I also think that meta-fsl-arm creates a SD-card boot-able image by default, but not sure whether mainline U-boot is in use there or not. Added Otavio for that matter... Albert, any chance that can make it into 2015.1 too? -- Stefan _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
