| - | ===== Prerequisites ===== | + | This is a step-by-step guide of how to test ODROID boards. It assumes that you want to run "headless", that is, access it via network connections without a keyboard or display. This guide is based on Hardkernel's Ubuntu environment. |
| + | |||
| + | ===== Assumetions ===== | ||
| + | You **HAVE**: | ||
| + | * ODROID-XU4 | ||
| + | * SD card //or// eMMC (installed Ubuntu) | ||
| + | * Ethernet cable | ||
| + | * Linux PC | ||
| + | * A switching hub | ||
| + | * DHCP network | ||
| + | |||
| + | You do **NOT** have: | ||
| + | * USB keyboard | ||
| + | * USB-UART Module Kit | ||
| + | * HDMI cable/monitor | ||
| + | | ||
| ===== Boot the ODROID and find IP address ===== | ===== Boot the ODROID and find IP address ===== | ||
| + | Connect the ODROID to a spare Ethernet port on your switching hub using an Ethernet cable. | ||
| + | |||
| + | Insert the SD card(or eMMC) into the ODROID-XU4. | ||
| + | |||
| + | Turn on the ODROID-XU4. Wait about 30 seconds. | ||
| + | |||
| + | Ping scan to update ARP table: | ||
| + | <code> | ||
| + | brian@brian-desktop:~$ nmap -sn 192.168.100.0/24 | ||
| + | |||
| + | Starting Nmap 7.01 ( https://nmap.org ) at 2016-05-17 15:09 KST | ||
| + | Nmap scan report for 192.168.100.1 | ||
| + | Host is up (0.00066s latency). | ||
| + | Nmap scan report for 192.168.100.2 | ||
| + | Host is up (0.000084s latency). | ||
| + | Nmap scan report for 192.168.100.3 | ||
| + | Host is up (0.00046s latency). | ||
| + | Nmap scan report for 192.168.100.53 | ||
| + | Host is up (0.00066s latency). | ||
| + | Nmap scan report for 192.168.100.68 | ||
| + | Host is up (0.095s latency). | ||
| + | Nmap done: 256 IP addresses (5 hosts up) scanned in 2.43 seconds | ||
| + | brian@brian-desktop:~$ | ||
| + | </code> | ||
| + | |||
| + | Check the ODROID-XU4 IP address: (NOTE: "00:1e:06" is start MAC address for ODROID boards.) | ||
| + | <code> | ||
| + | brian@brian-desktop:~$ arp -a | grep 00:1e:06 | ||
| + | ? (192.168.100.53) at 00:1e:06:33:0d:45 [ether] on enp0s25 | ||
| + | brian@brian-desktop:~$ | ||
| + | </code> | ||
| + | |||
| ===== Login using ssh ===== | ===== Login using ssh ===== | ||
| + | In a terminal in your Linux PC, type "ssh odroid@xxx.xxx.xxx.xxx", where "xxx.xxx.xxx.xxx" is the IP address you discovered in the previous step. | ||
| + | |||
| + | It will then prompt for your password. Type in the default password **odroid**: | ||
| + | |||
| + | <code> | ||
| + | brian@brian-desktop:~$ ssh odroid@192.168.100.8 | ||
