./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory when I was following the 10Gbps Ethernet Accelerator Functional Unit Design Example user guide

Dear Sir/Madam,

 

I am having a software error issue when I was running the example based on the 10Gbps Ethernet Accelerator Functional Unit Design Example user guide.

error was this

./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory.

 

I just list what I have done here ,any suggestion is welcome.

 

There are two PAC CARD inserted in my server

Check further information including Pr Interface Id and BMC version

Check hssi information as needed as below

root@fig01 sw]# ls /sys/class/fpga

intel-fpga-dev.0  intel-fpga-dev.1

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.0/

device  intel-fpga-fme.0  intel-fpga-port.0  power  subsystem  uevent

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.0/intel-fpga-fme.0/

altr-asmip2.0.auto  bitstream_id        cache_size  dperf   emif_mgmt  fpga_manager           modalias   power  revision   subsystem     uevent

avmmi-bmc.2.auto    bitstream_metadata  dev         driver  errors     intel-pac-hssi.1.auto  ports_num  pr     socket_id  thermal_mgmt  version

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.1/

device  intel-fpga-fme.1  intel-fpga-port.1  power  subsystem  uevent

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.1/intel-fpga-fme.1/

altr-asmip2.3.auto  bitstream_id        cache_size  dperf   emif_mgmt  fpga_manager           modalias   power  revision   subsystem     uevent

avmmi-bmc.5.auto    bitstream_metadata  dev         driver  errors     intel-pac-hssi.4.auto  ports_num  pr     socket_id  thermal_mgmt  version

 

So we can summary as below

PAC Card 0

3B:00:00

intel-fpga-dev.0

intel-fpga-fme.0

intel-fpga-port.0

intel-pac-hssi.1.auto

 

PAC Card 1

D8:00:00

intel-fpga-dev.1

intel-fpga-fme.1

intel-fpga-port.1

intel-pac-hssi.4.auto

 

and further operation will based on above information.

 

[root@fig01 build_synth]# sudo fpgaconf -B 0xd8 -D 0 -F 0 eth_e2e_e10.gbs 

[root@fig01 build_synth]# pwd

/root/inteldevstack/a10_gx_pac_ias_1_2_pv/hw/samples/eth_e2e_e10/build_synth

[root@fig01 build_synth]# cd ..

[root@fig01 eth_e2e_e10]# ls

bin build_synth hw README sw

[root@fig01 eth_e2e_e10]# cd sw

[root@fig01 sw]# make

make: Nothing to be done for 'all'.

the reason was I have done make before, but I can confirm relavant files was generated as below

make file.JPG

 

[root@fig01 sw]# sudo sh -c "echo 10 > /sys/class/fpga/intel-fpga-dev.1/intel-fpga-fme.1/intel-pac-hssi.4.auto/hssi_mgmt/config"

[root@fig01 sw]# sudo chmod 666 /dev/intel-fpga-port.1

[root@fig01 sw]# export LD_LIBRARY_PATH='pwd':$LD_LIBRARY_PATH

[root@fig01 sw]# ./pac_hssi_e10 -b 0xd8 -d 00 -f 00 --action=loopback_enable

./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory

[root@fig01 sw]# 

 

would you please any other test I can try?

 

thanks

 

Jim

Hi,

 

 

 

There is some issue on excuting "export LD_LIBRARY_PATH='pwd':$LD_LIBRARY_PATH" which the current directory is not added into the environment. Please use "export LD_LIBRARY_PATH=$(pwd):$LD_LIBRARY_PATH" which will fixed the issue.
