DE5a-Net-DDR4 Compilation Problem?


l have a DE5a-Net-DDR4 board installed on my system. I’m trying to compile a simple OpenCL code, but always got error message. i double check that all environment settings are correct. The error message displayed after approximately 25 minutes from the starting compilation process. below is a sample output with errors message displayed :



[root@localhost clfiles]# aoc -g -v -fp-relaxed -report

aoc: Environment checks are completed successfully.

aoc: Cached files in /var/tmp/aocl/user1 may be used to reduce compilation time

You are now compiling the full flow!!

aoc: Selected default target board de5a_net_ddr4

aoc: Running OpenCL parser....

aoc: OpenCL parser completed successfully.

aoc: Optimizing and doing static analysis of code...

aoc: Linking with IP library ...

Compiling for FPGA. This process may take a long time, please be patient.

Always got this error,

below are ssome environment :

[root@localhost bringup]# which aoc


[root@localhost bringup]# which quartus




I appreciate If i can get some help to solve this issue. Any suggestions? Is it because of license file is not the right one, l don’t thinks so as it is working if I add -c option.

Can you post the full quartus_sh_compile.log file? Furthermore, are you using the 17.1 BSP from this page?


Thanks HRZ for your comments, I have this problem solved through contacted the Intel support department.

below is the solution:


Please download *base.qar* file from the link: , then replace the *base.qar* file in the DE5ANET_DDR4_OpenCL_BSP_17.1\de5a_net_ddr4\hardware\de5a_net_ddr4 folder with this new one and test your project again


This solved my issue and the compilation process is done successfully.


Thanks again for offering help.

So, Terasic's BSP is broken, but instead of updating the BSP on their website, they expect people to waste days trying to figure out what is wrong until they contact their support and get the fix from the support? Or maybe they just realized the BSP they released one year ago is broken?


That is why I share the solution, I tried to solve this problem working for more than three weeks!!!!

Thanks again for offering help


note: l tried the latest versions 18.1 but have similar problem.
