Hello Margarita,
Thats okay.But its regarding openCV.Right?And still i could not setup openCV threw AM5728.
Lets first complete that.I have checked your last post about openCV.There are steps available to setup opencv by using tftp.If i connect keyboard,what should i execute to download .zip file and setup?.

Thanks.

Hello Margarita,
I am also talking about that.Here we can only see tptp option to download the data into EVM.
If i want to clone it directly from EVM i require link to clone it from git(e.g. git clone http://........).So,how can i clone it directly from EVM?

Regards,
Kishan Patel.

Hello,

I am not very sure what you mean. Have you tried wget https://github.com/Itseez/opencv_extra/archive/master.zip

However, you could just cp the opencv_extra-master.zip from you PC to the sd card under /usr/share/OpenCv folder and unzip it there by using unzip command as in the guide.

Hello Margarita,
I want to download it directly into EVM board.
I have tried as you told,check it below:

root@am57xx-evm:/usr/share/OpenCV# wget github.com/.../master.zip
wget: bad address 'github.com'

Hello,

Are you able to ping google.com for example? or open a browser and load some page?

Hello,

Just cp the zip file to the sd card.

I ran this on the board:

./tapi-example-ufacedetect --cascade="/usr/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="/usr/share/OpenCV/haarcascades/haarcascade_eye_tree_eyeglasses.xml" --scale=1.3 /usr/share/OpenCV/testdata/cv/face/100040721_1.jpg

you should wait a bit and do not stop weston.

Here is the result:

on the board:

Hope this helps.

Hello Margarita,
Its looking nice,i appreciate it.Actually,i am booting the board threw eMMC,not using SD card.
Thanks.

Hello,

Then I would recommend you to check your network connection. If you can not ping google.com for example then probably you have a network issue and you must open a new topic regarding this. You could also try the steps with tftp server.

Hello Margarita,
Finally,i have copied .zip file to directory /usr/share/OpenCV.But there are some memory issue.Check it below:

root@am57xx-evm:/usr/share/OpenCV# unzip opencv_extra-master\(2\).zip
Archive: opencv_extra-master(2).zip
creating: opencv_extra-master/
inflating: opencv_extra-master/.gitattributes
unzip: write error: No space left on device

So,should i use sd card? or any other option.

I have also check memory by executing command: "df -h".
It shows as below:

Filesystem Size Used Available Use% Mounted on
/dev/root 3.4G 3.4G 0 100% /
devtmpfs 818.2M 4.0K 818.2M 0% /dev

Thanks.

Hello,

You do not have enough free space.
There is recommendation in the openCV user guide for the sd card size. If I remember right when you extract it, is > 600MB.

Your issue is that you do not have enough free space.
