i.MX8MP Demo experience text interface

mazpeitia_matrix — Thu, 19 Oct 2023 08:10:01 GMT

Hello,

I have generated a Yocto image for a i.MX8MP with the recipe imx-image-full for Linux version 5.15.32_2.0.0.

I am now trying to execute the Demo experience binary to use it with a text interface, as is described in the document "NXP Demo Experience User's Guide":

demoexperience tui

However, when doing so I get the following error, and nothing happens:

qrc:/gui/DemoPage.qml:129:9: Unable to assign QJSValue to QQmlListModel*

I have tried executing the binary from a serial debug interface and through SSH, but the result does not differ.

How may I fix this?

Thnak you

Are you using the NXP i.MX8MP EVK board? For the NXP Demo Experience you can directly refer to https://www.nxp.com/docs/en/user-guide/DEXPUG.pdf

Hello,

No, I am not using the NXP i.MX8MP EVK board, but a conga-QMX8-Plus SOM + conga-QEVAL/Qseven 2.0 carrier.

I do not see how the NXP Demo Experience reference document solves my issue. Could the problem arise because I had no display connected at the time of running the binary in TUI mode? I am not even getting the text user interface that is shown in the reference document.

Thanks

I have connected a display and I have validated that the demoexperience GUI works fine. However, even when the display is connected and workimng properly, I get the error I mentioned in the original post when trying to run the TUI mode.
