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,
fe8000000.nor: Found 1 x16 devices at 0x0 in 16-bit bank.

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.
