Make sure bit MATRIXARB.ROM_LAT is set, and PBOOST.Boost contains 3.
Thanks DF9DQ the MATRIXARB.ROM_LAT was indeed set to 0, after setting it to 1 everything works.
However I would consider this a major oversight in the user manual or in the example documentation as this is simply not stated anywhere and one would expect the examples to be run via LPCXpresso in debug mode in which case this example simply won't work. It might have to do with the fact that MATRIXARB is no longer part of the SYSCTL data structure on the LPC 4088 but resides in a different memory location and the chip code doesn't even use it at all. So maybe this is something that should be addressed in either the user manual for IAP or in the examples/lpcopen.
