After compiling the executable file of ppc, executing make run will not start normally, as shown in the figure below. 

I tried to get the runtime information, but I don't know what to do. I have already #define configGENERATE_RUN_TIME_STATS==1 #define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() ( ulHighFrequencyTimerTicks = 0UL ) #define portGET_RUN_TIME_COUNTER_VALUE() ulHighFrequencyTimerTicks But...
