Are you sure about this? I 'm currently developing with the LPC932 and I got the problem that my code size went over the magic border of 7k.
Before, I had a code size close to 7k and it worked fine. I added some routines and even if those routines were faulty, the rest of the code should still work properly. But If I flash the >7k code to the LPC any code in the <7K sectors works, but the rest does not. I can see it on what the LPC is answering on the serial port when I send him commands. There's something coming, but it's only nonsense. So it seems like the code wasn't flashed into sector 7, even if I erase the pages from 1C00 to 1DFF manually, because I don't know if FM really erases them. The LPC932 does not support flash memory view and because I can't include the philips boot code into my hexfile the CRC checksums for sector 7 will always be different.
Also, if I use the old code (compiled <7k) and recompile it with a smaller optimization level (I use Keil uVision 3) so it gets >7k it does not work anymore.
Problem of FM or of the LPC? Any clue?
TIA!

Do you have any security bits turned on for block 7?
