Dear Sir/mam,

 

I'm facing one problem in achieving data transfer between two devices through UART interface,

my device is designed based on ADSP21489 in this it is configured for UART transfer in DMA mode.

 

I'm able to transmit the data as per the requirement to the other device, but I'm not able to receive new data (means not refreshing) and it stuck up with first packet of data.

 

please do needful as early as possible and suggest necessary changes or setting for getting refreshing of new data in UART Rx buffer.

 

thanks and regards

satya
