Other Parts Discussed in Thread: DM3730
I am using DM3730.
I am writing NAND from Android prompt with nandwrite (mtd)utility and then reading them on u-boot prompt.
all the Images except u-boot.bin gives the error, no matter at which location I write in NAND.
I write u-boot.bin with this command
./nandwrite -b 1 -n /dev/mtd/mtd6 -p /update/u-boot.bin -s 0x40000
whenever I execute the following command at u-boot to read the nand:
nand read.i 0x81600000 1B340000 80000
it gives me this errors:
NAND read: device 0 offset 0x1b340000, size 0x80000
Error: Bad compare! failed
Error: Bad compare! failed
......
......
Error: Bad compare! failed
Error: Bad compare! failed
NAND read from offset 1b340000 failed -74
524288 bytes read: ERROR
Even if i try to read my normal u-boot which is working properly with command:
nand read.i 0x81600000 80000 80000
NAND read: device 0 offset 0x80000, size 0x80000
Error: Bad compare! failed
....
Error: Bad compare! failed
NAND read from offset 80000 failed -74
524288 bytes read: ERROR
Please Help....
