We have some custom made boards with the LPC1857 and the LPC1837. And I found a problem with processor on same of the boards.
Description: The problematic processors can be programmed successfully via an UlinkPro debbuger. But the program won't run. I debugged the program and it stops in a while loop:  
"while (!(LPC_CGU->PLL1_STAT & 1)); "
The other boards which are the same works just fine.
So I assume there is problem with PLL1 clock with some processors. Am I correct and what can we do?
