Hacking Linux for chumby
From Chumby Wiki
Toolchain
- download the Chumby Toolchain to
/usr
- extract
# 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.
