We are using LPCXpresso v7.9.2 for building various LPC1769 projects. With one project we have hard fault situation that I am investigating. The fault occurs only when the compiler optimization setting is set at -Os (optimize for size), it does not occur when I set it at other levels. (for example -O3)
The problem I have is with the Registers tab of the Develop perspective: When using -O3 optimization, all works well and all registers on the Registers tab are displayed as expected. When I debug the same code, but this time compiled with -Os, then an 'error 37: unknown peripheral name : faults' message is displayed while trying to browse the processor registers. The attachment contains all relevant screen copies... it is an annoying bug, as especially in the situation of a fault one would like to inspect the fault registers...

I can't see how the compiler optimisation level could have any affect like this. Can you zip up and post the .log file from the .metadata folder in your workspace?

Also, it would be interesting to know if you see the same issue using the current LPCXpresso IDE v8.1.4?
