Why UART don't send buffer ?

Hello,

 

I can't see how to operate the axi uart for sending only.

There is no interrupt for SendDataHandler(), when trying to send buffer.

I based my code on "xuartns550_intr_example.c" and when I comment out the xxx_recv() routine, I get no interrupt in sending. Without this comment out, the send interrupt works just fine.

Why does the uart transmit depends on reception ? I only want to test transmit - nothing else. In theory there should not be any dependency between sending and receiving,

 

Thank you for any comments,

Ran

Hi,

 

This is already an enhancement request made for the driver functionality.

Re: Why UART don't send buffer ?

Hi Praveen,

 

I'm not sure I understand.

Do you mean that currently this is not possible to send buffers, without waiting and receiving bytes on reciever ?

Why there is such dependency ?

What should I do if there is no receiving , does the senfinf will fail in such case ?

 

Thank you,

Ran
