We are working on a platform "MPC5200 lite" with embedded Linux from denx (flavour of Debian) and kernel version is 2.4.25. We are in need of building new kernel image for the same and we face some issues with this. It will be grateful if anybody can throw some light towards solving the issue.
As per the Application note Installing Embedded Linux on Motorola MPC5200 Lite evaluation board, emsys.denayer.wenk.be/emcam/Linux_on_MPC5200_(UK).pdf", page 11, we tried building of Linux Kernel by using the configuration file icecube_5200_defconfig. After downloading the image to the target using TFTP, we tried booting with bootm command. But, the system doesnt boot properly as it is unable to mount root fs, please find the boot up log as follows:
=> setenv bootargs root=/dev/hda1 rw panic=1
=> tftp
