Which header files are you using ? (i.e. where do you define PINSEL2, IO3DIR etc.)
I used the header files from aeolus development, and there was a mistake with one of
definitions doe IO Port 3. (Copy/Paste mistake - same value for port 2 and port 3)

LPC2292: GPIO-output on P3.29 possible ??? - alipowsky - Jun 1 13:43:00 2005
I want to use P3.29 (Pin 27, P3.29/BLS2/AIN6) as GPIO (output)
The manual says it can be done by setting Bit 6 of PINSEL2 to zero.
my testcode:
PINSEL2 &= 0xffffffbf; // Reset PINSEL2.6 to config P3.29 as GPIO
IO3DIR |= 0x20000000; // Set P2.29 as output
IO3SET = 0x20000000; // Set portpin high
But the pin does not go high ??
Did anybody use this pin as GPIO output already ?
regards
Andreas

The manual says it can be done by setting Bit 6 of PINSEL2 to zero.

IO3SET = 0x20000000; // Set portpin high

I use the Rowley header files. (Crossworks for ARM v.1.4)
Thea are okay. I also checked the assembler code and the adresses
there are as expected:
PINSEL2: 0xe002c014
IO3DIR: 0xe0028038
IO3SET: 0xe0028034
