K60N512 .data and .data_init definition.

Hi,

I am trying to resurrect my Freescale Tower TWR-K60N512 (MK60N512VMD100).

The IAR linker is complaining...

Linking

Error[Li005]: no definition for "__VECTOR_RAM" [referenced from C:\Users\Peter Goddard\Documents\Freescale Tower\Kinetis\hello_world\RAM_128KB\Obj\

Error while running Linker

The file startup.c contains the following snippet...

data_ram = __section_begin(".data");

data_rom = __section_begin(".data_init");

data_rom_end = __section_end(".data_init");

n = data_rom_end - data_rom;

The linker is using the standard file

$TOOLKIT_DIR$\examples\Freescale\K60\TWR-K60\GettingStarted\config\K60X_ram.icf

.data and.data_init are not defined in it so how do I define it?

Thanks in advance.

Hi Peter,

Thank you for your interest in NXP Semiconductor products and the opportunity to serve you.

I'd highly recommend you to use the sample code of the TWR-K60D100M and its link is below.
