permission error accessing fpga aria 10

Question

I am getting errors running fpgabist when logged in as an unprivileged user, but it works when using the root account.  Additionally, I see permission denied errors in an strace when attempting to use aocl for any purpose.  The permissions look correct based on the changes made by AOCL_BOARD_PACKAGE_ROOT/linux64/libexec/setup_permissions.sh.  I am unable to run aocl commands under root user until I determine all the necessary environment variables/path updates needed to successfully run them.  This is installed in a shared environment, so unprivileged users would need access to use the cards.

Hi @joeryan,

Thank you for posting in Intel community forum and hope all is well.May I asked if you are trying to get started with the OPAE stack or running OpenCL on A10 PAC?
Which guide that you have followed to setup your environment?Hope to hear from you soon.
Best WishesBB

We were working on using the OPAE stack and were able to finally get an aocl diagnose output.  We have determined that FIM/BMC Firmware upgrades are needed to move to the latest OPAE/IntelDevStack.

As a related question, the archive page for version 1.1 (https://www.intel.com/content/www/us/en/software-kit/665876/intel-pac-with-intel-arria-10-gx-fpga-acceleration-stack-version-1-1.html?) links to FIM/BMC Firmware tools download with (https://www.bittware.com/fpga/intel/boards/pac-arria-10/).  However, this returns a 404 error from Bittware.  I am in the process of registering there, but is that the appropriate place to obtain the different firmware versions to upgrade through the versions to 1.2.1?

Hi @joeryan,

Apologies for the hold up, we have double checked this and supported from bittware with Intel PAC card has been concluded.However customers can still engaged them to purchase a copy of Toolkit LITE, bittware will be more than happy to prepare a quote for that.Hope that helps.
