Could you please help on below question:

 
I ported my custom BF531 board's code into my custom BF514 board but I never manege to run 2D PPI DMA receive interrupt.

 
 

 
Here below is my custom board's Blackfin pin connections;

 
 

 
PORT F

 
PF0 - PF15 -> PPI0 - PPI15 (16 bit)

 
 

 
PORT G

 
PG5 -> PPI CLK

 
PG6 -> PPI FS1

 
PG7 -> PPI FS2

 
 

 
I looked https://ez.analog.com forums but there is no solved issue or I could not have found it.

 
  

 
You can see my sample code in the attachment.

    Hello Jithul,
    
 
    I also noticed your response a little bit late; yesterday. I tried new code with the points you noticed but again I stuck on the line;
    
 
    while(g_quitWaitLoop);
    
 
     
    
 
    It means there is no DMA PPI interrupt.
    
 
    I use my CMOS sensor in free run mode and I can see all data lines output (D0 - D15), VSYNC and HSYNC and pixel clock (PCLK) coming to BF514 on the oscilloscope. Every thing seem to be OK but there is no interrupt.
    
 
    Best regards,
    
 
    Bora
