Using the Memory Browser

Open the memory browser at View → Memory Browser to explore the memory on the CC23xx or CC27xx. In CCS, you can index by address or by symbol name.

Basic BLE Task’s stack (Note the A5 watermark).

GAPRole Task’s stack has probably overflowed as it is completely filled.

The solution in this case would be to increase the stack size for the failing task and see what the stack peak really is. The stackPeak reported in rov_task_detailed_cc2340 is relying on how many watermark bytes are overwritten, so it can’t know how much the overrun amounts to.

Because stacks are utilized from higher addresses towards lower addressed (upwards in the picture), stacks that overrun will tend to overwrite data at locations immediately before the stack.
