New ContributorN3000 Sample Test: Native Loopback fail
I try to run Sample Test: Native Loopback by using 'sudo ./hello_fpga', but it gives error
Using OPAE C library version '1.3.7' build '81afe79' Error no matching accelerator: not found
'lspci | grep acc' gives
08:00.0 Processing accelerators: Intel Corporation Device 0b30
I also try to use 'sudo ./hello_fpga -B 0x08' but it gives the same error.
Any idea on how to solve this? Thanks!

Hi,
I might need the below info (PrintScreen will help)
- rpm -qa | grep opae
check the OPAE version, also to confirm the step is correct.
The hello_fpga sample host application uses the OPAE library to test the hardware in native loopback mode (NLB).
I would suggest referring back to session 7.2.1 at link below (for detailed setup)
- https://www.intel.com/content/www/us/en/programmable/documentation/iyu1522005567196.html
- Follow the provided step, please let me know if you facing any problem.
What you have to do is the following
- cd sw_sample
- gcc -o hello_fpga -std=gnu99 -rdynamic -ljson-c -luuid -lpthread -lopae-c -lm -Wl,-rpath -lopae-c hello_fpga.c
- sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages"
- sudo ./hello_fpga
[guest@hw-rae-a3-l sw_sample]$ sudo ./hello_fpga
Using OPAE C library version '1.3.3' build 'c6c0d9f'

Let me know if this helps.

maxddThanks for the reply.
When following the tutorial, I don't know what is this variable '$OPAE_PLATFORM_ROOT'. After installation, I only have two folders. Here is the folder structures. (I only show 2 levels)

Here is the output

Hi Max,
How about the test result of "fpgainfo fme" and "fpgabist" ?
Apologize for wrong doc, can you please try out doc below
- Intel® Acceleration Stack User Guide, Intel FPGA Programmable Acceleration Card N3000
- Page 32/92, Session 6 Native : Loopback
- https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-ias-n3000.pdf
- Please follow the step from extract the package to sudo ./hello_fpga
Just want to ensure that the step is correct, please let me know if you are still unable to get it.
