Building uClinux on Ubuntu

The article describes how to build uClinux on your Linux, i.g. Ubuntu…

.

For cross compile, we should install some cross toolchain…

$ wget http://www.uclinux.org/pub/uClinux/a...ls-20030314.sh
$ ./arm-elf-tools-20030314.sh

But it will pop up an error: tail: cannot open `+43′ for reading: No such file or directory

[FIX]:

$ sed ‘s/^tail /tail -n/’ arm-elf-tools-20030314.sh > arm-elf-tools-20030314.sh.tmp
$ chmod +x arm-elf-tools-20030314.sh.tmp
$ sudo ./arm-elf-tools-20030314.sh.tmp

.

Download uClinux source, and unzip it

$ wget http://www.uclinux.org/pub/uClinux/d...0040408.tar.gz
$ tar -zxvf uClinux-dist-20040408.tar.gz

.

To compile uClinux source, you have to install some library

$ sudo apt-get install ncurses-dev tcl tk

.

Change to the root of uClinux-dist, and enter those command to build it

$ make xconfig
$ make dep
$ make

.

Good idear to run image on skyeye if you donot have any board on hand.

.

Install skyeye as this:

$ sudo apt-get install skyeye

.

Also, skyeye needs an configure file: skyeye.conf, create it, and its content should be:

#skyeye config file sample
cpu: arm7tdmi

mach: at91

mem_bank: map=M, type=RW, addr=0×00000000, size=0×00004000
mem_bank: map=M, type=RW, addr=0×01000000, size=0×00400000
mem_bank: map=M, type=R, addr=0×01400000, size=0×00400000, file=./boot.rom
mem_bank: map=M, type=RW, addr=0×02000000, size=0×00400000
mem_bank: map=M, type=RW, addr=0×02400000, size=0×00008000
mem_bank: map=M, type=RW, addr=0×04000000, size=0×00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0×10000000

.

What’s the file: boot.rom, create an link from images/romfs.img in the root directory of uClinux-dist

$ ln -s images/romfs.img boot.rom

.

And now, you could skyeye it as this:

$ skyeye -e linux-2.4.x/linux

.
