VP FPGA Compile Error:aarch64_toplevel.cpp:(.text+0x1932): undefined reference to `SimpleCPU::set_pci_bar_handle(int)'

[Hassan313]

I have tried sub steps of step 3 of the below link to install the VP on the FPGA on the AWS:

http://nvdla.org/vp_fpga.html

The version of the hardware is nv_small.

When I run the make command for installing the VP on the FPGA, I am getting the below error:

[centos@ip-172-31-64-62 vp]$ make

Can anyone help me with this issue?

Thank you very much,

Hello, it looks like cmake do not add option "-DAWS_FPGA_PRESENT=1"
So, you can just add "-DAWS_FPGA_PRESENT=1" in vp/models/cpu.build/CMakeFiles/simplecpu.dir/flags.make
CXX_DEFINES = -Dsimplecpu_EXPORTS -DAWS_FPGA_PRESENT=1
Then, make again, it works from my local side.

Dear @taog2018 ,

Thank you very much. I will try it today and let you know if it works on my side too.

Again, I really appreciate your help and support.

Best Regards

Dear @taog2018 ,

I have this issue with sudo modprobe edma-drv which is giving me the below error:

#61

Do you know why I am getting this error?

Thank you very much.

Dear @taog2018 ,

I did as you said, however I am getting new error as below:

ubuntu@ip-172-31-49-14:~/nvdla/vp/models/cpu.build$ nm libsimplecpu.so | grep fpga_pci_poke
U fpga_pci_poke
U fpga_pci_poke8
Hello, I can get this symbol in my local libsimplecpu.so.
'fpga_pci_poke', such kind of function is defined in aws-fpga sdk, please make sure you have already installed aws-fpga sdk.

Dear @taog2018 ,

Thank you so much for your response.

I ran the same command as you, and here is the results:

[centos@ip-172-31-68-107 cpu.build]$ nm libsimplecpu.so | grep fpga_pci_poke
U fpga_pci_poke
U fpga_pci_poke8
[centos@ip-172-31-68-107 cpu.build]$ nm libsimplecpu.so | grep fpga_pci_peek
U fpga_pci_peek
U fpga_pci_peek8
[centos@ip-172-31-68-107 cpu.build]$

It seems that I have the symbols too. Can you kindly advise, what else might have problem?

Thank you very much.

Best Regards
Hassan

Sorry for my mistake. The "U" means this symbol is defined in other library. I suspected that there were something wrong with your AWS SDK.
U fpga_pci_poke
U fpga_pci_poke8
