According to the manual "ESP8266 RTOS SDK Programming Guide Version 1.4.0" -> "Since ESP8266_RTOS_SDK_v1.2.0, functions are stored in CACHE area by default, need not be added ICACHE_FLASH_ATTR any more."
When I compile my project with void user_init(void) , then I get the error :
build/app.out section `.text' will not fit in region `iram1_0_seg'
When I compile my project with void __attribute__((section(".irom0.text"))) user_init(void) , then the compile is going fine:
Generate user1.1024.new.2.bin successfully in folder firmware/upgrade
Seems to me that the function are not stored by default in CACHE area.
Please advice.
Thanks, Arjan
