# Installation
* Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beagleboard.img*
* Build U-Boot for ODROID-C1 <https://github.com/hardkernel/u-boot/tree/odroidc-v2011.03>
* Pre-built binaries here: <http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/odroidc1/u-boot-odroidc-v2011.03-20150308.tar.gz>
* Write the bootloader to the empty space at the start of the base image:
[[!template id=programlisting text="""
# dd if=bl1.bin.hardkernel of=beagleboard.img bs=1 count=442 conv=notrunc
# dd if=bl1.bin.hardkernel of=beagleboard.img bs=512 skip=1 seek=1 conv=notrunc
# dd if=u-boot.bin of=beagleboard.img bs=512 seek=64 conv=notrunc
"""]]
* Write the image to an SD card.
* Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition on the SD card.
* Create or edit boot.ini on the MS-DOS partition:
[[!template id=programlisting text="""
ODROIDC-UBOOT-CONFIG
setenv m "1080p"
setenv vout_mode "hdmi"
setenv m_bpp "32"
setenv disableuhs "disableuhs"
setenv bootargs "root=ld0a awge0.mac-address=${ethaddr}"
setenv bootcmd "fatload mmc 0:1 0x21000000 netbsd.ub; bootm 0x21000000"
run bootcmd
