OMAP35x-psp-sdk-02.01.03.11 u-boot support yaffs?

hi all

 I write uImage and system.img to nand flash in omap evm board. 
But I get follow error message. Therefore i use sd card boot to mount mtdblock4,but  i see  mtdblock4 display lost+found.

How to solve this problem?

---------------------------------------------------

Failed to execute /init.  Attempting defaults...
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
----------------------------------------------------

The follow is my  step

----------------------------------------------------------------------------------------------------------------------------------------------

 #mmcinit;mw.b 0x87000000 0xFF 0x500000;fatload mmc 0 0x87000000  uImage;nand unlock;nand erase 0xC0000 0x500000;nandecc sw;nand write.i  0x87000000 0xC0000 0x500000;nand lock 
 #mmcinit;fatload mmc 0 0x87000000 system.img;nand unlock;nand erase 0x600000 0x5F00000;nandecc sw;nand write.i 0x87000000 0x600000 0x5F00000;nand lock
----------------------------------------------------------------------------------------------------------------------------------------------

 My boot parammeter in u-boot 
-----------------------------------------------------------------------

#setenv bootargs mem=128M console=ttyS2,115200n8  root=/dev/mtdblock4  rw rootfstype=yaffs2 init=/init rootdelay=2
#nandecc sw;nand read.i 0x8000C000 0xC0000 0x500000;bootm 0x8000c000
