Hello,
I'm working with STM32, and a tick each 1 ms.
I get problem with vTaskDelay more than 10000.
I test like this:
before = xTaskGetTickCount();
vTaskDelay(10000);
after = xTaskGetTickCount();
In this case we get exaclty after = before + 10000 and my stopwatch indicates 10 seconds. So far so good.
With a vTaskDelay more than 20000, my stopwatch indicates less than 20 seconds and after != (before + 10000).
I have the same problem with vTaskDelayUntil.
configUSE16BIT_TICKS is set at 0.
I don't understand why? I was thinking that we can program a delay of 4294967295 ms.

What else is your system doing? Try creating a test project that only
creates one task that has no code in it other than the test code you
posted above, and does not use any third party drivers. Do you then
still see the same issue?
