1.2 jasper 42: The current target platforms are Allwinner A1x/A20 (<tt>sunxi</tt>),
43: Freescale i.MX6 (<tt>imx</tt>) and TI OMAP3/4
44: (<tt>am335x</tt>/<tt>beagle</tt>/<tt>panda</tt>). We try to support
45: most of the boards based on those SoCs. A list of supported boards
46: is in the section <a href="#hardware">Supported hardware</a>.
47: </p>
48:
49: <p>
50: There are generally still a fair number of things to do on each of
1.8 jmc 51: these boards, however OpenBSD is generally considered to be usable on
1.2 jasper 52: them.
1.1 patrick 53: The platform is now self hosting, however there is no SMP support.
1.5 rapha 54: Networking is working on <tt>am335x</tt>, <tt>imx</tt>, <tt>panda</tt>
1.2 jasper 55: and <tt>sunxi</tt>.

63: <p>
64: A note on the platforms and the associated boards; OpenBSD/armv7
65: bundles various platforms sharing the ARM v7 architecture. Due to the
1.5 rapha 66: fact that there are many System on a Chips (SoC) around,
67: OpenBSD/armv7 differentiates between various SoCs and may have a
1.2 jasper 68: different level of support between them. All devices based on the
69: i.MX6 are refered to as <tt>imx</tt>, all devices based on A1x/A20 are
70: refered to as <tt>sunxi</tt>. The boards with an OMAP 3/4 SoC are
1.5 rapha 71: subdivided into <tt>am335x</tt> (for BeagleBone), <tt>beagle</tt> (for
1.2 jasper 72: BeagleBoard) and <tt>panda</tt> (for PandaBoard).

! 128: <b>Building from source:</b>
! 129: At this moment, the kernel has to be in the FAT boot partition, not the
! 130: root of the file system like other OpenBSD platforms, and this kernel
! 131: must be in a format required by the U-Boot boot loader.
! 132: So, after building your kernel, you must go through some special steps:
! 133:
! 134: <blockquote><pre>
! 135: # <b>config GENERIC</b>
! 136: # <b>cd ../compile/GENERIC</b>
! 137: # <b>make clean; make</b>
! 138: # <b>make bsd.OMAP.umg</b>
! 139: # <b>mount /dev/sd0i /mnt</b> <i># assuming your FAT partition is 'i'</i>
! 140: # <b>cp bsd.OMAP.umg /mnt/bsd.umg</b>
! 141: </pre></blockquote>
! 142:
! 143: <b>No real time clock:</b> Many of the armv7 devices do not have a
! 144: battery backed real time clock.
! 145: For this reason, using the "-s" option of
! 146: <a href="faq/faq6.html#OpenNTPD">OpenNTPD</a> may be desirable.
! 147:
! 148: <p>
! 149: <b>Distribution kernels must be converted before use:</b>
! 150: The distribution kernels are standard kernels, which can be used
! 151: for the <tt>-N</tt> option of
! 152: <a href="http://man.openbsd.org/?query=ps">ps(1)</a>,
! 153: <a href="http://man.openbsd.org/?query=vmstat">vmstat(8)</a>,
! 154: <a href="http://man.openbsd.org/?query=dmesg">dmesg(8)</a>,
! 155: <a href="http://man.openbsd.org/?query=iostat">iostat(8)</a>
! 156: and similar applications, but cannot be booted directly by the U-Boot
! 157: bootloader used on this platform.
! 158:
! 159: This can be done using
! 160: <a href="http://man.openbsd.org/?query=mkuboot">mkuboot(8)</a>
! 161:
! 162: <p>
! 163: Typical operation is something along these lines for OMAP/beagle:
! 164:
! 165: <blockquote><pre>
! 166: # <b>mkuboot -a arm -o linux -e 0x80300000 -l 0x80300000 <i>bsd</i> bsd.umg</b>
! 167: </pre></blockquote>
! 168:
! 169: for i.MX6:
! 170:
! 171: <blockquote><pre>
! 172: # <b>mkuboot -a arm -o linux -e 0x10300000 -l 0x10300000 <i>bsd</i> bsd.umg</b>
! 173: </pre></blockquote>
! 174:
! 175: where <i>bsd</i> is the name of the kernel you are converting.
! 176:
! 177: <p>
! 178: <b>U-Boot tricks:</b>
! 179: <ul>
! 180: <li>Booting single user (OMAP/beagle):
! 181:
! 182: <blockquote><pre>
! 183: U-Boot# mmc rescan
! 184: U-Boot# setenv bootargs sd0 -s
! 185: U-Boot# fatload mmc 0 0x82800000 bsd.umg
! 186: U-Boot# bootm 0x82800000
! 187: </pre></blockquote>
! 188:
! 189: <li>Booting single user (i.MX6, mmc storage):
! 190:
! 191: <blockquote><pre>
! 192: U-Boot# mmc rescan
! 193: U-Boot# setenv bootargs sd0 -s
! 194: U-Boot# fatload mmc 0 0x12000000 bsd.umg
! 195: U-Boot# bootm 0x12000000
! 196: </pre></blockquote>
! 197:
! 198: <li>Booting single user (i.MX6, SATA storage):
! 199:
! 200: <blockquote><pre>
! 201: U-Boot# sata init
! 202: U-Boot# setenv bootargs sd0 -s
! 203: U-Boot# fatload sata 0 0x12000000 bsd.umg
! 204: U-Boot# bootm 0x12000000
