Hi

I'm trying to place at the top of the flash a number of version software.
i already tried

const char test[]="HELLO";
and search the string into the .bin file and i couldn't find it.
I know this method don't put the string into a specific address.

I modify the Memory layout to
Flash   Location 0x0000 size 0x3000
Flash2 Location 0x3000 size 0x1000
then...
__attribute__ ((section (".rodata.Flash2"))) const char test[]="HELLO";
didn't work.

I'm using LPC1115 LPCXpresso Board with LPCXpresso 8.1.4

thanks

the attribute "used" didn't work, but using it in my code did.

__attribute__ ((used,section (".rodata.$Flash2"))) const char version[] = "V01";
__attribute__ ((used,section (".rodata.$Flash2"))) static const char version[] = "V01";

is that ok?

Thanks

Do you use (reference) the variable in your code? If not, the linker will discard it as it is unused. Either use it, or use the "used" attribute.
