N3000 Sample Test: Native Loopback fail

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

1. cd sw_sample
2. gcc -o hello_fpga -std=gnu99 -rdynamic -ljson-c -luuid -lpthread -lopae-c -lm -Wl,-rpath -lopae-c hello_fpga.c
3. sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages"
4. sudo ./hello_fpga

[guest@hw-rae-a3-l sw_sample]$ sudo ./hello_fpga

Using OPAE C library version '1.3.3' build 'c6c0d9f'
