Toolchain

# tar zxvf gcc-3.3.2-glibc-2.3.2.tar.gz
  • create Embedix dir and symlink
# mkdir -p /opt/Embedix/usr/local/arm-linux
# ln -s /usr /opt/Embedix/usr/local/arm-linux/gcc-3.3.2-glibc-2.3.2
  • if it does not already exist, open /usr/bin/arm-linux-make with your favorite editor and enter:
#!/bin/sh
echo make ARCH=arm CROSS=arm-linux- CC=arm-linux-gcc AR=arm-linux-ar NM=arm-linux-nm RANLIB=arm-linux-ranlib CXX=arm-linux-g++ AS=arm-linux-as LD=arm-linux-ld STRIP=arm-linux-strip BUILDCC=gcc BUILD_CC=gcc CC_FOR_BUILD=gcc "$@"
exec make ARCH=arm CROSS=arm-linux- CC=arm-linux-gcc AR=arm-linux-ar NM=arm-linux-nm RANLIB=arm-linux-ranlib CXX=arm-linux-g++ AS=arm-linux-as LD=arm-linux-ld STRIP=arm-linux-strip BUILDCC=gcc BUILD_CC=gcc CC_FOR_BUILD=gcc "$@"
  • set /usr/bin/arm-linux-make executable
# chmod +x /usr/bin/arm-linux-make

Kernel

The Alpha Prototype chumby runs a modified linux 2.4.20 kernel.

Compiling the Kernel

In order to build the chumby kernel, you can download the kernel source from chumby_kernel.tgz and build by doing the following:

# mkdir kernel
# cd kernel
# tar zxvf chumby_kernel.tgz
# make menuconfig
(then immediately exit and save the config)
# make dep
# make Image

If all goes well, you should end up with an uncompressed kernel image at arch/arm/boot/Image.
