Dear Sir,

 

please find the attachment. I'm developing an application for RS232 communication as per our Interface control Document using UART DMA transfer. I'm able to establish communication and receive data in DMA buffer "rx_data1", but I'm not able get data in "rx_data" array even after some delay or without delay.

 

But when i run the program in step mode it able get data in both arrays, when i run it run mode able to get data in DMA array and not in temp array.

 

please suggest any modifications required in this regard to execute my program correctly.

 

regards

satya
