How to debug the board step by step?

[Anonymous]

Hi,

As I know, we can use use the UART to trace the log in the BCM2073X(S).

According to the Information: BCM20732S debug/trace capabilities through the HCI UART port

it seems that we need buy a DSTREAM if we want to debug through SWD. Is it right?

Is there any detail document?

Thanks
