'xrt_core::error' what(): No IP matching 'cmac_0': Invalid argument while running 'basic' design through C++ host code

[SPala121]

I am trying to run 'basic' design of xup_vitisnetwork example IP through C++ host code (from branch host_xrt).

./rx vnx_basic_if0.xclbin

I am getting following error:

Device created: xilinx_u280_xdma_201920_3 Bitfile loaded 02f89ce5-f48a-e281-ebef-bc274cf47d97 terminate called after throwing an instance of 'xrt_core::error' what(): No IP matching 'cmac_0': Invalid argument Aborted (core dumped)

Build summary of IP is attached: vnx_basic_if0.xclbin.txt

Thanks, we are looking into this issue, come back to you shortly @SPala121

Hi @SPala121, I have just tried to run host_xrt on a single link vnx_basic_if0.xclbin and works fine. CMAC_0 is exactly the instance that should be there, also looking at your .txt file. When running Please make sure you are using latest host_xrt (I see you dind't specify the Allveo ID when running ./rx) and that the xclbin is exactly the one with network cores on link 0.

[SPala121]

Hi @fpgafais , I ran the command with ALVEO ID(but I forgot to mention in the command) ./rx /home/settysha/vnx_basic_if0.xclbin xilinx_u280_xdma_201920_3

Also. I have latest host_xrt and xclbin has network cores on link 0 But still I am facing same issue.

[mariodruiz]

@SPala121 the second argument is an unsigned integer

https://github.com/Xilinx/xup_vitis_network_example/blob/211300afd384808c29d3a02c41a174309c27eee6/host_xrt/exec/alveo_rx.cpp#L33-L37

You should run it like this

./rx /home/settysha/vnx_basic_if0.xclbin 0

[SPala121]

Hi @mariodruiz

I ran this command as well. But it throws same error.

[chenb1981]

56line : auto l1 = AlveoVnxLink(u280, 1); if a single link, I think 2nd param should be 0

[fpgafais]

Thanks @chenb1981, I think he has set to it 0 hence the error is about cmac_0 and not cmac_1, @SPala121 do you mind sharing with us your alveo_rx.cpp?

[SPala121]

@fpgafais here is my alveo_rx.cpp. Actually I have set it to 0.

@SPala121 did you verify the xclbin with PYNQ?

[SPala121]

@mariodruiz I tried with PYNQ as well. I think it is also throwing similar sort of error. I ran following piece of code from jupyter notebook: kernel = pynq.Overlay('vnx_basic_if0.xclbin', device=pynq.Device.devices[0])

print(kernel.networklayer_0.getNetworkInfo()) AttributeError: 'DefaultIP' object has no attribute 'getNetworkInfo'

kernel.networklayer_0.sockets[7]=('169.254.3.10',34098,4321,True) AttributeError: 'DefaultIP' object has no attribute 'sockets'

[mariodruiz]

Did you use any of the existing notebook? Or created your own? It seems that you are not importing the vnx_utils

[SPala121]

@mariodruiz oh my bad. I created my own notebook and didnot import vnxutils. But getting error while populating socket table.

kernel.networklayer_0.populateSocketTable() "Socket list length 16 is bigger than the number of sockets in hardware 0"

Is this a separate issue? Or am I missing something?

[mariodruiz]

Please check this issue https://github.com/Xilinx/xup_vitis_network_example/issues/73#issue-1269063908, can you tell me what commit did you build against to?

[SPala121]

@mariodruiz I have built against the commit that was done 22 days ago

[mariodruiz]

That commit is buggy =(. Please follow these steps to rebuild with the latest (master) https://github.com/Xilinx/xup_vitis_network_example/issues/73#issuecomment-1153619823

@fpgafais I checked the status of compute units on U280 with the following command: sudo xbutil examine -d 0000:81:00.1

This is the output: Xclbin UUID AADDFE86-33C9-B5AB-5E45-71E8890FDF80

Compute Units PL Compute Units Index Name Base_Address Usage Status
0 cmac_0:cmac_0 0x1800000 0 (--)
1 krnl_mm2s:krnl_mm2s_0 0x1810000 0 (IDLE)
2 krnl_s2mm:krnl_s2mm_0 0x1820000 0 (IDLE)
3 networklayer:networklayer_0 0x1830000 0 (--)

We can see cmac_0 present in the FPGA. But the 'xrt_core::error' still there.

[fpgafais]

@SPala121 how many boards you have in your system? Could it be that the bitfile is loaded to a different card?

[SPala121]

@fpgafais I have only one board connected to the host

[SPala121]

@fpgafais @mariodruiz Issue of 'xrt_core::error' got resolved! Basically, we should give IP name as 'cmac_0:{cmac_0}'. In the code it was considering only 'cmac_0'.
