Few lines earlier, it says that the scenario in the document uses ARCH=sandbox, which indeed is an ELF executable for your host system. When building for ARCH=arm though, the resulting ELF isn't meant for running under an OS, even an ARM. Instead the necessary sections are copied out of the ELF according to a SoC-specific layout. >>> I copied the .config file from yocto into the barebox directory.

For testing, you can just kill your partition table, but yes eventually, you will want to copy barebox later in the image. > When I look into the bareboximagefile I see two sections starting with > something like barebox.......UUUUUUUUUUUUUUUUUUUUUUUUUU at offset 0 and > offset 0x1000. > The part at 0x1000 resembles more what I see on my sdcard on offset 0x1000 so > my approach would be to > dd if= bareboximagefile of=/dev/mmcblk0 bs=512 offset=8 skip=8. > What do you think? yes, this should work. > >> >> Cheers >> Ahmad >> >> > Thank you and Best Regards > > hu > -- Pengutronix e.K. | | Steuerwalder Str. 21 | https://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
