Error using Timers with ISR

Postby Ritu21 » Thu Feb 07, 2019 1:34 pm

Hi Team,

I need to send some data to server over HTTP after every 30 mins. To do this, tried using hardware timers (took the help from the given example "timer_group.c").
There are several task running in my code.Getting error after adding timer code with ISR. Backtraced the error as below.

Remote debugging using COM3
0x4008b082 in vTaskSwitchContext ()
at D:/Ritu/ESP32/ESP32-WROMM-32/esp-idf/components/freertos/tasks.c:2869
2869 listGET_OWNER_OF_NEXT_ENTRY( pxTCB, &( pxReadyTasksLists[ uxDynamicTopReady ] ) );
(gdb) bt
#0 0x4008b082 in vTaskSwitchContext ()
at D:/Ritu/ESP32/ESP32-WROMM-32/esp-idf/components/freertos/tasks.c:2869
#1 0x4008cfef in _frxt_dispatch ()
at D:/Ritu/ESP32/ESP32-WROMM-32/esp-idf/components/freertos\portasm.S:406
Backtrace stopped: previous frame inner to this frame (corrupt stack?)

Could you please help me understand what is this error saying??? How to solve this??

Thanks
R.

Pretty hard to say... smells like memory corruption, but that's about all I can make out.
