Latest RTOS SDK with memory optimization

[baoshi]

I was looking at the recent RTOS SDK with memory optimization.
It seems ICACHE_FLASH_ATTR has been added onto many FreeRTOS portable functions, especially those xxxFromISR.
I understand the xxxFromISR function are not interrupt handlers, but they may be called from ISRs. It is safe to have them in the flash?
Thanks.

Hi，joostn，

Your topic is using the SDK without OS，yes，it couldn't work in SDK without OS.

And this topic is asking RTOS SDK, it is safe in RTOS SDK ..
