this could be anything including bad memory controller configuration. Exactly how far does the prompt get? Do you have a JTAG debugger? Does the same thing happen with the latest & greatest u-boot on git.denx.de?

yes i think i have found wat was the change that was causing the problem. I had changed the value of CFG_ENV_SECT_SIZE(which is present in include/config/MPC8313ERDB.h) from 0x10000 to 0x20000. i had to do this because while i issue the command save, i would get an error
"Saving Environment to Flash... Error: end address not on sector boundary"
Can you help me fix this problem....

I have no idea what code you're running: there is no occurrence of the string "PHY Invalid" in the current nor the v1.3.0 versions of mainline U-Boot. Does this u-boot have support for the USB PHY on your board?
Please try top-of-tree u-boot from git.denx.de and let us know if the problem persists. That u-boot is what's supported here. fyi, board support contributions are welcome here too.
