Can UARTs on the main domain be used by M4?

yes, only in polling mode.

Daisuke Maeda said:

Does MCU+ SDK support 8 UARTs on the main domain

No, only interrupts are supported.

can you elaborate on the requirement to have 8 UART's .i may be able to help better if you can help me understand the usecase.

Daisuke-san,

there have been requests and we are reviewing what all main domain peripherals we can support 

Currently only polling mode can be supported for the main domain peripherals.

Supporting main domain peripherals from MCU domain is not in the current plan.

We are discussing supporting main domain peripherals from MCU domain with the Software team based on requests from customers. I will update after we have aligned with the software team

Thanks and regards

Processor SDK Linux supports the main domain peripherals with interrupts instead of polling mode for A53, right?

Yes that's true.

Daisuke-san,

Main domain UART will be enabled in SDK version 8.04, which should be available by first week of September 2022.
