Hello,

 

Everything works fine in dds_setup and I can see good sine waves from Vivado hardware manager. But after I used dac_dma_setup(), the uart output showed dac_dma: Sine frequency is 3839740 (is this value correct?). But I couldn't see anything but low noise on the hardware manager (attached). Did I miss anything? Thanks
