Hi,
I consider using yaffs2 file system in dm368 ipnc platform.
Other file systems (jffs2, ubifs) are operating well now. but, yaffs2 is still occurred kernel panic.
First I patched kernel and u-boot with yaffs2 patch file. then I config kernel configuration to support yaffs2 file system.
Kernel configuration to support yaffs2 is as follows:
In u-boot config header file:
I made yaffs2 root file system image with mkyaffs2 utill in Makefile as follows:
After above sequence, I build kernel and u-boot again and write u-boot and kernel and root file system.
root file system writting command is :
mw.b 0x82000000 0xff 0x3C68A00; tftp 0x82000000 tftpboot/ipnc_dm368_yaffs2; nand erase 0xa00000 0x3C68A00; nand write.yaffs2 0x82000000 0xa00000 0x3C68A00
But, kernel panic is occurred.
Booting message are :

I guess root file system image or writing root file system to mtd block 3 would have some mistake.
