I installed the new Intel PAC on my workstation recently and I installed the software stack and opencl on my system to use the board. However, the systems only recognizes the board for a couple of minutes and I can run sample examples on they work fine. However, after around 5 minutes of fpga inactivity the system cannot recognize the baord anymore through "aocl diagnose". And the only solution I found so far it to power off the machine and start it again, which is not a feasible solution for me anymore.
Here are the result of "aocl diagnose" just couple of minutes apart.
before.png file is the screenshot right after start up and after.png is 5 minutes after that without making any changes.
Also, I am using Ubuntu 18.04 on my workstation.
I appreciate it if anybody could help me with that.
Thanks,
Mostafa

Hi,
Please let us know the details

Hi,
Thanks for your response. You were right. I checked the temp as you suggested and it seems like the system is not cooling the FPGA well. I increased my fan speed in order the cool the FPGA, and it is working well after that. I checked the temperature regularly and it was not increasing like before. Do you think it could be harmful to the system since I need to keep the fans running at a higher speed than normal use?

Hi
While it is not uncommon to increase the fan speed, we would advise to check with the workstation vendor to know the pros ,cons and limits of workstation fan speed increase.

Thanks, you are right. I should check that.
