How to Start Odinub with Mac OS

I wanted to set it up, but I didn’t have a keyboard, mouse, or monitor I could attach to it. I thought I could attach my Odinub to my Mac via Ethernet, and SSH would “just work," but it didn’t. After a few hours of googling, I found a solution. This guide shows you how you guys can connect your Odinub with mac in just 4-5 steps:

Step 1: Required Materials:

• Odinub
• MicroSD Card
• USB to Serial Converter
• Jumper Wires

Now, if we want to connect Odinub headless we can use UART protocol.

Step 2: Hardware Connection:

Connect your serial converter to Odinub.

Here we are using UART protocol so we have to connect 3 pins.

Connection:

Usb to Serial Converter pins: Odinub Debugger Pins:

GND(1 pin) GND

TX (Transmit 5 pin) RX (Transmit pin)

RX (Transmit 4 pin) TX (Transmit pin)

Step 3: Set Up the Serial Terminal on Mac:

Now open the terminal on your Mac fire the below command

ls /dev/cu.usbserial-*  

You will find the device name is /dev/cu.usbserial-A9M9DV3R

Step 4: After Step 3, You Will Find Out the Unique Serial Number

Note that number and fire the below command.

screen /dev/xx.usbserial-XXXXXXXX 115200 –L  

where /dev/xx.usbserial-XXXXXXXX is replaced by your device unique name. Using the example above, the command would be:

screen -L /dev/cu.usbserial- A9M9DV3R 115200 –L  

After executing the upper command, you will find out the black screen. At the blank screen, press Enter twice. A login screen is displayed.

Step 5: At the Login Prompt, Type Root and Press Enter

Press Enter when prompted for a password(root). The following screen is displayed:

You have now established a serial communication with your board. You can interact with your board by entering common Linux commands.
