[Ltib] LTIB + JVM (SUN)

[Fernando Vilmar Palha]

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.
