Hi All,

I have done following for mtd partition in uboot,

=> pri mtdids
mtdids=nor0=fe8000000.nor,nand0=fff800000.flash,spi0=spife110000.1
=> mtdparts
incorrect device type in spi0=spife110000.1

in LINUX

AS mantioned in Chapter 7.8.2 of NXP SDK 2.0-1703 documentation, I cannot see the following output,

Could you support me ?

What can I do for MTD partition?

After that my output is like that..

root@t2080rdb:~# cat /proc/mtd
dev: size erasesize name
mtd0: 08000000 00020000 "fe8000000.nor"
mtd1: 20000000 00020000 "fff800000.flash"
mtd2: 04000000 00010000 "spi32766.0"
root@t2080rdb:~#
root@t2080rdb:~#

Also I have done following things;

setenv bootargs root=/dev/mtdblockx rootfstype=jffs2 rw console=ttyS0,115200

=> tftp 1000000 $nor_jffs2_fs
=> erase $nor_jffs_start_address $nor_jffs_end_address /* erase address and size is decided by
your partition setting */
=> cp.b 1000000 $nor_jffs_start_address $filesize /* flash JFFS2 FS to the jffs2 partition on NOR
device */
The nor_jffs_start_address and nor_jffs_end_addresscan get from (board)_Quick_Strat_Guide or
(board)_user_manual.

and

=> boot

Also I have tried following ;

setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 rw console=ttyS0,115200

tftp 1000000 uImage

tftp c00000 dtb

bootm 1000000 - c00000

it does not work for me,

Thank you for your consideration and time.

Please refer to the following process.

=>setenv bootargs "root=/dev/ram rw console=ttyS0,115200 mtdparts=fe8000000.nor:1m(uboot),10m(kernel),128k(dtb),100m(fs),-(user)"
