I ha= ve 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.&n= bsp; The kernel parameters have been set

root= =3D/dev/ram rw rootfstype=3Dext2 ramdisk_size=3D131322 console=3DttyS0,1152= 00

but I load the rootfs image generated of rootfs= .jffs2 (we use buildroot), which results in kernel spitting the following m= essage and hang. I even enabled the WDT (mpc83xx_wdt.c) the board doe= s not get reset.

Any ideas would be appreciated.

Thanks

If you want to use JFFS2, burn it to flash and specify the appropriate mtd device. If you want to use an initial ramdisk, use ext2. Or better, use initramfs (gzipped CPIO archive). -Scott
