You'll need a device tree for your board. If you've built your kernel correctly you'll find it in arch/arm/boot/dts/at91-sama5d4ek.dtb. Set global.bootm.oftree to the path to the device tree file and it should boot. See Documentation/user/networking.rst for a convenient way to get the devicetree onto the board. You can store it for example under /env/oftree 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@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
