What my goal is to create a signal at 2.5 GSPS in cyclic mode with the AD9739a and Xilinx ZC706 in no-os setup. I followed the steps for no-os repository in github and managed to create a DDS signal successfully. Then, I tried to change the code for the DMA configuration. I imported the files given below to the project and called dac_buffer_load and dmac_start_transaction functions to generate a signal defined in look up table. However, no matter which mode it is (cyclic or tlast), the signal is always generated once. Is there any thing I am doing wrong here? You can find my main file attached here.
Thank is in advance. Regards,
