Installation
This device package is compatible with odroid-u3 as well |
1. Use pmbootstrap to create a bootable SD card:
pmbootstrap init # pick 'odroid' as manufacturer, 'u2' as device. pmbootstrap install --sdcard=/dev/sdX
You can choose between using Alpine Linux's linux-lts kernel, or PostmarketOS's linux-postmarketos-exynos4PMOS kernel. Both work rather well.
You must install the nonfree firmware package for this device to get it booting. It contains early bootloaders which initialise the hardware and then boot u-boot.
2. Insert SD card or eMMC card into the Odroid U2, plug in the Ethernet cable and turn it on.
3. The Odroid U2 should boot up, get an ip address, and become accessible over SSH.
If the Odroid does not appear on your local network, its Ethernet may be disabled. One can enable it by attaching a keyboard and following the Alpine wiki: sudo setup-interfaces && sudo /etc/init.d/networking --quiet restart && sudo rc-update add networking boot. Ethernet also will not work if the system time is too out of date. It should sync automatically, but if that process is too slow you might want to manually edit the date and time. |
