Lpc2000

Hi,

I'm currently trying to the same thing (i.e. making a LED blink on
port 1.24 of an LPC2148). I'm using GNU tools and openocd. So far I
haven't succeeded.

Looking at your source code, I believe that you need to assign all
zeros to PINSEL2 register. Writing ones means turning on Debug or
Trace according to the User Manual page 80.

Good luck!

Best regards,

Peter
