Installing NetBSD on microSD (arm)

Installing NetBSD on arm arm architecture. First you need to download the image from the NetBSD operating system official site, intended for arm architecture, to any place you like. Then open the console and type the following command:

dd if=armv7.img of=/dev/da4 bs=1m conv=sync

You can add the following at the end to show the process:

status=progress

To write u-boot to the sd card you need to first install either the binary package or the u-boot port on your card. Use the search to find u-boot and then install it:

pkgin install ''u-boot''.  

Then to write u-boot to the sd card run the command using the following example.
This is an example for the Allwinner SoC

dd if=/usr/pkg/share/u-boot/u-boot-sunxi-with-spl.bin/u-boot-sunxi-with-spl.bin of=/dev/rld0d bs=1k seek=8 conv=sync

All done! Now you can insert the SD card into your computer and boot the system with no default root password. To transfer the system to the eMMC internal memory use the guide above or use the sysinst utility.
