I'm trying to migrate a little program, we wrote for the LPC1343 Xpresso-Board to an actual LPC1347 - Board.
Running the code didn't work, when tracing the program I saw it was stopped in the system - setup "system_LPC13xx.c"
at the "while" - line in the sysPLLCLK - Setup:

  LPC_SYSCON->SYSPLLCLKSEL  = SYSPLLCLKSEL_Val;   /* Select PLL Input         */
  LPC_SYSCON->SYSPLLCLKUEN  = 0x01;               /* Update Clock Source      */
  LPC_SYSCON->SYSPLLCLKUEN  = 0x00;               /* Toggle Update Register   */
->  while (!(LPC_SYSCON->SYSPLLCLKUEN & 0x01));     /* Wait Until Updated       */

In the "LPC13xx.h" - file, I can see, that "SYSPLLCLKUEN" is located at offset 44, behind "SYSPLLCLKSEL".

A look to the manuals of LPC1343 and LPC1347 brings a difference in register set:
LPC1343 has in "system control block" at 040 SYSPLLCLKSEL and at 044 SYSPLLCLKUEN,
LPC1347 has SYSPLLCLKSEL at 040 to, but "reserved" at 044.

Is it the reason for this malfunction?

I had a new try with the little "Blinky" - Example. Running it on LPC1343 was no problem - so my environment must not

be so bad. But bringing it to the LPC1347 - board, the program stopped at the same position. 

So do i need another CMSIS-version? I tested CMSISv1P30_LPC13xx and CMSISv2P00_LPC13xx. Has anyone else the LPC1347-board running - with wich CMSIS?

Is there another CMSIS - version available, or what can I do.
