debugging

Hello,

On a custom 4460 board. The x-loader hangs at some place when we
reboot. This happens occasionally on an android port by linaro.

I just want to find out how to debug in this case. How can i get to
know where the hang takes place. After boot rom, i can see the mmc clk
toggling
indicating that xloader is in sram when the hang takes place and not
sure where the hang is.

Do i need Lauterbach to debug - Is it possible to connect the emulator
across reboot. If so, how? or is there any other way i can debug this

Also, i want to check - If i can turn off the dplls? If so, how?

I tried to do a disable on all the clocks in the clock list using
clk_disable call just before reboot and that does not seem to help.

Thank you.
ryan
