If you are unable to boot NEMS Linux from your microSD card or USB flash drive on a Khadas VIM3 board, please be sure to use the Krescue tool first to perform a full erase of your eMMC. https://dl.khadas.com/Firmware/Krescue/dump/VIM3.krescue.sd.img.gz

You can boot from SD or USB, then install NEMS Linux to the integrated
eMMC storage by typing;

.. code-block:: console

    sudo nems-install
