Hi
I am trying to boot the DVEVM(TMS320DM6446) from the NAND flash, followed
the steps from SPRAAA0(TI)
i have loaded the bootloader into the NAND flash and the board is booting
up
Now i have to load the kernel image and filesystem into the NAND flash
I have created the four partitions in the NAND
dev: size erasesize name
mtd0: 00040000 00004000 "bootloader"
mtd1: 00020000 00004000 "params"
mtd2: 00400000 00004000 "kernel"
mtd3: 03ba0000 00004000 "filesystem"
Can anyone explain me how to load the kernel image and jffs2 filesystem
into NAND flash.
Can i use the nandwrite command for this purpose
The boot log is shown below
