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?

Error Message:

    What about the other library? Are they present? Just to try to find a solution: comment all the line related with the cache (library and code). DO you have other errors? – Leos313 Mar 02 '17 at 15:56
  • No other errors really - just this singular one. Also bear in mind that the error occurs after the SDK files are generated, thus I had not done anything bad. – Joe Carr Mar 06 '17 at 06:29
  • Share your code and your error message: every thing that gives us the possibility to replicate the same error – Leos313 Mar 06 '17 at 06:57
  • I reverted to an older version of my project which does not have the said problem. Once the error occur again I will post it here. – Joe Carr Mar 06 '17 at 07:28
  • Updated with the error message. – Joe Carr Mar 06 '17 at 08:33

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.

A user writes:

"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."

Here you can find the page.
