Hello all,

I need help regarding the bootup of linux on MPC8360 MDS Board.

After doing tftp the uImage from u-boot, with the bootm command  the 
kernel gets uncompressed and stops there.
The serial output from kernel could  not be seen.

Source being used:
 uboot - U-Boot-1.1.3
 linux - Linux-2.6.11 supporting mpc8360epb.
board - MPC8360 MDS

The dump is below:

After Uncompressing kernel, nothing comes onto the minicom.
I have tried the console env in bootargs to ttyS0,  ttyS1, ttyCPM0, ttyCPM1, ttyUCC0. But could not succeed.

Anyone Please help me in this regard.

Thanks & Regards
