If we had the new documentation online I could answer with a link \o/ It has this in it: The images generated by the build process can be directly written to an SD card:: # with Multi Image support: cat images/barebox-freescale-imx51-babbage.img > /dev/sdd # otherwise: cat barebox-flash-image > /dev/sdd This will overwrite the partition table on the card. It can be preserved with:: dd if=images/barebox-freescale-imx51-babbage.img of=/dev/sdd bs=512 skip=1 seek=1 Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
