AM6442: Debug Port Review for AM6442

Jack
Guru 10076 points

Part Number: AM6442

Hi 

There're questions that customer wants to clarify about Debug Port assignment. Please answer to questions.

1. Is the port for debugging for each core correct?
- Application Port: UART0_RXD/TXD
- Real-Time Port: MCU_UART0_RXD/TXD

2. Is it correct to configure the UART port for each core separately for debugging?

3. What about Isolated core(M4F) ? No debug port assigned?

Thanks.

    It looks good. You can use any UART in the MAIN domain for A53 application debug, and use any UART in the MCU domain for R5F application debug.

    Generally, yes, it is convenient to have a debug UART for each core/domain. But in some projects you might decide not to output debug logs to a console.

    The M4F core is in the MCU domain, you can use any of the two MCU UART for M4F debug console if needed.
