TDA4VM: How to enable UART2 for serial port loopback test

Hi Gary,

Can you clarify which OS is being used? Linux or RTOS?

- Keerthy

Hello，

We are using the Linux operating system

Gary

Hi Gary,

Thanks for confirming. I have few more questions:

• When you say uart2 do you mean main domain Main_uart2?
• Do you want to use the main_uart2 as the console?

Best Regards,

Keerthy 

Hello，

Is the main domain_ Uart2 and want to use main_ Uart2 as console

Gary

Hi Gary,

Could you please refer to this FAQ on how to switch console to MCU_UART. You will have port that for MAIN_UART2.

Best Regards,

Hello,

1. We did not fully understand your reply, meaning to switch the console to MCU_ After UART, main_ Can UART2 be enabled now? What is the relationship between these two.
How can we modify the device tree to enable UART2? Can you provide an example? Thank you.
3. Switch console to MCU_ How does UART operate?

4.And may I ask if there is a development manual that is convenient to share for reference.

Regards，

Gary

Gary,

This was a reference example. There are 10+ instances of UART. We have written an FAQ to switch to a different UART instance as console.
So this was a reference & I checked if you follow that and do similar changes to MAIN_UART2?

Hello，

we did not see the reference examples or the website of the reference examples you provided. Can we send them again?

Apologies I missed sharing the e2e link before.
