TMDSEVM437X: Internet access

Part Number: TMDSEVM437X

Hi Experts,

I would like to access to an URL with qt browser in the demo through internet connection by the Ethernet.
Does it work with the newest image called "am437x-evm-linux-06.01.00.08.img.zip".

Thank you for your check.

Best regards,
Hitoshi

  • Hi,

    Yes qt browser should work through an ethernet internet connection. Please note the SDK is tested and only supported for basic driver operation on a local subnet. 

    The issues that will have to be dealt with is how the internet connection is made available, we don't have a set of exact steps as each connection to the internet probably varies. The steps I am about to provide are suggestions and not supported by TI, only local subnet connections are supported.

    If behind a firewall you will most likely have to export proxies, here is a rough example of steps to do when running on a TI EVM to run the browser:

    /etc/init.d/matrix-gui-2.0 stop

    udhcpc

    export http_proxy=http://<your internal  proxy sever address>:<internal proxy server port>

    export https_proxy= http://<your internal  proxy sever address>:<internal proxy server port>

    /usr/share/qt5/examples/webenginewidgets/simplebrowser/simplebrowser --no-sandbox https://web.basemark.com

    If the internet connection is direct without a firewall then you will have to setup a path to a domain name server (DNS) to determine paths to your web destination, again this is a rough example you will have to perfect:

    Edit the /etc/resolv.conf file on the target board file system with the vi editor like this > "vi /etc/resolv.conf"

    Now enter the addresses of DNS name servers (like below) and then save file and reboot the target board. These server name examples are located here the Dallas/Ft Worth area. You search on the web for additional DNS ip addresses and enter them in this file. This setup of the resolv.conf is not unique to TI. Therefore there are several examples of resolv.conf files for internet access that can be searched for on the web. This is just one example, you may need several nameserver addresses in your resolv.conf file.

    nameserver 72.3.128.240

    nameserver 72.3.128.241

     After you set up the nameservers in the resolv.conf file you the steps above except for the export statements to launch the browser.

    Best Regards,

  • Hi Schuyler,

    Thank you very much for your kind explanation.
    I was not able to access the internet unfortunately.
    However, our customer is working on it.

    Please close this inquiry.
