Hello Folks,

Any feedback are welcome~

NOTE: For VIM series Yocto image doesn’t have the desktop, you will see a black screen on HDMI display, so you need to ssh (ssh root@xx.xx.xx.xx) to it or use the serial debug console to access the terminal, execute weston-terminal on serial debug console to check the weston terminal.

Sounds great! However, the prebuilt image seems not working on my VIM3L device:

$ burn-tool -v aml -b VIM3 -i yocto.img 
Try to burn Amlogic image...
Burning image 'yocto.img' for 'VIM3/VIM3L' to eMMC...
Unpacking image [OK]
Initializing ddr ........[OK]
Running u-boot [KO]

Could you please check it again?

You can add weston compositor and launch a weston terminal to your meta-layer. That is all we use, no need for a desktop. You can also add a Khadas branded background. It will also have an icon on the upper left for a shell terminal. So when it starts it will look good and you can still run stuff like firefox from weston. The .ini will have settings for the default terminal that has non-blank screen.

Yes, weston is supported, and you can launch weston terminal with weston-terminal.
