Hello All please anyone can say, how to compile busybox Where it will generate output. I am using Mini2440 +3.5 lcd board busybox : busybox-1.13.3-mini2440 Toolchain :arm-linux-gcc-4.3.2 Operating system :Fedora 6 Please let me any other tools are required,if required please sugget me the internet path(where can i get). Please let me busy box compilation,to go the things better. Thank you very much
mkdir mini2440-bootstrap
mkdir target
mkdir busybox-1.13.3
and extract the source here
in your host (.profile):
export PATH=/home/user/mini2440-bootstrap/arm-2008q3/bin:$PATH
CROSS_COMPILE=arm-none-linux-gnueabi-
CC=”${CROSS_COMPILE}gcc –march=armv4t –mtune=arm920t”
export CROSS_COMPILE
export CC
navigate to this directory
[busybox-1.13.3] # make defconfig
[busybox-1.13.3] # make ARCH=arm menuconfig
[busybox-1.13.3] # make clean
[busybox-1.13.3] # make ARCH=arm
[busybox-1.13.3] # make ARCH=arm
CONFIG_PREFIX=/home/user/mini2440-
bootstrap/target install
You'll find your output in target
Hello, I have a micro2440 + 1Gb NAND + x35 lcd. I would like ro run linux-kernel-2.6.32.2 and busybox-1.16.0 via NFS. I followed the instruction on this site to do that: http://cchia-cwp.blogspot.com/2010/03/mini2440-friendlyarm-for-embedded.... The problem is that there is always the Kernel panic error! I have added the option user_debug=31 to kernel command-line parameter to see what happened but I couldn't identify the problem. Below is the message sent when the system is booting: U-Boot 1.3.2-micro2440 (May 21 2011 - 21:55:14) I2C: ready DRAM: 64 MB NOR Flash not found.

Hello, Just to say that I have solved this problem. a -march=armv4t option is need for the compiler. Now I can mount the file system but I have another problem with the command-prompt: [\u@\h \W]\# Could anybody tell me where to set these variables : username@host:PWD? Thanks so much! Pascal
