Part Number:TMS570LC4357
I created a simple demo using the FreeRtos profile for HalCogen and compiled it using CC8.3.0.
The entirety of the code is here:
/** @file HL_sys_main.c
* @brief Application main file
* @date 07-July-2017
* @version 04.07.00
*
* This file contains an empty main function,
* which can be used for the application.

The example runs for about 24 hours then hangs. Breaking into the execution brings me here:
resetEntry
b _c_int00
undefEntry
b undefEntry
b vPortSWI
prefetchEntry
b prefetchEntry
dataEntry
b dataEntry
b phantomInterrupt
ldr pc,[pc,#-0x1b0]
ldr pc,[pc,#-0x1b0]
;-------------------------------------------------------------------------------
The debugger highlights the "b dataEntry" line.
I set the tick rate on the OS config tab to 100Hz.
Any idea why this is happening?
