30: # Installation
31:
32: * Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beagleboard.img*
33: * Build U-Boot for ODROID-C1 <https://github.com/hardkernel/u-boot/tree/odroidc-v2011.03>
1.3 wiki 34: * Pre-built binaries here: <http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/odroidc1/u-boot-odroidc-v2011.03-20150308.tar.gz>
1.4 wiki 35: * Note the location and size of the FFS partition in the *beagleboard.img* disklabel:
36: [[!template id=programlisting text="""
37: # $TOOLDIR/bin/nbdisklabel -M evbarm -B le beagleboard.img
38: ...
39: 8 partitions:
40: # size offset fstype [fsize bsize cpg/sgs]
41: a: 1359312 385024 4.2BSD 0 0 0 # (Cyl. 188 - 851*)
42: b: 262144 122880 swap # (Cyl. 60 - 187)
43: c: 1744336 0 unused 0 0 # (Cyl. 0 - 851*)
44: d: 1744336 0 unused 0 0 # (Cyl. 0 - 851*)
45: e: 114688 8192 MSDOS # (Cyl. 4 - 59)
46: """]]
1.2 wiki 47: * Write the bootloader to the empty space at the start of the base image:
48: [[!template id=programlisting text="""
49: # dd if=bl1.bin.hardkernel of=beagleboard.img bs=1 count=442 conv=notrunc
50: # dd if=bl1.bin.hardkernel of=beagleboard.img bs=512 skip=1 seek=1 conv=notrunc
51: # dd if=u-boot.bin of=beagleboard.img bs=512 seek=64 conv=notrunc
52: """]]
1.4 wiki 53: * Since the bootloader has overwritten the disklabel, we need to re-add partition "a" from the disklabel to the MBR partition table:
54: [[!template id=programlisting text="""
55: # $TOOLDIR/bin/armv7--netbsdelf-eabihf-fdisk -u beagleboard.img
56: ...
57: Which partition do you want to change?: [none] 1
58: The data for partition 1 is:
59: <UNUSED>
60: sysid: [0..255 default: 169]
61: start: [0..109cyl default: 63, 0cyl, 0MB] 385024
62: size: [0..85cyl default: 1359312, 85cyl, 664MB] 1359312
63: ...
64: Which partition do you want to change?: [none]
65: ...
66: Should we write new partition table? [n] y
67: """]]
1.2 wiki 68: * Write the image to an SD card.
69: * Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition on the SD card.
70: * Create or edit boot.ini on the MS-DOS partition:
71: [[!template id=programlisting text="""
72: ODROIDC-UBOOT-CONFIG
73:
74: setenv m "1080p"
75: setenv vout_mode "hdmi"
76: setenv m_bpp "32"
77: setenv disableuhs "disableuhs"
1.4 wiki 78: setenv bootargs "root=ld0f awge0.mac-address=${ethaddr}"
1.2 wiki 79: setenv bootcmd "fatload mmc 0:1 0x21000000 netbsd.ub; bootm 0x21000000"
80: run bootcmd
81: """]]
1.5 wiki 82: * On first boot, it will stop because of the wrong device in /etc/fstab. Take this opportunity to grow the root file-system:
1.4 wiki 83: [[!template id=programlisting text="""
84: # fdisk -u ld0

86: Which partition do you want to change?: [none] 1

101: * Next boot, create a new /etc/fstab:
