I have read the AD-FMCOMMS2-EBZ / AD-FMCOMMS3-EBZ / AD-FMCOMMS4-EBZ HDL REFERENCE DESIGN(AD-FMCOMMS2-EBZ / AD-FMCOMMS3-EBZ / AD-FMCOMMS4-EBZ HDL Reference Design [Analog Devices Wiki]) for a few days, and i have some doubts when using the ise 14.4.
1. What is the function of AD9361 Reference HDL?
In the HDL design i_tx module, what is the purpose of using dds? for QPSK?
2. In NO-OS SOFTWARE ad9361 driver,its main function is to initialize the AD9361?
3. In build the edk project, there is a error as follow,
|'XPAR_AXI_DMAC_1_BASEADDR' undeclared (first use in this function)||dac_core.c||/cf_ad9361_sw/src||line 87||C/C++ Problem|
In the parameters.h file,there are two lines:
If i replace the XPAR_AXI_DMAC_0_BASEADDR with XPAR_AXI_DMA_0_BASEADDR,the error would disappear. The reason is in the xparameters.h file,there is no definition of XPAR_AXI_DMAC_0_BASEADDR .
4. If i want to the performance of AD-FMCOMMS4 with reference disign using the zedboard, am i must to add some real RF signals from RF-in port of S4?
