Loading hardware platform created in Vivado into SDK fails

[vegajua1]

I am a relatively new user to Vivado and would appreciate some assistance

I am using Vivado 2015.1 to create a project that includes a MicroBlaze device. After successfully generating the bitstream with no errors, I am exporting the Hardware using File->Export->Export Hardware, exporting the file to the project directory and including the bitstream. After completing this, I am launching SDK using File->Launch SDK placing both the exported location and workspace to the project directory. When I launch this, I receive a message saying "Importing Hardware Specification has encountered a problem". The details of this error message say "java.lang.NullPointerException". The log is copied below. I get the same error if I try to directly use SDK to create a new hardware platform and import the design. I am able to program the device using Vivado so the hardware design should be correct. The log in SDK is:

11:46:40 ERROR : Error occurred while creating hardware platform OpenCL_static_wrapper_hw_platform_10 from sysdef java.lang.IllegalArgumentException: Invalid Hardware Specification File provided: /<Folder_Location>/OpenCL_static_wrapper_hw_platform_10/system.hdf at com.xilinx.sdk.hw.internal.HwPlatform.<init>(HwPlatform.java:91) at com.xilinx.sdk.hw.internal.HwSpecFactory.createHwSpec(HwSpecFactory.java:53) at com.xilinx.sdk.hw.internal.HwProjectCreator.createHwProjectFromZip(HwProjectCreator.java:117) at com.xilinx.sdk.hw.HwProjectUtil.internalCreate(HwProjectUtil.java:214) at com.xilinx.sdk.hw.HwProjectUtil.makeNewHardwareProject(HwProjectUtil.java:165) at com.xilinx.sdk.hw.HwProjectUtil.makeNewHardwareProject(HwProjectUtil.java:152) at com.xilinx.sdk.hw.HwProjectUtil.makeNewHardwareProject(HwProjectUtil.java:127) at com.xilinx.sdk.startup.InitSDK.processHwSpecArgumentTask(InitSDK.java:415) at com.xilinx.sdk.startup.InitSDK.access$8(InitSDK.java:397)

Hi,

Can you please share the design(HDF file) for this issue.

Thanks in advance,

Praveen

I solved this problem using the solution to a similar problem in another thread for an earlier Vivado version. It turns out that Vivado can only export files which are not only created but also physically open. When I ran File->Export->Export Hardware, I need to have not only run synthesis, implementation, and bitstream creation, as specified in the manual, but I also need to simultaneously have the block design and the implemented design opened. When I exported the file with these two windows opened, having made no other changes to the design, the file produced was now able to be opened using SDK.

Thanks,
