FPGA on NI-9145: compilation error

[Lysandros]

Hello everybody,

I use Labview 2017 in order to deploy FPGA code on a NI-9145 Ethercat chassis through a PXIe-8880 controller.

Recently I added a different NI-9145 device, since we are planing to expand the EtherCAT network. Since then, I am facing compilation issues. Apparently the compilation cloud needs memory on the development computer in order to place the FPGA code. The error I get after ca. 20 min. is:

LabVIEW FPGA:  Some of the compilation steps were not executed.

Time (s): cpu = 00:01:10 ; elapsed = 00:00:36 . Memory (MB): peak = 3916.988 ; gain = 0.000 ; free physical = 23933 ; free virtual = 0
INFO: [Route 35-416] Intermediate Timing Summary | WNS=1.228  | TNS=0.000  | WHS=N/A    | THS=N/A    |
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

For some fancy reason, compilation works normally (and pretty fast) on a virtual NI-9145 in the existing EtherCAT-Master. FPGA compilations abort however if I place the VI on the FPGA target of the real, physical NI-9145.

Any help is welcome

Best wishes

Seems it's an FPGA problem and related to your PC. Have you tried rebooting your PC?

Hello,

sounds plausible.

However, I formatted the PC and reinstalled Windows 7 and Labview 2017. The problem remains.

• Windows 7, 64-bit OS
• Labview 2017 SP1 (32-bit)
• Labivew 2017 FPGA Module
• Xilinx Vivado 2015.4 (for local compilation)

Thanks

Hmm, you're still using LabVIEW 2017 FPGA module. I would recommend you upgrade it to LabVIEW 2017 SP1 FPGA module.

Meanwhile, LabVIEW 2107 Real-Time module, CompactRIO 17.6, and EtherCAT 17.6 are also required.

If the problem still exists, you can try increasing the virtual memory and check if will help or not: https://www.youtube.com/watch?v=qyUlDXG4g0E

Thank you.

I installed Labview FPGA SP1 and it seems that it helped. I can compile FPGAs and use I/Os on them. Everything works, except if I discover the NI-9237 C-Module (Strain guage amplifier).  Then the compilatinon crashes, even if this module is not layed on the FPGA, just on the EtherCAT expansion chassis. ..

np

Did you use CompactRIO 17.6 and EtherCAT 17.6?
