Installation

Preparation

The device uses u-boot with petitboot loader loaded in spi memory. Installation to eMMC was tested:

 pmbootstrap build linux-odroid-n2plus
 pmbootstrap build device-odroid-n2plus

Put an eMMC card into eMMC-to-USB3 reader, assumption is it appears as /dev/sdX (replace sdX with correct devicename below), and install to it:

 pmbootstrap install --sdcard /dev/sdX

Afterwards, still this manual step is needed to create u-boot compatible initramfs:

 mount /dev/sdX1 /mnt/boot && \
 cd /mnt/boot && \
 mkimage -A arm64 -T ramdisk -C none -n initramfs -d initramfs initramfs.uimg
