Directly in the bullseye ( tiro certeiro no centro do alvo ).
I forgot to set 16K in the block erase size ( was 64K ).
LTIB compiled the kernel and rootfs.jffs2, I mounted it, and voilá, worked!
Now I am working on to understand how to share de NAND flash between YAFFS of LogicLoader and JFFS2 of Linux kernel ( I am using LogicPD Litekit ). Apparently, I need to modify mx31lite.c module, that defines the NAND flash structure, accordingly to a post on LogicPD's forum. It is a matter of time, only.
Thank you very much for your precious advice.
