FlexRAN - None FPGA found!

Hi,

We are working on the FlexRAN system and according to the FlexRAN 5GNR Reference Solution 20.08 (Document #603577) we should be able to execute tests on TestMac, but we are getting the same error attempting to initialize FPGAs.

We are working on:

FlexRAN 20.08 running on Dell PowerEdge R740xd.
ICC: 19.0.3.206
DPDK: 19.11
5gnr_sub6, AVX512
No hardware accelerator card present
 
The error we are getting is:
PHYDI-START[from 0] PhyInstance: 0, Mode: 1, Count: 17, Period: 40, NumSlotPerSfn: 80
5GNR Timer Mode
gnb_io_fpga_init: nTimerMode[1] gGnbIoThreadStarted[0]
init_fpga: nFpgaProbe[1] nSecNum[1] nUENum[16] nTimeAdvance[7450] nEthPorts[462607] nPhaseCompFlag[0]
[0]: nDlArfcn[2079427] nUlArfcn[2079427]
probe FPGAs
init fpga fec CfgInfo failed
Error opening the dev node file 1
 
None FPGA found!
 
Please note that phycfg_timer.xml has SW mode set:
<dpdkBasebandFecMode>0</dpdkBasebandFecMode>
 
Is there some other configuration required to allow us to skip this FPGA initialization?
 
If this is not the right place for this question, can you please move it to some other subforum?
 
Regards,
 
Aleksandar

Hi Aleksander,

Did you ever resolve this issue?   We are considering whether or not we actually need an accelerator card since we are running FlexRAN with very low numbers of users (<10)

Would also like to know if there was a resolution to this.  Or hints to troubleshoot?  Thanks.

for FelxRAN v20.08 Release, if you r using  "<dpdkBasebandFecMode>0</dpdkBasebandFecMode>" in Phycfg_Radio.xml, that means you will use DPDK software FEC module to execute your test, instead if using Hardware FEC Accelerator Card.
