Help for tests/benchmark/latency_measure run failed on Arduino Due board.

Rodger Lin
I built the test code at "tests/benchmark/latency_measure/microkernel" . It runs well using the qemu mode.
I want to try it on Arduino Due board, built it using: make TEST=max BOARD=arduino_due After the program runs on the Arduino Due board. I got the "failure" with some error items. Here is the result: |-----------------------------------------------------------------------------| | Nanokernel Latency Benchmark | |-----------------------------------------------------------------------------| | tcs = timer clock cycles: 1 tcs is 11 nsec | |-----------------------------------------------------------------------------| | 1- Measure time to switch from fiber to ISR execution | | switching time is 156 tcs = 1857 nsec | |-----------------------------------------------------------------------------| | 2- Measure time to switch from ISR back to interrupted fiber | | switching time is 117 tcs = 1392 nsec | |-----------------------------------------------------------------------------| | 3- Measure time from ISR to executing a different fiber (rescheduled) | | switching time is 367 tcs = 4369 nsec | |-----------------------------------------------------------------------------| | 4- Measure average context switch time between fibers | | Error: tick occurred | |-----------------------------------------------------------------------------| | 5- Measure average time to lock then unlock interrupts | | Error: tick occurred | |-----------------------------------------------------------------------------| |-----------------------------------------------------------------------------| | Microkernel Latency Benchmark | |-----------------------------------------------------------------------------| | tcs = timer clock cycles: 1 tcs is 11 nsec | |-----------------------------------------------------------------------------| | 1- Measure time to switch from ISR to back to interrupted task | | switching time is 119 tcs = 1416 nsec | |-----------------------------------------------------------------------------| | 2- Measure time from ISR to executing a different task (rescheduled) | | switch time is 694 tcs = 8261 nsec | |-----------------------------------------------------------------------------| | 3- Measure average time to signal a sema then test that sema | | Average semaphore signal time 0 tcs = 0 nsec | | Average semaphore test time 0 tcs = 0 nsec | |-----------------------------------------------------------------------------| | 4- Measure average time to lock a mutex then unlock that mutex | | Average time to lock the mutex 504056 tcs = 6000668 nsec | | Average time to unlock the mutex 587911 tcs = 6998948 nsec | |-----------------------------------------------------------------------------| | 5- Measure average context switch time between tasks using (task_yield) | | Error: tick occurred | |-----------------------------------------------------------------------------| | E N D | |-----------------------------------------------------------------------------| =================================================================== PROJECT EXECUTION FAILED

Hi Rodger,
toggle quoted messageShow quoted text
You can first have a try without "TEST=max" option. Besides this, gdb can be used to debug this issue after disabled the other successful indicators. Regards Min
