As on RedBoot prompt,we set configurations using 'fconfig',is there any Linux tool which does the same ? i tried to do it in my way. # cat /proc/mtd dev: size erasesize name mtd0: 00040000 00020000 "RedBoot" mtd1: 00f80000 00020000 "unallocated" mtd2: 00001000 00020000 "RedBoot config" mtd3: 00020000 00020000 "FIS directory" First i copied 'mtd2' using 'dd' and then changed the binary using 'hexedit' (just changed Boot script). Before booting,I unlocked RedBoot partitions. +++++++++++++++++++++++++++++++++++++++++++++++++++++++ RedBoot> fis list Name FLASH addr Mem addr Length Entry point RedBoot 0x50000000 0x50000000 0x00040000 0x00000000 RedBoot config 0x50FC0000 0x50FC0000 0x00001000 0x00000000 FIS directory 0x50FE0000 0x50FE0000 0x00020000 0x00000000 RedBoot> fis unlock RedBoot ...
