Linux/AM3352: AM335 SK EVM with SDK5.0.3 QT GUI is very slow

Hello,

Do you mean that you are trying to launch the qt icon from Matrix GUI and you are observing this issue?

Here is the guide how you could execute qt demos from console and matrix gui guide:

software-dl.ti.com/.../Foundational_Components_Graphics.html 

http://software-dl.ti.com/processor-sdk-linux/esd/docs/05_03_00_07/linux/Examples_and_Demos_Matrix_User_Guide.html

Do you observe the same problem when mouse is connected to the board?

Best Regards,

Margarita

Hi M:

Thanks for helping.

I did see some examples from here:

   /usr/share/qt5/examples

My purpose is how to active / run those examples from the command line.

I cannot use the USB mouse here due to I need to adapt the USB camera for running DeepLearning APP.

Since SK EVM only have 1 USB - type A socket....

THanks.

BR Rio

Hi M:

Thanks for the helping.

My directly answer is : I tried to run the "ArmNN" demo application on the AM335 + SDK503.

Due to the GUI is too slow, may you tell me how to execute the ArmNN demo app from the command line?

There is no file like the ./Calculator as your previous reply.

Thanks.

BR Rio

Hi M:

I found the runArnnnLiveCam.sh.

However, my external Camera USB for AM335 seems not working.

How to solve this?

Hello Rio Chan,

I see that you are running multimediawidgets/camera demo.

I guess you are observing black screen with QT camera demo. 

Please refer the below thread:

https://e2e.ti.com/support/processors/f/791/t/605939 

We do not support QT demos for camera capture. 
You could use v4l2 for capture. 

In additional you could open a new thread about USB capture.

Hope this helps.

Best Regards,
Margarita

Hi M:

It's very strange, I also test the SDK5.0.3 on the AM5 EVM.

The Camera demo is good, and the ArmnnLiveCam demo is good.

Why the Camera is not working on AM335 SK EVM? I don't get it.

BR Rio

Hello,

I have tested ./runArmnnLiveCam.sh on Am572x with camera module and it is working. The camera module is detected as /dev/video1. 

software-dl.ti.com/.../Foundational_Components_ArmNN.html

"

... I need to adapt the USB camera for running DeepLearning APP.

"

I would recommend you to open a new thread about USB camera and DeepLearning App.

Margarita

Hi M:

My E2E post for USB Camera is here:

    https://e2e.ti.com/support/processors/f/791/t/818643

BR Rio

Hi Rio,

The armnn example source code file has hard coded V4L video port number. Currently it is set to 1, while I think in your AM335x board, the USB camera is mounted at port 0. If you change the port number to 0 in line #340 and rebuild the binary using Yocto build, the LiveCamera demo can work for you. 

337 +    size_t i = filename.rfind("camera_live_input", filename.length());

338 +    if (i != string::npos)

339 +    {

340 +      cap = VideoCapture(1);

341 +      namedWindow("ARMNN MobileNet Example", WINDOW_AUTOSIZE | CV_GUI_NORMAL);

342 +      input_type = INPUT_CAMERA; //camera input

343 +    }

Hi Manisha:

You mean the file system needs to rebuild?

Sorry, do we have the FileSystem Rebuild by using Yacto instruction?

BR Rio

Hi Rio,

You do not need to build entire filesystem in Yocto but just the ArmNN application. Check this link on building through Yocto. Search for armnn recipe and rebuild that. 

Hi Manisha:

Sorry, I'm not familiar with the Yocto build.

Please review my SOP attached here.

Do you think it's correct procedure to build the TI_SDK (not Arago) file system?

I think my Page 3 should be changed according the TI SDK file system? ==> : git clone git://arago-project.org/git/projects/oe-layersetup.git tisdk

What's the Git link for TI SDK file system as the the Line of above shows?

TI_Yocto_Build_Bitback_SOP_By_TI_Rio.pdf

Hi.

So, if I need to create ti root fs, the cmd I need to use is: ==> MACHINE=am335x-evm bitbake tisdk-rootfs-image?

Please confirm.

Thanks.

BR Rio

Hi Manisha:

How to let the bitback know I'm having the Python3.4?

Please see my console as the below.

BR Rio

root@ubuntu:/opt/tisdk# MACHINE=am335x-evm bitbake tisdk-rootfs-image
Sorry, python 3.4.0 or later is required for this version of bitbake
root@ubuntu:/opt/tisdk# python -V
Python 2.7.3
root@ubuntu:/opt/tisdk# alias python='/usr/bin/python3.4'
root@ubuntu:/opt/tisdk# MACHINE=am335x-evm bitbake tisdk-rootfs-image
Sorry, python 3.4.0 or later is required for this version of bitbake
root@ubuntu:/opt/tisdk# alias python='/usr/bin/python3.4'
root@ubuntu:/opt/tisdk# python -V
Python 3.4.5
root@ubuntu:/opt/tisdk#

Hello Rio, 

As Manisha said there is no need to build the entire rootfs. 

Please make sure that you follow this guide:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/05_03_00_07/linux/Overview_Building_the_SDK.html 

Please execute the steps from "Host Setup - Ubuntu (Recommended)"

I would recommend you to check "1.2.3.4 Recipes" chapter also.

It seems to me like you are executing bitbake command in the main tisdk folder not in build folder. Please check the Build steps chapter.

Hope this helps.

Hi M:

Yes, I know the "Recipes". for partial building.

But , before that, I have the problem for using Python3.4 for building.

Please check my log as the below.

Step1: I have met the bitback issue for using Python3.4.

root@ubuntu:/opt/tisdk# MACHINE=am335x-evm bitbake tisdk-rootfs-image
Sorry, python 3.4.0 or later is required for this version of bitbake

Step2: I make the system to find the 3.4.

root@ubuntu:/opt/tisdk# alias python='/usr/bin/python3.4'

root@ubuntu:/opt/tisdk# python -V
Python 3.4.5

Step3: It still told me it cannot find the 3.4.

root@ubuntu:/opt/tisdk# MACHINE=am335x-evm bitbake tisdk-rootfs-image
Sorry, python 3.4.0 or later is required for this version of bitbake

So, what's wrong here?

How to solve this?

BR Rio

Hello Rio,

I tried on my side. I am using Ubuntu 14.04. 

If I execute these steps :

./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-05.03.00.07-config.txt
cd build
. conf/setenv
export TOOLCHAIN_PATH_ARMV7=/home/mms/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf
export TOOLCHAIN_PATH_ARMV8=/home/mms/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu

/tisdk/build$ MACHINE=am335x-evm bitbake tisdk-rootfs-image

I do not see python error.

mms@ubuntu:~/tisdk/build$ bitbake --version

You could check

cd /usr/bin

/usr/bin$ ls -al pyth*

lrwxrwxrwx 1 root root 10 Sep 2 2015 python3m -> python3.4m

The python3 installation should have created a python3 symlink to python3.4. If this didn't happen, create it yourself.

Search in the internet how you could create symbolic link or symlink .

I would recommend you if you still have problem with bitbake to open a new thread. 

Hope this helps.
