    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.

    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
