Setup the cross compiling environment
The one I used is Sourcery CodeBench Lite Edition, you can get it from its website
Please choose the eabi verison and format tar.bz2(I used arm-2008q3-72-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2)
Untar the file
$ mkdir ~/overo-standalone $ cd ~/overo-standalone $ tar xvjf arm-2008q3-72-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
Add the bin to your PATH
$ export PATH=$PATH:~/overo-standalone/arm-2008q3/bin
Write the program
The following two Hello World program has been tested on an overo
You can play with them
Compile the program
Assembly verison
$ cd asm/
Use make to compile the asm program
$ make
Boot.asm
File:Example.jpg
C version
$ cd c/
Run the compile file in c program folder
$ sh compile
Run the program
You needed a flashed, bootable MicroSD. You can make one by using Sakoman's scripts (mkcard.sh and mksdcard.sh)
Copy the .bin file generated by the compiler to the boot drive on the SD card
$ cp *.bin /media/boot/
Umount the SD card
$ umount /media/boot $ umount /media/rootfs
Plug the SD card in overo and connect the overo on a Tobi expansion board
Power it up and go into serial console
When the console prompt "Hit any key to stop autoboot", please hit any key
# mmc list # mmc part # fatls mmc 0:1 # fatload mmc 0:1 0x80200000 uimage # go 0x80200000
By now you should see "Hello world!" poping in the console
