  I've tried to use 11.0592MHz crystal, but with same result:-(

  Maybe isnt the frequency of your crystal?
  The datasheet says the LPC2106 must have a crystal from 10 to 25MHz, and maybe 
  the Flash program expects at minimum a 10MHz crystal to program the UART0 of 
  the LPC.
  I suggest to you to change the crystal to see if it works.
