Hello, hamzaygrtc:
SPE R5 (AON) is the core to run freeRTOS.
As to core clock, please refer to doc/welcome.md.

hi jachen,

I tried to use #include<time.h> library but getting for response time for blink led.
I got following error when compiletion time spe-fw:

timesr.c:(.text._times_r+0x2): undefined reference to `_times'

How could I check response time freertos ?

I mention in this topic clearly. If its not clear.
