Hi Dave,
I have checked my timing and DMA settings.
My MCLK is 70Mhz.So JCLK is 140Mhz. DMA burst frequence is 35Mhz.When DREQ0 is asserted,I write pixel data with DACK0='b0,WE,ADDR='b0000.
If I don't write 16(the burst length) words to PIXEL FIFO.Is DREQ0 asserted again or wait for data until 16 words?
I will try to find the number of bytes wrote to adv212.
Thank you!
