1700 +How to build a ramdisk image for use as a root filesystem with AR531X
1701 +
1702 +Overview:
1703 +In order to boot from a ramdisk root file system image, you will
1704 +first create a root directory structure in the "rootdir" directory.
1705 +Then run "make" to create a compressed root file system image in
1706 +ramdisk.gz. Finally, copy this image into your kernel source tree
1707 +and remake the kernel. The ramdisk image is then built into the
1708 +kernel. When the kernel starts, it is uncompressed into RAM, and
1709 +used as a root file system.
1710 +
1711 +If you'd like to use a pre-built ramdisk.gz rather than build
1712 +one yourself:
1713 + cp arch/mips/ar531x/RAMDISK/ramdisk.gz arch/mips/ramdisk/ramdisk.gz
1714 +
1715 +Here are the detailed steps to build your own:
1716 +
1717 +1) Modify Makefile to point KERNEL_SOURCE at your linux source tree.
1718 +
1719 +2) Copy whatever additional files/directories/links you'd like to
1720 + under rootdir. Note that you're limited to CONFIG_BLK_DEV_RAM_SIZE
1721 + 1KB blocks, as specified in your linux/.config file.
1722 + Examples:
1723 + Copy busybox to rootdir/bin/
1724 + [NOTE: Copy busybox.links to this directory to
1725 + cause the makelinks script to automatically
1726 + set up all of the necessary busybox command links
1727 + in the rootdir/bin directory].
1728 +
1729 + Copy any wireless driver modules into rootdir tree
1730 +
1731 + You might want to make a copy of the rootdir directory
1732 + before you modify it, just in case you want to get back
1733 + to the original.
1734 +
1735 +3) LOGIN AS ROOT (e.g. "su") and type "make"
1736 +
1737 +4) Copy the resulting ramdisk.gz to your linux source tree under
1738 + arch/mips/ramdisk/ramdisk.gz
1739 + (or "make install" will do this step for you)

2127 +Basic information for the AR531X Board Support Package
2128 +
2129 +This directory contains the "LBSP" -- Linux Board Support Package --
2130 +for Linux on the Atheros AR531X Wireless System-On-a-Chip. It is intended
2131 +primarily as a building block for wireless products. At this time, the
2132 +AR531X Linux BSP is experimental code, and is actively UNDER CONSTRUCTION.
2133 +
2134 +Some components that are supported by this LBSP along with a standard 2.4
2135 +Linux MIPS kernel include
2136 + R4Kc CPU
2137 + instruction and data caches
2138 + SDRAM
2139 + flash (Macronix, AMD, STS, etc.)
2140 + 16550 serial port

2143 + General-Purpose I/O pins
2144 + kernel debugging with kgdb
2145 +
2146 +This LBSP code does NOT include drivers for the wireless components of the
2147 +chip/boards! Drivers for those components may be distributed separately.
2148 +In particular, the MADWiFi project under SourceForge supports (not yet!)
2149 +wireless functions on the AR531X chipset. See
2150 + http://www.sourceforge.net/projects/madwifi

2185 + -You can use an ICE (e.g. VisionICE) to load the vmlinux image. You will
2186 + need appropriate register initialization (e.g. AP30.ini file)
2187 + -You can use the eCos RedBoot bootrom loader. This is a full-featured
2188 + bootrom which as been ported to AR531x. It can boot vmlinux over ethernet
2189 + or from flash. Source code is available from Atheros.

2191 +Please send comments, corrections, complaints, criticisms, suggestions,
2192 +enhancements, requests, or any other reasonable communications regarding
2193 +this effort, to "linux@atheros.com". Your email will be received by a

2199 + How to BUILD a linux kernel for an AR531X system
2200 +
2201 +It is expected that you will build Linux on an existing Linux system, which
2202 +has all of the standard Linux tools.
2203 +
2204 +01) Obtain a MIPS BigEndian ELF gcc-compatible toolchain. For example,
2205 + if you're cross-compiling on a x86 Linux system, you could use:
2206 + ftp://ftp.mips.com/pub/tools/software/sde-for-linux/sdelinux-5.01-4eb.i386.rpm
2207 +
2208 +02) Obtain the latest working MIPS Linux kernel
2209 + cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs login (password "cvs")
2210 + cvs -d :pserver:cvs@ftp.linux-mips.org:/home/cvs co -r linux_2_4 linux
2211 +
2212 + Now "cd linux". The remainder of these instructions assume
2213 + that you are in the linux directory.
2214 +
2215 +03) Place the contents of this directory at arch/mips/ar531x.
2216 +
2217 +04) Use the patch command to patch generic linux files according
2218 + to the DIFFS directory
2219 + for i in arch/mips/ar531x/DIFFS/*.diff
2220 + do
2221 + patch -p1 < $i
2222 + done
2223 + NOTE: This version of the AR531X Linux BSP was tested with
2224 + MIPS Linux 2.4.22 as of 11/14/03. If you use a different
2225 + (e.g. more recent) version of Linux source, you may need to
2226 + resolve some minor patch and compilation issues.
2227 +
2228 +05) Set up a RAMDISK image.
2229 + See the instructions in README.RAMDISK.
2230 +
2231 +06) Set up a linux configuration using ar531x/defconfig-ar531x.
2232 + cp arch/mips/ar531x/defconfig-ar531x .config
2233 + make oldconfig (answer all questions that are asked)
2234 + NOTE: For development/debug purposes, you may want to
2235 + enable CONFIG_RUNTIME_DEBUG and CONFIG_KGDB.
2236 +
2237 +07) Make dependencies.
2238 + make dep
2239 +
2240 +08) Build the linux kernel
2241 + make
2242 +
2243 +09) The linux image you just built is in vmlinux.
2244 + See instructions in README.EXECUTE to run your vmlinux

2250 + How to EXECUTE a linux image on an AR531X system
2251 +
2252 +There are currently three ways to run you vmlinux image:
2253 + 1) Load it using the vxWorks bootrom that is supplied with the board.
2254 + You can load it over ethernet or from the TFFS file system, if you
2255 + have sufficient flash to store the image.
2256 + 2) Load it using an ICE (e.g. VisionICE).
2257 + 3) Use a bootrom loader, such as eCos RedBoot.
2258 +
2259 +After you have booted linux:
2260 + By default, the root filesystem on ramdisk is read-only.
2261 + To make it writable, use "mount -o remount w /".
2262 +
2263 + The user-level commands are slightly non-standard, as they
2264 + are based on "busybox".
2265 +
2266 + The "wget" command is included. You can use wget to fetch
2267 + files from any ftp server. So, for instance, you can fetch
2268 + a kernel module and then "insmod" it.
2269 +
2270 +Note that the standard source-level kernel debugger, kgdb, works well
2271 +over the serial line with this port. We use kgdb and the kgdb_demux perl
2272 +script -- available over the www -- for debugging.
