Other Parts Discussed in Thread: TMS570LS1227
I'm calling a function that takes 5 parameters via a function pointer. CCS displays the incorrect value for the 5th parameter...all others are correct. The actual value of the 5th parameter is the value passed to the function since the code executes properly. In the example below CCS shows that pBuffer is 0 but executing the code takes the path for pBuffer equal to 0x5555.
Since this is an ARM processor the 5th parameter is passed on the stack rather than a register. The stack value for the 5th parameter is 0x00005555. It appears that CCS is displaying the wrong 16 bits of this stack value. If I modify the stack location to 0xAAAA5555 then CCS says pBuffer is 0xAAAA.
