I just flash my new VIM3 Pro with the VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V0.9-20200530 image (via USB_Burning_tool in windows), everything works perfectly!
Now I would like to try WOL by following https://docs.khadas.com/vim3/HowtoUseWol.html, however, the “Enable WOL” step requires KBI and I have no idea how to boot into U-Boot. I’ve tried “Keys Mode” and “TST Mode” mentioned in https://docs.khadas.com/vim3/HowtoBootIntoUpgradeMode.html but it still boot into Ubuntu.
Here I have two questions:
- USB_Burning_too burns U-Boot into SPI flash and Ubuntu into EMMC storage, do I understand correctly?
- How to boot into U-Boot?
Any help is appreciated, thanks!
