Kernel freezing when booting with jffs2

[Pedro Aguilar]

Hi,

I have a MPC859T based board with a 4MB AMD flash memory. I want to use it
with linux and jffs2. I compiled the kernel (2.4.25 from DENX) with MTD
and jffs2 support without any problems. Using u-boot I downloaded to the
flash memory the jffs2 image at a position that is the same that the one
used when configuring the MTD partition (0x00100000).
Then I downloaded the kernel (I just have serial access to the board) via
u-boot and boot it.

The problem is that when mounting the jffs2 filesystem it says read-only
(I'm not giving it any read-only flag in the MTD partition) and then shows
the msg 'Warning: unable to open an initial console'

Could you tell me where can I find some related mtd-jffs2 info or how can
I solve this problem?

Thanks in advance!

Here's the complete kernel output at boot time (mtd and jffs2 debug flags
activated):
