MCUXpresso IDE Timers List not working

henrynguyen — Thu, 14 Apr 2022 23:04:43 GMT

Hello,

i am using MCUXpresso v11.4.1 (build 6260) with FreeRTOS for MK66

i can see the Heap Usage, Tasks, Queues, Instruction traces, but i can not see my timer under Timers List.

can you please let me know why?

also, i am using Jlink Pro, not sure why i can not do the non-stop debug?

for non-stop debug, what debugger should i use?

Thanks

Henry

You only need to worry about non-stop or full-stop mode if you are using LinkServer (see https://mcuoneclipse.com/2019/01/13/gdb-all-stop-and-non-stop-mode-with-linkserver/). J-Link works does not have (and need) such a setting.

I recommend that you have a read at https://mcuoneclipse.com/2018/05/27/tutorial-understanding-and-using-freertos-software-timers/: you only will see something in the timers list inside Eclipse if the timer is active or running. But you can see all the time the timer daemon task queue.

I hope this helps,

Erich

Hi Erich,

Thank you so much for the answer.

i am using Segger JLINK plus, and have to pause the IDE to view variables or RTOS information (task, queue, etc). i am trying to see real time update RTOS information (heap, task, queue, etc) while IDE is "not" paused. Can you please let me know which probe to do so or which IDE setting that you have experienced?

for the timer, i have it defined and i know it is running because every time the timer expires, the call back function issue an even to run a task and i track the task is running. but still i can not see the timer in the Timers List, please see example below.

Thanks,

Henry

Hi @henrynguyen,

These views are stop-mode-views, so you have to halt/pause the target in order to view the data. They are using gdb expressions which only can be executed with the target paused.

As for your screenshots: I cannot see much because the files/resolution is too low.

Just as a general comment: you might try out the latest version 11.5.1 which just came out, in case you have an older one:

I hope this helps,
