This document describes how to build the source code for the silex SX-560.

The following tarballs are included:

u-boot-1.2.tar.bz2      		Das U-Boot V1.2 the Universal Boot Loader
s3c-linux-2.16.11.tar.bz2		Linux kernel for Samsung S3C2412
buildroot-snapshot.tar.bz2		Buildroot snapshot
busybox-1.10.4.tar.bz2			Busybox tools V1.10.4
net-snmp-5.4.2-pre2.tar.bz2		SNMP libraries
openssl-0.9.8g.tar.bz2			OpenSSL
buildroot-downloads.tar.bz2		uClibc, binutils, gcc, etc.
buildroot.config			configuration file for buildroot

Note that buildroot-downloads.tar.bz2 is not required because buildroot will
download what it needs automatically. But buildroot-downloads.tar.bz2 does
include the source to uclibc so we make it available per the license.


1. Cross compiler and tools

   ** You may need to install ncurses-devel package if menuconfig fails to build
   ** You need write access to /opt directory

   tar -xf buildroot-snapshot.tar.bz2
   tar -xf buildroot-downloads.tar.bz2
   mv buildroot-downloads buildroot/dl
   cp buildroot.config buildroot/.config
   cd buildroot
   make menuconfig
   (Make changes as needed, installs to /opt/tools/uclibc by default)
   make

2. Update environment to use new tools

   export PATH="$PATH:/opt/tools/uclibc/bin"
   export CROSS_COMPILE=arm-linux-
   export CROSS=arm-linux-
   export KERNEL=<insert path to kernel directory>
   export DEVROOT=<insert path to root development directory>

3. Bootloader

   tar -xf u-boot-1.2.0.tar.bz2
   cd u-boot-1.2.0
   make

4. Busybox
   ** Note that busybox built by buildroot is not used on the SX-560
   tar -xf busybox-1.10.4.tar.bz2
   cd busybox-1.10.4
   make

5. MTD utils (needed only if updating kernel)
   tar -xf mtd-utils.tar.gz
   cd mtd-utils
   make
   ** Will die with an error, but builds flash_eraseall successfully which is all that we need **
   ** flash_eraseall lives in arm-linux directory **

6. Kernel

   tar -xf s3c-linux-2.6.16
   cd s3c-linux-2.6.16
   ** Start with default configuration for SX-560
   cp arch/arm/configs/sx560_defconfig .config
   ** Make any changes needed
   make menuconfig
   make

   cd arch/arm/boot
   ** The following script needs u-boot-1.2.0/tools/mkimage in your path **
   ** If you didn't build the bootloader above, mkimage won't be built **
   ./mkkern.sh
   ** new kernel is zImage.img and is in a format that u-boot understands **

   ** To install a new kernel use these commands **
   flash_eraseall /dev/mtd4
   cp zImage.img /dev/mtd4

7. SNMP

   tar -xf net-snmp-5.4.2-pre2.tar.bz2
   cd net-snmp-5.4.2-pre2.tar.bz2
   ./config_sx560.sh
   cd objarm
   make
   make install
   (Installs to net-snmp-5.4.2-pre2/objarm/install)

8. OpenSSL

   tar -xf openssl-0.9.8g.tar.bz2
   cd openssl-0.9.8g
   make

9. vsftpd

   tar -xf vsftpd-2.0.6.tar.bz2
   cd vsftpd-2.0.6
   make
