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

99: """]]
100: * Next boot, create a new /etc/fstab:
