It is working for me. Are you running the "hush" shell or the old scripting interpreter? => fdt print /chosen chosen { linux,stdout-path = "/soc8...@e0000000/ser...@4500"; }; => fdt set /chosen bootargs console=ttyUL\ root=/dev/mtdblock0 => fdt print /chosen chosen { bootargs = "console=ttyUL root=/dev/mtdblock0"; linux,stdout-path = "/soc8...@e0000000/ser...@4500"; }; => fdt set /chosen bootargs console=ttyUL\ root=dev => fdt print /chosen chosen { bootargs = "console=ttyUL root=dev"; linux,stdout-path = "/soc8...@e0000000/ser...@4500"; }; Best regards, gvb _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
