Hi, I am writing a stream of data to DDR and then reading that data and writing it to sdcard. But the writing on DDR starts when there is valid from my input and ready from AXI DMA. As now i want to write data of ADC to DDR there will be no "ready" from DMA. I want to use in between fifo. First i want to write data to fifo untill an interrupt came and when there is an interrupt transfer fifo's data to DDR and the cycle continues.
Help needed for:
How can i use fifo to write data to fifo and read data from fifo? And Then turn the led on ZedBoard ON when fifo is full.
Regards;
