OpenAVB building issue

[CHM-me-ch]

Hi,

I am trying to get OpenAVB in my Ubuntu 16.04 machine. I am following the steps given in the link : https://github.com/AVnu/OpenAVnu/wiki/Getting-the-source. While building the same, i am getting error when i run the ./travis.sh command. The error i am getting is given in this text file:

erroR.txt

I have also installed the igb driver for intel i210 and the binary is installed in '/lib/modules/4.11.12-rt15/updates/drivers/net/ethernet/intel/igb/igb.ko' igb driver version: igb 5.3.5.12

Also executed the following commands: Install tpciutils : sudo apt-get install pciutils sudo apt-get install g++ sudo apt-get install -y libpcap-dev libpci-dev libsndfile1-dev libjack-dev linux-headers-4.4.0-97-generic cmake sudo cp /usr/src/linux-headers-4.4.0-97/include/uapi/linux/ethtool.h /usr/include/linux

Can anyone please help me to find a solution for this? Any help is highly appreciated. I am a newbie in linux, so please correct me if you find out the mistake i am doing.

Thanks in advance

Hi, any help?

[andrew-elder]

Have you reviewed these steps https://github.com/AVnu/OpenAvnu/tree/master/lib/avtp_pipeline ?

[CHM-me-ch]

No, I haven't. But i will do it now and see. Before continuing, can you please confirm one thing? The kernel version which i am working is : 4.11.12-rt15 , but the linux header is not installed for this. Is that an issue while building OpenAVB code?

When i am running the command : $ sudo ./run_igb.sh eth1 I am getting the error: insmod: ERROR: could not load module kmod/igb/igb_avb.ko: No such file or directory Cannot get driver information: No such device The igb_avb.ko object file is not getting generated. How can I resolve this?

[CHM-me-ch]

I installed the PREEMPT_RT 4.9.47-rt37 and it solved the problem with the creation of igb_avb.ko file.Turns out the 4.11.12 linux RT is not compatible. But still facing errors when trying to run the simple_talker and listener example. I am using 2 intel i210 cards in the same PC where one acts as listener and the other as talker. Can this be implemented?

I am trying to implement the Time triggered send capabilities here, is this already implemented in OpenAVB examples?

[pinealservo]

I don't believe using two of them in one PC is supported right now with the igb-avb driver. But when you run simple_talker it should program the launch time descriptors and send them at the programmed time. The avtp_pipeline code can also be built with support for the igb-avb driver, in which case it will also use the launch time descriptors of the i210.

[CHM-me-ch]

Thankyou for the reply @pinealservo I tried to run the simple talker example but i am getting the following errors:

command: `cd /home/username/Open-AVB/daemons/gptp/linux/build/obj

sudo ./daemon_cl enp1s0 -R 1`

INFO : GPTP [08:43:03:150] gPTP starting ERROR : GPTP [08:43:03:151] Using clock device: /dev/ptp0 STATUS : GPTP [08:43:03:151] Starting PDelay STATUS : GPTP [08:43:03:151] Link Speed: 1000000 kb/sec EXCEPTION: GPTP [08:43:06:184] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:07:199] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:08:214] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:09:229] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:10:243] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:11:258] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:12:273] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:13:288] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:14:303] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:15:317] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:16:332] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:17:347] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:18:362] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:19:377] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:20:391] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:21:406] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:22:421] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:23:435] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:24:450] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:25:465] PDelay Response Receipt Timeout EXCEPTION: GPTP [08:43:26:479] PDelay Response Receipt Timeout

Then I did the Stream reservation daemon as follows: `cd /home/username/Open-AVB/daemons/mrpd sudo ./mrpd -mvs -i enp1s0

[sudo] password for username: process_events() ` It gets stopped here:

Run the simple talker example:

cd /home/username/Open-AVB/examples/simple_talker sudo ./simple_talker -i enp1s0 -t 2 [sudo] password for username: attaching to 0000:01:00.0 MSRP:Empty unhandled from mrpd

What the simple_talker is not working? I have igb_avb driver in the interface. Confirmed using the ethtool -i command,.

Any suggestions or comments will be of great help.

[andrew-elder]

You need to work on getting gPTP to run correctly first. It would appear from the log that the NIC that gPTP is using is not connected to a device that knows how to send a PDelay Response. I would double check your configuration.

I would also switch to using the avtp pipeline code here https://github.com/AVnu/OpenAvnu/tree/master/lib/avtp_pipeline for future testing. There are more people running it more regularly.

[christopher-s-hall]

Adding to @andrew-elder's comment: If you have two PCs connected back-to-back you'll need to start gPTP on both.

I am using 2 intel i210 cards in the same PC where one acts as listener and the other as talker. Can this be implemented?

It is possible to do this with avtp_pipeline, however there are several modifications you'll need to make. The big one is regarding getting the gptp times from the gptp daemon;

The gptp daemon needs to be modified to use two different shared memory locations, and the avtp_pipelines need to be directed to these.

At that point, avtp_pipeline will be able to stream across the nics in some circumstances. This is an issue with how avtp_pipeline (really the igb library) attaches to pci devices.

[andrew-elder]

MRP will need some modification as well. There is a single UDP port used for commands and notifications.

Hello, everyone. I'm having some trouble compiling the project with the AVB_FEATURE_IGB=1. The steps I'm following are:

• Cloning the OpenAVnu repository

• git submodule init

• git submodule update

• Modifying PLATFORM_TOOLCHAIN?=x86_i210_linux in _avtppipeline.mk

• Running sudo ./travis.sh on the root folder of the OpenAVnu repository

After doing this I get the following error:

In file included from /.../OpenAvnu/lib/avtp_pipeline/platform/Linux/rawsock/openavb_rawsock.c:38:0:
/.../OpenAvnu/lib/avtp_pipeline/platform/Linux/rawsock/igb_rawsock.h:36:17: fatal error: igb.h: No such file or directory compilation terminated.

Any idea of why I might be getting this error? Am I missing some installation or library in particular?

Any help is appreciated. Thanks. Best regards, Sofia

Hello, Jakub. Thank you very much, with your help I could build the project!

On my _avtppipeline.mk I set:

    AVB_FEATURE_ENDPOINT ?= 1
    IGB_LAUNCHTIME_ENABLED ?= 1
    AVB_FEATURE_GSTREAMER ?= 0
    PLATFORM_TOOLCHAIN ?= x86_i210_linux

However, when I ran the following:

Talker: sudo ./openavb_harness mpeg2ts_file_talker.ini

Listener: sudo ./openavb_harness mpeg2ts_file_listener.ini

I get a Segmentation Fault error on the listener. Has this happened to you, too? Any idea how can I solve this?

Any help is appreciated. Thank you again. Best regards, Sofia

[JakubMielczarek81]

Hello Sofia, I cannot recall this kind of issue, but it has been a while since I ran such configuration. Maybe you could run listener under gdb or ddd and then you would have some indication where it is crashing. Best regards, Jakub
