I am using cortex m4 along with gcc. I have create 4 threads in freeRTOS, 3 of which are periodic with periods of 10ms, 100ms and 1000 ms. My application runs all 4 threads for 1 instance and then experiences a hardfault.
Here is a log report generated with respective register values
HARDFAULT:ERROR:START OF FULL LOG
HARDFAULT:ERROR:R0 R1 R2 R3 R12 : 0x0 0x20001950 0x10000 0x200020c8 0xa5a5a5a5

I have tried changing the stack size for threads but that hasnt helped in anyway. Here is a link to freeRTOS config file : https://drive.google.com/open?id=0B5lr6ikuuOsxWnBTNjgyNmRZeWc
And this is the main.c that I am using https://drive.google.com/open?id=0B5lr6ikuuOsxb01PbkZDNWkwcEE
Kindly help me out.
What happens if you take out the calls to Task10ms(), Task100ms(),
Task_1000ms()? Does the code continue to run then? You could replace
the calls with simple incrementing variables to see if the tasks are
If that does not help, what happens if you set configUSETICKLESSIDLE to 0?
