Simplification is only a few #defines away; for example I have:

Code: Select all

#define CACHE_ALIGN         __attribute__((aligned (32))) __attribute__((section(".ram0")))
#define CACHE_ALIGN_ZERO    __attribute__((aligned (32))) __attribute__((section(".bss")))
#define CACHE_NONE          __attribute__((section(".ram3")))

The section names need to lead to definitions in the scatter file.

You then use them in much the way you envisaged:

Code: Select all

CACHE_NONE uint8_t shortMessageBuffers[SHORT_MESSAGE_COUNT][SHORT_MESSAGE_MAX_LEN + 2] = { { 0 } };

I'd certainly like to see some standard Chibi memory-related definitions; possibly by type of memory rather than anything else (e.g. cached/non-cached, EEPROM, fast/slow etc)
