Hi, all

I want to use the UART to output debug info. from M3(including Video M3 and HDVPSS M3). But how can I access the register of UART from M3?

1. It's possible to access the registers of UART from the both M3 processor?

2.How can I do the address translate from A8 side to M3 side?

 

BTY, I use DM8168 evm board.  Many thanks!

    Hello,

    My understanding is that this is not supported.

    Hi,

     Thanks for your answer. Would you mind give me more detail information why can't support this. The limit is hardware architecture or just software implementation?

    As you konw, each core can always access all of resource in general multi-core architecture. Even in DM8168,  the DSP core 647x also can access the all the peripheral component via the L4 interconnect. So I think both M3 core can also access that. I am right? 

    Thanks again.
