Symbols that must remain unmodified are marked with an N in the Modify column Preprocessor symbols used by the application in the simple_peripheral project.

Set to 1, byĮither manually setting the bit in the register view in CCS orīy including from Driverlib and calling the If the exception is IMPRECISERR, PRECISERR can be forced by manuallyĭisabling buffered writes. If the CFSR:BFARVALID flag is set when the exception occurs (typicalįor PRECISERR), the BFAR register in CPU_SCS can be read out toįind which memory address caused the exception. When an access violation occurs, the exception type is IMPRECISERRīecause writes to flash and peripheral memory regions are mostly The CFSR register is available in View –> Registers in CCS. A peripheral module (like UART, Timer, and so forth) is accessed.

A NULL pointer has been dereferenced and written to.Stack overflow or corruption leads to arbitrary code execution.Most exception causesįall into the following three categories. The ARMĬortex-M3 User Guide describes this register. Register CFSR (Configurable Fault Status Register).

With the default setup using TI-RTOS, the exception cause can beįound in the System Control Space register group (CPU_SCS) in the Measured as an offset from the start of the heap heapmgrMemFail The amount of memory allocation failure (instances Global variables: heapmgrBlkMax The maximum amount of simultaneous allocated blocks heapmgrBlkCnt The current amount of allocated blocks heapmgrBlkFree The current amount of free blocks heapmgrMemAlo The current total memory allocated in bytes heapmgrMemMax The maximum amount of simultaneous allocated memory inīlocks (this value must not exceed the size of the heap) heapmgrMemUb The furthest memory location of an allocated block, HEAPMGR_METRICS is defined, the variables and functions listed asįollows become available.
