Can you try to mount /dev/mtdblock0 after doing flash_eraseall /dev/mtd0
(without -j)
As far as I see jffs2 doesn't like an empty flash with cleanmarkers. But
it works fine with an all-empty flash. I think cleanmarkers are written
as data is written.
Another (and maybe better ?) way to go is
* create a jffs2 image with mkfs.jffs2
* erase the flash with -j so that cleanmarkers are written
* and then use nandwrite to write your image to mtd.
