[U-Boot-Users] U-boot reset problem

Hello,
We are able to build ROM u-boot for MPC8260 based customs board. We have observed a strange behavior of the board. When we power it up at the beginning of the day; it resets and resets. After a couple of power on/off we get the boot prompt. I am giving the log what we get after we power it up for the first time. Any help will be appreciated.

Sounds like a hardware problem to me. Check your power supply and the clock signals.
