Question:
Why refreshing memory window is not working during runtime in legacy processors debug but works in latest processors like SC5xx?
Answer:
The refresh while running is not possible with the legacy processors like 21469 because of the debug architecture of the chip.
In order to access memory, we need to use the core to get it and that involves halting the core.
For the ADSP-SC58x and newer we can get to memory through a system access which can be done without halting the core.
