====== VIM1S OS Boot Priority ======

VIM1S is capable of booting from the following devices:

  * eMMC
  * TF Card
  * SPI Flash

The OS image can be flased into the ''eMMC'', ''TF Card'' or ''SPI Flash''.

The default boot priority is:

  - TF Card
  - eMMC
  - SPI Flash

You can also swap the boot priority of the ''eMMC'' and ''SPI Flash'' via the [[products:sbc:vim1s:development:kbi|KBI(Khadas Boot Instructions)]], but the ''TF Card'' will always take the highest priority.

  * Setting the priority of ''eMMC'' above ''SPI Flash''

```shell
kvim1s# kbi bootmode w emmc
```

Then the boot priority will become:

  - TF Card
  - eMMC
  - SPI Flash

  * Setting the priority of ''SPI Flash'' above ''eMMC''

```shell
kvim1s# kbi bootmode w spi
```

Then the boot priority will become:

  - TF Card
  - SPI Flash
  - eMMC
