Missing IRAM_ATTR Macro?

[alxAgu]

Hi, I was trying to use the supposed IRAM_ATTR attribute mentioned in the "2c-esp8266_non_os_sdk" reference manual (p. 158). But after looking everywhere I couldn't find the definition.

My c_types.h file doesn't seem to include it

//NONOS_SDK, c_types.h
#ifdef ICACHE_FLASH
#define ICACHE_FLASH_ATTR __attribute__((section(".irom0.text")))
#define ICACHE_RODATA_ATTR __attribute__((section(".irom.text")))
#else
#define ICACHE_FLASH_ATTR
#define ICACHE_RODATA_ATTR
#endif /* ICACHE_FLASH */

while the RTOS_SDK does have it defined as:

//RTOS_SDK, c_types.h
#define IRAM_ATTR           __attribute__((section(".text")))

Am I missing something here?

Thanks.

Hi, for ESP8266 non OS SDK, it needs not the IRAM_ATTR, the functions will be stored in the iRAM by default; and only with ICACHE_FLASH_ATTR the functions will be stored in the flash.

Thanks @FayeY, I had no idea. I guess the documentation needs to be updated to mention this then?

Document has been updated. See ESP8266_Non_OS_SDK_API_Reference Section 2.2.

I can confirm the documentation has not been updated yet.
