xil_cache error in Xilinx SDK

I am working on a small project of mine on Digilent Atlys and after all of the standard generating the netlist and bitstream, and exporting to SDK, I happen to get a weird error which states that the xil_cache.h is not present anywhere (even though it is there).

I need to mention that if I don't add an interrupt controller and a timer it works, but I really do need them.

Has anyone encountered this error before?

Solution

  • Try after setting below environmental variables:

    XILINX = C:\Xilinx\14.5\ISE_DS
XILINX_EDK = C:\Xilinx\14.5\ISE_DS\EDK\bin\nt64

    this is suggested in the Xilinx forum and seems to solve the problem.

    "Magic :-)

    I created a batch file to launch it, as from what I know the path variables persit within that batch file

    I set it to 

    set path=""
XILINX = C:\Xilinx\14.5\ISE_DS
XILINX_EDK = C:\Xilinx\14.5\ISE_DS\EDK\bin\nt64
C:\Xilinx\14.5\ISE_DS\EDK\bin\nt64\xsdk.exe

    Interesting the shortcut to the SDK first contains a link to settings64.bat which I assumed set all these variables correctly, but it looks like it doesnt get them right!

    I have to admit its been a trek just getting this far as the documentation is a bit blurry."
