzanine to DragonBoard 410C.
    Please, please make sure you have not inserted the adapter misaligned on the LS connector.
    It will destroy the both USB serial adapter and the DragonBoard 410C.
    I know this because I have done this mistake!
  • Connect the MicroUSB cable between your PC and the microUSB connecto on the USB serial adapter or the Mezzanine.
  • Check your DragonBoard 410C is not on top of conductive surface.
    For example, MacBook Air has aluminum surface which will short the circuit and damage the Dragone Board 410C
  • Open serial terminal application on your PC.
    The Linux PC has “minicom”.
    On Windows PC, putty or teraterm are well known. Choose any terminal program.
  • Configure the serial port protocol.
    baud rates 11520
    8N1
    Software flow: OFF
    Hardware flow: OFF
    If the Hardware flow is on, it will hang your screen.
    This is the command line if you are using minicom.

minicom -b 115200 -o -D /dev/ttyUSB0

To turn hardware flow off, change the setting by typing on minicom.
Ctrl-A -> Z, -> O [Configure Minicom] -> Serial Port Setup -> Options F

To turn hardware flow off, change the setting by typing on minicom.
Ctrl-A -> Z, -> O [Configure Minicom] -> Serial Port Setup -> Options G

  • Plug your AC adapter and DC plug converter to DragonBoard 410C.
    You will see no LED on the DragonBoard 410C but do not panic.
    You should able to see the power on LED on the USB adapter or the Mezzanine.
    The boot screen should be showing on your serial console screen.
  • Have fun. :slight_smile:
  • For having more fun, please refer to documentation.

Akira, one suggestion:
If we can add images for connections, etc, it will help understanding the situation clearly.
Picture is worth a thousand words (yeah because it may consume thousand more bytes :wink: )

Hi @sachinpandhare,

Great idea to use images on the instruction on the forum. :slight_smile:

There are many places which pictures would help dramatically.
