Hi, both dd copies of barebox (with and without offset) reproduced a system which no longer shows anything on the console. Probably I setup something wrong when building barebox.

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://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.pengutronix.de%2F&data=01%7C01%7Chu.schlieben%40codewrights.de%7C94d4466fb4154885110908d7a01fb7b0%7C0974af9b352b437cb606e9f242c0c227%7C0&sdata=pv5a4oMQQIrYqN%2FHq3zoJxONm0QuuJkXOa9UqFPu38Q%3D&reserved=0 | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list [email protected] http://lists.infradead.org/mailman/listinfo/barebox
