Hello world

Hi Renaud,

Sorry for mailing you but I couldn't stop myself writing to you. I have struggled a lot to compile barebox for beagleboard and it compiled, however I am not able to load it as I don't get any boot prompt after loading it to beagle board.

Can you share the process of compilation and if configuration file required.

Also I would be interested in the Hello World program. In case if you are able to make it then let me know as well. Hope you dont mind my multiple requests.

Thanks

Hello,
I just loaded barebox on a beagle board and I am experimenting with it.

I was wondering how I could load and execute a simple hello world program.

It looks like I would have to use a module.

Could somebody give me some pointers?

Cheers,
Renaud

Hello Plumbedzero,
Here is what I did:

make omap3530_beagle_defconfig
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi-

I use a 32MB SD card formatted for FAT.

As per documentation,
I copied the file MLO, barebox.bin as u-boot.bin and normal.scr as boot.scr (not used yet) on the SD card.
