Declaration (src/Test_timer.c:32:23): This is where the function is first introduced before its actual definition. Make sure the section attribute here matches the one you intend to use.
Definition (src/Test_timer.c:51:1): This is where the function's code is actually written. The section attribute here must match the one in the declaration.
Choose which section you actually want to use (.iram1.0 or .iram1.1), and then make sure both the declaration and definition of timer_callback use that same section. Hope this will resolve the warning.
