Error code 63003..while running a FPGA prog on Host PC using FPGA reference VI

Question

Hi,
when i run my FPGA program on HOST PC using a FPGA reference vi on windows platform, I get an error code 63003 (FPGA bit file out of date). When I go back, recompile and run the FPGA program on the FPGA target, then shut it and come back to HOST PC and run my application with FRGA Open refence vi, it runs with out any error! Does any one know why I get that error code 63003

Answer 1

This error means that the VI which is downloaded to the FPGA was changed on the host/development system, but has not been recompiled. By recompiling it you resolve this problem.
When a LabVIEW FPGA VI is compiled for the FPGA, the bit stream, which will be downloaded to the FPGA, is stored in the VI file. When LabVIEW RT or LabVIEW Windows attempts to download the bit stream to the RIO card, it makes sure the bit stream corresponds to the VI source code in the same file. This is necessary so that the host application can properly communicate with the VI on the FPGA. If the two are not the same, this error is generated from the Open FPGA VI Reference function in the host application.
