Trigger for FPGA and UPDATE bit AD9102

Hello everybody,

tried to communicate from FPGA to AD9102 via SPI and after transmission of values (which are in the example6.regval), I do write a 1 to the UPDATE bit in the "RAMUPDATE" register. But I can not have any sine wave (no generated wave).

1- Is the trigger missed? (In the software, there is a trigger option called "Trigger_PIC". So how can I trigger it via FPGA?)

Already tried to trigger via TP30, but unsuccessful. 


2- Is the UPDATE bit in this case wrong?
