[U-Boot] "nand write.yaffs" is not working as expected
I'm recently using YAFFS2 rootfs on our NAND flash. What I'm experiencing is that the u-boot console "nand write.yaffs" is not working. With this image file, I can successfully write it to nand flash if I boot into Linux. In Linux console, I run "nandwrite -a -o /dev/mtd4 yaffs2.img". And then, I can mount the partition and see what's in it.
In u-boot, with the same yaffs2 image, I'm using "nand write.yaffs ${loadaddr} ${nandrootoffset} ${filesize}", and then I boot into Linux. I can only see a "lost+found" directory on that partition, nothing else.
Anyone ever met the same problem with this "nand write.yaffs" command? I'm wondering maybe I did something wrong?

Have you dump the nand content, and compare with what the content between what uboot does and linux nandwrite does? Also the filesize should be multiple of "writesize + oobsize"
