Hello,
in uboot i have setting the bootargs variable:
=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> saveenv
If I'm not wrong, the right sequence of commands should be the following:
$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
.. [customizations]...
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- cuImage.lite5200b
and this is the output:
..
CHK include/linux/version.h
CHK include/linux/utsrelease.h
CALL scripts/checksyscalls.sh
CHK include/linux/compile.h
CALL arch/powerpc/kernel/systbl_chk.sh
WRAP arch/powerpc/boot/cuImage.lite5200b
DTC: dts->dtb on file

At this point I've loaded the cuImage and rootfs.uimage on the board:
=> usb start
=> usb scan
=> fatload usb 0 0x03000000 cuImage.lite5200b
=> fatload usb 0 0x04000000 rootfs.uimage
=> bootm 0x03000000 0x04000000
but it still hangs after this:

Where is the problem? The problem is the my rootfs.uimage?
Do you have any idea?
Best regards,

^^^^^^^^^^^^^^^^^^
Doesn't look like you are passing a kernel parameters line. The
kernel probably is booting, but doesn't know where to output the
console. Try adding "console=ttyPSC0,115200".
Cheers,
