Hi,

 

We are using trying to use Banana PI M2+ for our application , we mainly use UART and Ethernet on module.

 

uname -a details are below.

 

Linux bananapim2plus 5.15.74-sunxi #22.08.6 SMP Tue Oct 18 07:00:33 UTC 2022 armv7l armv7l armv7l GNU/Linux

 

We Enabled UART 3 by adding below command line on /boot/armbianEnv.txt as 

overlays=uart3

 

Pin Number: 8 & 10 We can able to transmit and receive data for uart3.

 

We need to enable one more UART to communicate, We tried 

overlays=uart2 , We failed to enable, Can anyone guide us to enable one more UART in Banana pi M2+

 

Regards,

I Enabled Uart2 via Sudo armbian-config and Tried accessing port via pins 11,13(Allwinner H3 PA0,PA1),

 

UART2 is enable I can able to Transmit data But I could not able to receive data. Any solution ?

 

I need to use 2 nos of UART's. UART3 is working, 

 

UART0 is used by console . Is it possible to use UART0 by disabling console ? and use it as General purpose Serial port.
