While doing a kernel backup of an mtd (Memory Technology Device) from /dev/mtd/mtd3ro of a TI board gives many "BCH decoding failed", Here are system info #cat /proc/mtd dev: size erasesize name mtd0: 00080000 00020000 "X-Loader" mtd1: 00140000 00020000 "U-Boot" mtd2: 000c0000 00020000 "U-Boot Env" mtd3: 00500000 00020000 "Kernel" mtd4: 1f880000 00020000 "File System" here is the method used, dd if=/dev/mtd/mtd3ro of=/data/local/tmp/mtd3.bin doing a cat also returns the same error, and here is the error, BCH decoding failed BCH decoding failed yes, the destination has enough space ;) tell me what do you think? Thanks
