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?

[U-Boot] MPC8313ERDB board reset problem

[Deepak Gopalakrishnan]

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.
