hi i would like to get an information about storing code size along with code. in lpc3250 (arm 9) there is a macro SIZE_EXT_INFO to store code size. same way, is it possible to store code size in lpc17xx (cortex m3) ? thanks.
It'll be wherever you put it.
Suggest you might place it in an unused vector, at the end of the vector table, with a label you can see in the .MAP file, or using a marker/magic number you can find with a search in a hex editor or such.
