PROCESSOR-SDK-AM62P: Regarding Mcu Sdk UART example

Hi Vaibhav,

I need to receive data more than 64 bytes, is it possible?

Hello Sahana,

How many bytes do you wish to read ? Can you specify the exact number?

Hi Vaibhav,

I need to receive more than 2k bytes..in interrupt method only. Seems the Rx FIFO is full and overrun in happening. But to handle overrun, below points are given

the UART_RESUME, is only used in IrDA mode. But how to handle overrun in UART mode, without using hardware flow control.

Hello Sahana,

I am checking with the dev team if the fix for overrun has been implemented in the SDK or not.

Allow me sometime on this.

Vaibhav

Hello Sahana,

Just a quick follow up question.

In the application have you modified the buffer size ?

It is defined as 

#define APP_UART_BUFSIZE

Can you also share with us the application ? Or just list down all the changes you have made including sysconfig and the C code files.

Hi Vaibhav, 

The buffer size was more only.. ISR handling was not implemented properly. So debugged it. Now I'm able to receive properly. Thanks for the support.

Hello Sahana,

Good to hear that your concern is resolved.

Can you tell us if you made any changes for the ISR handling ? Are the changes made in this API ---> App_uartUserISR() ?

If so can you please provide it to us, so that we can debug better and faster for further queries.

Hi Vaibhav,

I'm not using the funct App_uartUaerISR. I have implemented own ISR routine. In the after reading the 64 bytes, I was disabling the interrupt suddenly. 

Thanks,

Hello Sahana,

Thank you.
