FPGA memory initialization

[SunJab]

Hi all,

Is there a way to initialize the FPGA memory item from the host VI ? I have used a memory of 1024 elements. In host VI, i generate an array of 1024 elements and import these values to FPGA memory using the 'intialization VI' method and specifying the host VI path as the intialization VI path in memory properties dialog box. But every time i run the host VI, different 1024 array values are generated. Is there any method that every time i run the host VI (not by pressing the Run VI button in memory properties dialog box), the previous contents of the memory are replaced with these newly generated 1024 array elements.

thanks

I believe you'll need to write some FPGA code to do the initialization.  The easiest way would be to use a DMA FIFO to send the array from the host to the FPGA, then read the FIFO on the FPGA and write the memory.
