Error enumerating AFCs: no driver available

Hi,

I am using OpenCL on an Aria 10 node and have generated an .aocx file. However, when I try to program the FPGA by using:

aocl program acl0 xxx.aocx

This error message pops out:

Error enumerating AFCs: no driver available
Error enumerating AFCs: no driver available
Error parsing device name '����'
aocl program: Running program from /opt/a10/inteldevstack/a10_gx_pac_ias_1_2_1_pv/opencl/opencl_bsp/linux64/libexec
Error parsing device name '����'
Error enumerating AFCs: no driver available
Error programming device
aocl program: Program failed.

 

I ran aocl diagnose command later and saw this error message in BSP Diagnostics:

BSP Diagnostics
--------------------------------------------------------------------
Error enumerating AFCs: no driver available
Error enumerating AFCs: no driver available
Error parsing device name '����'
Error enumerating AFCs: no driver available
Error parsing device name '����'

 

I am wondering what may be the cause of this, since previously everything works fine and I didn't change the .aocx file.

 

Thank you!

Hi,


Thank you for posting in Intel Communities.


Could you please confirm whether you are using DevCloud for fpga?

Also share the node number in which you got this error and the screenshot for the same.



Thanks

Hi,

 

Thank you for the reply.

 

I am using node s005-n007. According to the devcloud_login options this should be a node supporting Arria 10 compiling and programming.

 

The screenshot is attached:

Hi,

 

Thank you for taking care of this!

 

Just a quick follow-up on this issue:

Currently, are there any workarounds regarding this issue, if I still want to run my accelerators on Arria 10 FPGAs?

 

Thank you!
