Here we use emmc as media, I attached the kerel_emmc.uuu for reference
Open the cmd.exe, then use the command “uuu.exe kernel_emmc.uuu” to download the image to the emmc on the board as the picture shows
When the board boot up, don’t forget to change the image and fdt_file as you want, for example, I useImage-imx8mqevk.bin as image name and Image-fsl-imx8mq-evk.dtb as my fdt file, you can choose different image and fdt file as uuu file mentions.
For play the video, we can use three solution to support this
a) gplay-1.0 test.mp4
b) gst-launch-1.0 playbin uri=file:///mnt/sdcard/test.mp4
