AM6442: UART debug_log output from both A53 and R5F

Hi GR,

Can you tell us the version of MCU SDK you are using ?

BR Vaibhav

Hi Vaibhav,

My customer is using MCU+SDK ver 08.06.04.

Hi GR,

Thanks for your reply.

My customer want to use UART for debug from A53 and R5F in TMDS64EVM.

In baremetal code, we use API as DebugP_log().

However, we can not see data output from only A53 core.

Is there any constraint in the Debug_log APIs using from both some cores?

Are you saying that when you are running the MCU+ SDK example (a53 no rtos) then you are not able to see the desired behaviour of DebugP_log() ?

Whereas for example(r5f no rtos)  you are able to see the output on consoe resulting from DebugP_log() ?

Is there anything neeo to setting as peripheral's ownership in AM6442, if use the peripheral from both some core?

Can you clarify this a little more?

Hi Vaibhav,

Thanks to your support.

Yes, My customer can't see UART1 output from A53.

But In same .appimage, the UART0 output from R5f can saw.

And If set Debug Log -> Enable CCS Log to disable in sysconfig, both UART output was could see.

I thought there was any ownership like C2000 device.

In C2000, I think we have to set peripheral ownership in CPU1 code if CPU2 use any GPIO, peripherals.

Hi GR,

Thanks for the reply.

I will try at my end and check if I am able to reproduce the same issue.

Hello GR,

To be on the same grounds, can you tell me by which method you have initialized the SOC ?

Did you use SBL or SPL ?

Vaibhav

Hi Vaibhav,

My customer initialized SoC using SBL with MCU+SDK 8.06.
