Hello everyone,

We are using the i.MX8QXP MEK development board and we are developing Linux-based applications in Yocto.

We have connected the LVDS to the HDMI converter (connected to LVDS0) to connect with the external display monitor.

We can load and boot, u-boot and Linux with rootfs from the emmc card. We can see the splash screen on the HD display in u-boot as well as Linux.

We are trying to develop a user application to display the .jpeg/.jpg HD images(1080p) and user text (logs/ text files) on the HD display.

We are using the following components:

Please suggest a reference/way for developing an application with given components and hardware.
Thank you

Your question seems not to be specific to any of the NXP products, but to be a kind of general Linux development question.

So, first, please refer to generally available Linux developer resources.

Some general Linux development related Application Note documents are available from NXP:

Also, please refer to the documentation, specific to the Linux BSP you use.

Best Regards,
