I have a hang problem on my board based on MPC8377EWLAN, here is how i ran into
problem. We are using u-boot to load the kernel, rootfs and device tree. The
kernel parameters have been set
root=/dev/ram rw rootfstype=ext2 ramdisk_size=131322 console=ttyS0,115200
but I load the rootfs image generated of rootfs.jffs2 (we use buildroot), which
results in kernel spitting the following message and hang. I even enabled the
WDT (mpc83xx_wdt.c) the board does not get reset.
Any ideas would be appreciated.
Thanks
