LPC2378 - Unable to set FAST GPIO

Hi,
I am new to uVision community. I have installed the latest MDK5.21a along with legacy support.

While working on a simple project of toggling GPIO pins with LPC2378, I am unable to change the pin values in the debugger. Out of 6 registers shown in GPIO peripheral window (FIOxDIR, FIOxSET, FIOxDIR, FIOxCLR, FIOxPIN, Pins), last two (FIOxPIN, Pins) remain stuck at 1 always no matter what output I give to the pin.

I dont know whether its a debugger problem as this device is not by default supported or some minor settings issue.

Please help clarify.

  • Thanks for your quick response.

    As you mentioned, I did try to check if there is any specific configuration needed in the configuration wizard, but I couldn't find any. May be you can help me much faster on this.

    Just to clarify - I am not using any external hardware, I am using the inbuilt simulator for debugging.
