Hi,

Thanks for providing the logfile. From the logfile, it looks like it automatically loaded with default PCIe driver. Please performed "modprobe -r intel-fpga-pci" then only performed "aocl install".

Thanks.

Here's the output for `lspci -vv | grep acce`:

Hi,

Can you try "lspci -vv | grep acce" to get the kernel driver information.

Hi @JohnT_Intel , Here's the output for lspci

server2@ubuntu:~$ lspci | grep acce
af:00.0 Processing accelerators: Intel Corporation Device 09c4

The FPGA is still available and only shows with lspci and fpgainfo. I think the problem is with the drivers. When I move the FPGA to a different system, It works there.

Hi,

From the latest log, it looks like it is able to installed the driver. Can you double confirm using "lspci" to see if the driver is loaded into the FPGA card?

yes, I have followed the same steps. The problem occurs the same.

The following is the output when I try to uninstall and reinstall the BSP:

Hi,

Have you setup your environment following https://www.intel.com/content/www/us/en/docs/programmable/683831/1-2-1/initializing-the-environment-for-with.html?

Thanks

Hi JohnT, Sorry for the delayed response.

The following are the available files in the linux64 folder

server2@ubuntu:~/inteldevstack/a10_gx_pac_ias_1_2_1_pv/opencl/opencl_bsp/linux64$ tree

2 directories, 8 files

The Installer script extracts the opencl_bsp drivers.

Hi,

Have you check if the BSP is there?
