indeed that is correct, the c2 has a singed binary. as said in my mail, I'm using buildroot to create my images, at the end buildroot takes the file u-boot.bin and burn it into the image at a specific location. the c2 readme explains how to extract the signed blob but I'd expect that it will overwrite part of the u-boot.bin file and no replace it. so I assume I'm missing a part. e.g. u-boot.bin isn't the only file needed from u-boot. am I correct? Thanks. Dagg. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
