Regarding use of UART2 as normal peripheral

Hello Support,

I found JTAG pins are not brought outside in Jetson Nano & UART2 is only debug option available. However, can we use UART2 normally apart from using as debug port? I mean configure it debug when needed or else we use it as normal UART port?

Thanks,
jagdish

hello jagdish.karamchandani,

please check Jetson Nano Product Design Guide, Jetson Nano brings three UARTs out to the main connector.
please refer to [Jetson Nano UART Connections] for typical assignments of the three available UARTs.
thanks

Hello Jerry,

I already referred Jetson Design guide from which I came to know UART2 is used for debug purpose. Please find attached snapshot from design guide.
So I want to understand if UART2 could be configured as normal UART attached to some peripheral? & it should be configurable as debug port also.

hello jagdish.karamchandani,

it’s already routed to J41, 40-pin expansion header on devkit.
you may setup connections with pin-8 and pin-10, which are UART TX and RX.
check this, Jetson Nano - UART - JetsonHacks for reference,
thanks

Hello Jerry,

Thanks for clarifying. I just wanted to know if UART2 could be disabled to recover UART2 (peripheral inteface) which is clearly written in link you send.
