You probably figured it out by now, but the discrepancy is likely due to differing block sizes. barebox documentation has `dd bs=1024`, while the default is 512. boot firmware is a single chunk with barebox, so no separate second stage bootloader partition. > As it differs a bit from evb can i add new dts like in uboot? You can check out the commit adding the EVB or the Pine64 Quartz64: 8d14f8e898b4 ("arm: rockchip: add support for the quartz64 board") Feel free to send patches for your board along the same lines. :) Cheers, Ahmad > > regards Frank > > _______________________________________________ > barebox mailing list > barebox@xxxxxxxxxxxxxxxxxxx > http://lists.infradead.org/mailman/listinfo/barebox > -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 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
