I am using ATSAMV71J21 and I Want to configure UART0 with XDMAC.
I used SPI XDMAC example to configure UART XDMAC settings.
Transmission part is perfectly working fine.
On reception part, i get into XDMAC handler XDMAC_CIS_BIS only after receiving Microblock length of buffer size is reached.
1. But how to get notified when unknown data size is received?
2. How to get UART RX idle line interrupt?
3. How to copy data into user buffer, what is this clean and invalidate D cache and how to use?
4. If i set buffer size as 10 and if I received 4 bytes, how to get notified about this.
Is there any proper UART XDMA example that i can get to proceed further?
Eagerly waiting for your response!
