TQMa8MPxL - YOCTO Linux BSP documentation

HDMI

The STKa8MPxL supports HDMI. If the BSP version is Scarthgap, the HDMI functionality is included in the default device tree.

For older BSP revisions (Kirkstone and below), the correct device tree needs to be configured in U-Boot as described below:

  1. Interrupt the boot process in U-Boot
  2. Set the U-Boot environment variable fdtfile with the command setenv fdtfile imx8mp-tqma8mpql-mba8mpxl-hdmi.dtb
  3. Save the environment by executing the saveenv command
  4. Boot the kernel using the boot command
