Hello,
I am using the NRF52840 with FreeRTOS and I would like to start the FreeRTOS tick count at a high value for testing purpose.
I have modified the configINITIAL_TICK_COUNT value in the FreeRTOS.h file with a high value : 0xffffffff - 0x1e000 = 0xfffe1fff
(0xffffffff correspond to the maximal tick count, TickType_t beeing a uint32_t value)
(0x1e000 = 2*60*1024 is for 2 minuts, configTICK_TATE_HZ value beeing at 1024)
It should start FreeRTOS tick count at 0xfffe1fff and go back to the zero value after 2 minuts (acctually this is what I want to test), but I have an unexpected result when I use the xTaskGetTickCount() function to see the tick count value (now is the value returned by the xTaskGetTickCount function) :
(FreeTROS.h) #define configINITIAL_TICK_COUNT 0
(LOG) now=4000 (4000 = 3*1024 = 3 sec)
--
(FreeTROS.h) #define configINITIAL_TICK_COUNT 0xfffe1fff
now=3119
I wonld expect the now value to be mutch higer than 4000 (about 0xfffe1fff = 4294844415)
Does anyone know where my problem comes frone ?
Thanks a lot,
Clément
