I'd like to base a project for lpc1754 on the lpc1768 demo but I prefer having a makefile. Unfortunately none of the examples features a makefile.
I already use the yagarto toolchain for other ARM (arm7tdmi) projects and I would like to use it for this cortex m3 but I'm not sure what I need to change in my existing makefiles to make them work for cortex.

Take a look at the makefile from the \Demo\CORTEX_LM3Sxxxx_Eclipse\RTOSDemo directory (and several other Stellaris demo directories). It uses a makefile and will include the same port layer files as needed for the LPC1754.

Regards.
