Hi Everyone,
I'm using blackfin UART0 and trying to Communicate With Docklight(Serial Monitor Application ) buadrate is 115200,
First I prepared A sequance or 48 bytes frame in Doclight
Docklight 48 Bytes Frame is like : 0xfa,0xfa,0x00,0x00,0x00,0x00,................0xaa,0xaa Headder is 0xfa,0xfa and footer is 0xaa,0xaa,
if i send this Frame to Uart (Finboard) i was geting like all 0's means total 48 bytes are getting 0's
unsigned char DOC_RX_BUFF[48];
here is my 2D DMA config: DMA_CFG |= XCNT_INT | DMA_EN | 2D_DMA | Msize08 | XCNT_TRIG |AUTO|WRITE;
DMA_ADDRSTART = DOC_RX_BUFF;
DMA_XCNT = 48;
DMA_XMOD =1;
DMA_YCNT =1;
DMA_YMOD =1;
ACTUALLY IF SEND 48 BYTES THROUGH DOCKLIGHT BLACKFIN UART SHOULD RECEVIE 48 BYTES IN DOC_RX_BUFF AS ARRAY
PLEASE HELP ME WITH THIS THANK YOU...
