jffs2_do_read_inode_internal:

to start with!
It
looks like your writing your JFFS2 image into the rootfs
partition area with an overflow into the jffs2 partition.
When
the kernel boots and attempts to mount the rootfs
partition, it mounts ok but sees the rootfs partition as too small.
For
a JFFS2 image, you should boot from /dev/mtdblock4 and use
u-boot to write your JFFS2 image to the offset for the larger jffs2
partition.
Try the following changes..
erase_fs=nand
erase 0xa00000
0x2100000
nand_rootfs_sz=0x2100000
nand_rootfs_off=0xa00000
Change Kernel command line:
root=/dev/mtdblock4 rw rootfstype=jffs2
ip=192.168.0.100
ea_ethaddr=00:1a:f1:00:00:00 console=ttyS0,115200n8
thanks,
Kevin

[Ltib] LTIB + JVM (SUN)
Hi.
I'm following the tutorial (http://www.imxdev.org/wiki/index.php?title=All_Boards_Java).
I configured LTIB indicating the new image size of 33,792 KB (34603008
bytes).
I edited the u-boot to clear the NAND and save the new image.
erase_fs=nand erase 0x500000
0x2100000
nand_rootfs_sz=0x2100000
nand_rootfs_off=0x500000
What I do not understand is the size of the rootfs on startup.
Creating 5 MTD partitions on
"lpc32xx_nand":
0x00000000-0x000e0000 : "ea3250-boot"
0x000e0000-0x00100000 : "ea3250-ubt-prms"
0x00100000-0x00500000 : "ea3250-kernel"
0x00500000-0x00a00000 : "ea3250-rootfs" (5 MB)
0x00a00000-0x08000000 : "ea3250-jffs2" (120 MB)
Does anyone have any tips?
Regards.
