It actually reads this: #define CONFIG_JFFS2_NAND 1 #define CONFIG_JFFS2_CMDLINE 1 #define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c #define CONFIG_CMD_MTDPARTS 1 // Required for mtdparts command in uboot But the command is not available on my system. Would it help to post my .h or maybe my build log? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
