ok, there is no output on scu uart. So its broken before u-boot launch. With nxp vendor boostream (scfw + atf + u-boot-imx) I see some output and a little cmd line. So I have to check the stuff before u-boot first. Best Regards, Oliver _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
